Abstract	Changes in flora biodiversity are a dilemma facing managers in order to cope with challenges of extinction or endangering plant species as well as replacement by invasive species. Such problems can occur in the region as disruption of ecosystem balance. The first step of proper management of a watershed is obtaining accurate information about plant communities and their dominance and biodiversity status. Such information will help decision makers to adopt an appropriate management approach. Accordingly, the current study was conducted to detect various types of plant species in Zanjanrood Watershed. For this porous, quadrate and transect methods were applied to determine available plant species in the region. Afterwards, Shannon and Simpson’s Reciprocal indices were used to specify the biodiversity status of the identified communities. The calculation results revealed 3.19 and 5.98 for Shannon and Simpson’s Reciprocal indices, respectively. As the results suggested, there has been a downward trend in biodiversity status over the last 20� years. Such a deteriorating condition has been accelerated rise in recent years so that the non-palatable species are rapidly replaced by the palatable ones due to uncontrolled overgrazing of livestock. If management is not based on principles of sustainability in the region, the watershed will experience an extreme poverty of land cover. The findings would be so helpful to achieve an appropriate strategy in order to conserve the biodiversity in a sustainable manner.

Abstract	One of the main goals of implementation of the Integrated Coastal Zone Management in Iran is to establish sustainable social and economic development in the coastal areas. The main strategy for achieving this goal is by encouraging the economic activities at the coastal areas that are consistent with environmental capacities. Tourist industry has a special place in the national economy, and it plays the most dynamic economic role in sustainable development. A large number of people usually choose this area for recreation as a result of the beautiful landscapes consisting of green forest, hills, rivers and wetland. Therefore, the objective of this study is to determine the optimal tourism sites among various tourism alternatives based on ICZM strategies. This study develops an evaluation model based on the analytic network process (ANP) and the technique for order performance by similarity to ideal solution (TOPSIS), to help the investors in tourism industries, for the selection of the optimal tourism site in the Integrated Coastal Zone Management in a fuzzy environment, where the vagueness and subjectivity are handled with linguistic values parameterized by triangular fuzzy numbers. The ANP is used to analysis the structure of tourism site selection problem and determine the weights of the criteria, while Fuzzy TOPSIS method is utilized to obtain final priorities. A real world application is performed to illustrate the utilization of the model for the tourism site selection problem. Furthermore, for convenience and accuracy in calculating the relative weights of the criteria, Super Decisions software was used. The proposed model adopted in Qeshm Island considers and interprets the effectiveness and feasibility of the model.

Abstract	Human have been thought to properly use soil and water to provide food and to prevent damages of floods in most parts of the world. Also in Iran the thought of using flood water by collecting and spreading it on the land as well as artificially recharging ground water have also been developed the same as other countries. Therefore in oreder to determine the effect of flood on fertility of soil, and also to prevent reciprocal probable harmfull effect of flood in the spreading areas, study on the effect(s) of flood water spreading seams to be essencial and imprative. Having this in the mind as a background, a study on the effect of flood water spreading in physical and chemical properties of soil in Imamzadeh Jafar-e- Ggchsaranregion, where a flood water spreading project have already been implemented, was conducted. During three years of study, soil samples were taken from 3 soil dephs including 0-15 , 15-30 and 30-45 cm of soil depth of first 3 bands of flood spreading network. The result of variance analysis of the data shows that, the effect of flood spreading on the increase of Clay , Magnisium, Potasium, Organic carbon, Saturating percent, Cation exchange capaaty (CEC) and on the decrease of Silt and Sand percent, exchangables sodium percentage (ESP) , exchangable Sodium (Ex, Na) and amount of total lime of soil in flood water spreading area in comparison to the control area, were significant at 1 to 5% confidence level. Based on the obtained results, it can be concluded that flood spreading can lead to significant positive changes on soil fertility as well as coasing to increase of Nitrogen, Chlorine , Nitrate , Sulphate and Bi -- carbonate of soil. But it should be noted that change in the last mention elements were not significant in the study area.

