    Abstract Urban remnant mountains (URMs) are precious natural green habitat patches that can provide a series of ecosystem services for multi-mountainous cities. The increase in ecological sensitivity and degradation of ecosystem services affected by urban expansion and climate change have led to an increasing vulnerability of urban remnant mountain ecosystems (URMEs). To explore the vulnerability of URMEs, taking the central urban built-up area of the Guiyang city as the study area and URMs as the research object, the vulnerability of URMEs under natural factors and human disturbance was analyzed based on the Pressure-State-Response (PSR) model. The results showed that: (1) Karst rocky desertification, human disturbance, and road density within the buffer zones around URMs were the most important factors affecting the vulnerability of URMEs. Karst rocky desertification was the most likely eco-environmental problem of URMs, and carbon storage was the most important ecosystem service of URMEs. (2) Characteristics of fragile karst habitats in URMs and unreasonable human activities led to high ecological vulnerability, mainly with moderate and severe vulnerability predominating, and the low vulnerability of URMEs when they had moderate park utilization. (3) The ecological vulnerability of small URMs and those distributed in the urban center is higher, and the invulnerable URMEs and the slightly vulnerable URMEs are mainly distributed in the urban edge. The results of this study could provide references for ecological restoration and protection of URMs, and offer a basis for improving the resilience of multi-mountainous cities.

    Abstract Abstract The Tunpu settlements are the historical product of the co-evolution development of the unique geographical and cultural environment of Guizhou and the military defense policies of Ming Dynasty (1368–1644 AD), which created products such as the station troops and station farms. In this study, taking 10 Tunpu settlements in central Guizhou as the research objects, the space diversity of the Tunpu settlement and its influencing factors were analyzed based on the theory and calculation method of plant community species diversity. The results showed that: (1) On the whole, the space α-diversities of the military Tunpu settlements and the commercial Tunpu settlements were relatively high, with strong spatial similarity, while the residential Tunpu settlements had a lower degree of space α-diversity and significant difference. The space α-diversity of different types of the Tunpu settlement presents a variety of changes from the core protected areas to coordinated control areas. (2) There was a significant correlation between the spatial network and spatial morphological indicators and space β-diversity among the Tunpu settlement, and the stepwise regression showed that spatial morphological indicators had a strong explanatory power for the space β-diversity among the Tunpu settlements. (3) The space diversities of the Tunpu settlements were affected by the multiple synergies of natural environment, policy support, social-economic factors and cultural customs. Among them, policy factors and cultural factors were the dominant factors in the space diversity characteristics of the Tunpu settlements. By analyzing the space diversity law and its driving factors of the Tunpu settlements, this study could provide an important scientific basis for the protection planning and management of traditional settlements.

    Abstract In some karst mountainous areas, with the urban expansion driven by rapid urbanization, a large number of natural mountains that were not suitable for development and construction were embedded into the urban built environment, forming urban remnant mountains(URMs). In this study, we conducted a indicator system to explore the relationship between morphological characteristics of URM and its plant species diversity. The results showed that: (i) The two boundary plane morphological indicators of URMs were significantly associated with its plant species α and β diversity; among the overall morphological indicators, mountain form factor (MFF) was significantly associated with plant species α and β diversity, mountain size coefficient (MSC) was negatively related to Margalef (R) index, and mountain volume density (MVD) had no significant relationship with plant diversity. Additionally, surface morphological indicators were significantly negatively correlated with the Pielou (Jgi) index, and positively correlated with Jaccard (Cj) and Sorenson (Cs) indices. (ii) There were also differences in the influence of morphological characteristic indicators of URMs on the plant species diversity of its different slope position and slope direction. Mountain shape index (MSI), mountain fractal dimension (MFD) and MFF had significant influence on plant species α and β diversity indices of different slope position and slope direction; All surface indicators of URMs morphological characteristics were significantly associated with plant species α and β diversity indices on the southern slope of URMs. (iii) The effects of URMs morphological indicators on plant diversity of different life forms were different, and the influence of herb plant diversity was more significant. (iiii) The multiple regression analysis showed that the URM morphological characteristic indicators could explain the difference of plant species α diversity among different URMs, while the interpretation of plant species β diversity among URMs was poor.