Abstract	Gully erosion is one of the most complicated and destructive forms of water erosion. In order to prevent this erosion, the important factors controlling gully heads must be understood. This paper examines gully head advancement in the Hableh Rood Basin, Iran by (1) observing gully head advance between 1957 and 2005 using field studies, aerial photography and GIS analysis and: (2) applying and evaluating widely used experimental models including the, Thompson (Trans ASAE 7(1):54-55, 1964), SCS (I) and SCS (II) models, for estimating migrating headcuts over the study period. The results showed that the highest mean gully advancement (0.26 m year ⁻ ¹) took place during the 1956-1967 period, with most gullies having lower and steady headcut retreat rates between 1967-2000 (0.21 m year ⁻ ¹) and 2000-2005 (0.15 m year ⁻ ¹). This suggests that the majority of gullies in the study area were still in the early stages of formation in the first study period and their formation may be linked to land use or climatic changes pre 1956. Analysis of the correlation between environmental characteristics of the study area and gully advancement indicated that the upslope area of head cuts and soluble mineral content of the soil were the two most important factors influencing the spatial and temporal variation of gully longitudinal development. Results of multiple regression revealed that the simple relation including upslope area and soluble minerals can explain 93% of total variance and relatively reflects the effects of runoff and waterfall process for headcut retreat. Application of statistical error analysis to evaluate the four gully advancement models showed that in comparison to other models, the second model of SCS has more reliable results for predicting longitudinal gully advancement in this study area and other similar regions. However, this study indicates that future modelling in the region should consider the role of soil soluble mineral content in predicting gully advancement.

Abstract	The Objective of this research was the study of effects of banquette and ripping on increasing of agricultural productions and economic aspects and improvement of watershed and quantification of their effects. The trial was acheaved in experimental design esign of split pots With two main tretments anquette (banquette with ripping or a1 and banquette with ripping a2) and three subtreaments (cultivation of Wheat, Barley, and increasing of vegetation covera as b1, b2 and b3 resp.), with three replication. For each in the trainfed condition (average rainfall of 69 mm.), during 6 years. Statical analysis showed that although there were not significant differencebetween the amount of yield of grain, straw an canopy cover of two main treaments, but there were numericaly difference between them. Statistically there were significant difference between the yields of grain, straw and canopy cover of diffetent years of trial. There were sinificant difference between different levels of subtreaments of b1 and b2 in the average yield of grain and straw for whole years of trial. Comparsion of means for percentages of canopy composition based on class of palatability showed that the a2 treatment caused gradual limitation of non palatable speceis of class III.

Abstract	One of the important characteristics of the arid the soils and semi-arid regions is with weakstracturs and also with a bad chemical condition. Because of soil structure in this regions and based on high exchangeable sodium percent, (ESP) it will be damaged by rainfall. Finally in will be increased the rate of erosion, due to dispersion and selling phenomena's. The role of amendment material such as Gypsum (Ca S04, 2H20) in agriculture lands with high (ESP) has been clear. In evaluation of effect of gypsum application and type of applied on the erosion and runoff from unstable sodic soils that covered high percent of marls, this project has been done. For this propose, it had been selected suitable lands and four treatment which were 1) powder of gypsum 2) industrial gypsum (powder) 3) suspension of gypsum, and 4) without gypsum (blank). Each treatment applied on three slope (10-20-30 percent). The amount of gypsum have been used in the treatments were equal 5 ton/ha. The dimensional of plots were about I *2 meter, with 3 replications- After each rainfalls it was estimated the amount of runoff. sediment, PH and EC and the weight of dry sample. During the project it has collected only 8 samples after 8 Rainfall events. The summary of the results are as flowing: I) Application of gypsum has significant effect on reduce of runoff (about 40 %) 2) Application of gypsum has significant effect on reduce of sediment (35%) 3) Between different methods in application of gypsum it wasn't significant effect. 4) Using of gypsum has significant effect on increasing of(EC). 5) Finally, the influence of gypsum on soil acidity wasn't significant (at 5% level).

Abstract	Innovation of different methods to overcome the environmental problems has always been a challenge to human being. Progress in agriculture by providing water and other inventions according to the needs, shows that the mankind puts much effort for his survival. Iran is regarded as an arid or semi-arid country low precipitation, irregular distribution of rainfall in time and low soil fertility are'the problems-of'rehabilitation and extension of cultivated .and pasture lands . Improper use of resources without the knowledge of science and technology has increased the related problems. Therefore, the destruction of cultivated lands has hampered the production of crop plants and has brought about the problem of flood water and its sediments. The amount of sediments in Iran is about two milliard tons, which contain the 11 % of the total sediments in the world (18 milliard tons). This indicates the magnitude of , land degradation in our country. Therefore, to overcome these problems and reduce the damages imposed to natural resources, watershed management science has been developed. The research programs of rehabilitation of destructed watersheds have been proposed to use the potentials of Khajeh area properly. The aims were as follows: 1. Develop ment methods of rehabilitation of destructed watersheds via the use of technological, mechanical, and biological measures. 2. Quantitative evaluation of effect of watershed management to improve the --- __ .cualitv of.nmoff water nhvsicallv and chemically in destructed watersheds. 3. Optimize the utilization of water and soil resources in destructed watersheds and introduce the most proper scientific techniques. In this program, complementary studies. in the station have also been managed in addition to-general-:-study-of- Aji-chai region and- its geology, soildevelopmentand hydrology. Basic studies in the station, resulted in the choice of proper rehabilitation methods with the following goals: 1. Prevention of soil erosion. 2. Soil conservation and regulation of water status in the region. 3. Rehabilitation of the study area by the fast coverage of the soil with plants. 4. Increase the income of the people in the area. To achieve the above "mentioned targets, several measures such as band contours), trench contours, catchments basins, pools to store runoff and sediments, planting trees and shrubs resistant to salinity and rehabilitation of green cover via planting pistachia atlantica, pistachia vera (instead of Hippophae, Atriplex, Famartix l Halloxylon, Zygo phyllum, and forage plants such as" Agropyron elongatum , Aeluropus were considered in the region to recognize the proper method of rehabilitation. Although some preliminary data have been obtained, but the number of years is not enough to have a strong recommendation. Therefore the experimentation is needed to be continued for a second cycle of 4 years. On the whole the following conclusions could ;'l5"e'made on the basis of the preliminary data. 1. The pastures of the area were poor , but after 4 years they could be rated as iritermediate with a grade of 39. The pastures trend are positive since the biomass production has raised from 200 up to 553. 75 kg/ha, where as in the similar untreated pasture no positive changes was observed. Also the density of palatable plants such as Agropyron elongatum, Aeloropus, Trigonella, Bromus japanicus have increased in the experimental area. 2. The pistachio acquired high rate of survival and its growth rate per year was 35 cm. - Pistachia atlantica was medium in % survial and its growth rate was slow. - Atriplex canescens had 2. good survival rate with a 66 em growth per year. 3. Changes of soil fertility in 3 years with several experiments was marked that association coefficient between PH and Ec and "So on is low that is repersentative several changes in soil profile and is as positive random of worked projects. 4. Some chemical changes has been observed in underground water, but the data obtained isnot enough to reach for a conclusion. 5. There is no surface runoff and flood water in the experimental area and some water has been gathered behind the bands in trench contours and behind the bands and wells for a proper utilization. On the other hand, in the untreated area the land destruction is still observed. 6. Band contours, trench contours, pools to store sediments and runoff were efficient to control runoff and sediments, These measures resulted in reclamation of soil and degraded lands. - 7. The Ec of runoff gathered behind bands and contours ranged 1-1.7 ms/cm while the Ec from control basin was 4-7 ms/cm. 8. The recorded TDS from flood water in untreated area is about 230-250 gr/lit, while in the experimental site is very low (50 grllit). 9. The EC of wells from untreated area was greater than 20 ms/cm and the water is of poor quality compared to water gathered from surface runoffs and bands. Therefore the salinity of Aji-chai river is possibly influenced from underground waters.

Abstract	Growth of population is the main factor for production of more foods. Aditional food production requires aditional soil and water resources or optuimum use of these resources. generally, soil and water' res~urce are limited, optimum use of these resources are very important. In the most part of Iran, annual precipitation is very low with nonuniform distribution in time, space, intensity and duratin. Mostly, high intensity rains produces strong storms which results high damages. Ground water recharge is very low, and. high ground-water pumping declines the water table in aquifers, and sometimes results subsidence of ground surface. In the arid and semiarid regions, due to high groundwater pumping compare to natural groundwater recharge causes shortage of ground-water storage, and, it has been supposed that these type ofaquifers are' poor with very low storge sufficient, but actually these aquifers with high permeable formation have a high potential to store water. So, optimum use of floods by controlling and spreading of storm water on the land, can change the deserts to green zones and forests with high groundwater storage. The study region with on area of 422. 5 km2 is a part of the Garebaiegan region, which is formed from connection of plains and Jabalbares mountain.this watershed is located at Alluvial fan. The Garebaiegan watershed is located between 530 51' to 54° 13' eastern longtitude and 27° 31' to 280 northern latitude. The other characteristics of this area are as follows: The mean annual precipitation of Fasa climatologic station is 2S43 mm, with minimum and maximum of 16mm and 84.5mm respectively. High groundwater pumping due to climatic situation results decline of groundwater surface and requires the artificial grondwater recharge. So, the main objects of this projecte to prevent the sand flow and fixes the soil particles to prepare a suitable bet for plant growth, extention of forests area, Artificial groundwater rechage produces a safe yield for groundwater pumping. Finally, job production and increasing the people in comes can be considerd as parts of project goals. Flood waters spreading method is implementing in 36 stations of Iran. Evaluating of performance of these station are requested. There is some methods and techniques, for evaluating. For this research decision support system is used.

Abstract	Marl formations in Sabzevar region have 100000 ha areas. Marls vegetation is very poor due to their unsuitable physicochemical properties. In this research relationship between marl vegetation and their physicochemical properties studied. Studies localized in establishment area of Salsola, Ephedra and Artemisia vegetation types. In 0-20 and 20-40 % deeps on northern slopes were dug soil profiles. Soil sampeles were taken from two first layers of marl soils. Vegetation properties of all slopes that contain soil profills studied. Soil sampeles in laboratory analyzed and all physical and chemical soil properties determined. Data analyzed by SAS method and relationship between marl vegetations and their physicochemical properties determined. Relation between independent factors (soil factors) and dependent factor (vegetation cover) in all vegetation Types studied by Step wise regression model. In comparison of each average soil factors among three vegetation types revealed that there was significant different in EC, Na, Cl, Sum Cations and Anions, SAR and ESP. In all vegetation types, by increasing in vegetation percent some soil factors such as Ec, Cl, Sum Cations and Anions, SAR and ESP decreased and factors of C, N and P increased. Variation analysis of datas showed that there are significant differences (p0.01) in interaction of plant cover percent with some soil factors such as EC, sand, silt ,Caco3 and gypsum percent, FC, P.W.P, Na, Ca, Cl, Sum Cations and Anions, SAR, CEC and ESP. Furthermore, there are significant differences (p0.05) in interaction of plant cover percent with K, porosity percent and bulk density. Analitical calculation using step wise regression method showed that : 1)- In Salsola Type, correlation between vegetation percent (dependent factors) with FC and EC (independent factors) is meaningful with probability of %99 and with T.N.V and CL is meaningful with probability of %95. 2)- In Ephedra Type, correlation between vegetation percent with EC, K and CEC is meaningful with probability of %95. 3)- In Artemisia Type, correlation between vegetation percent with ESP is meaningful with probability of %99.9 and with T.N.V and SAR with probability of 99 and 95, respectively. So concluded that in Salsola Type FC, EC, T.N.V and Cl and in Ephedra Type EC, CEC and K and in Artemisia Type ESP, T.N.V and SAR have greatest effects on vegetation cover percent, respectively
