    Abstract The Beijing(Jing)-Tianjin(Jin)-Hebei(Ji) (JJJ) urban agglomeration is one of the three major urban agglomeration in China, which plays an important strategic role in China’s regional development pattern. Based on the concern of inter-relationship within urban agglomeration, this paper creatively proposed a comprehensive gravity-Gram Schmidt Orthogonalization coupling model (CG-GSO) to quantitatively measure the urbanization development level at different regional scales. Compared with the information entropy method, the CG-GSO model was more reliable and fairer in evaluating the urbanization development of an urban agglomeration in the inter-annual dimension. We used the obstacle factor model to find out important ways to realize sustainable development at different regional scales. According to the trends from 2003 to 2017, the urbanization development levels were predicted by using the gray forecast model at different regional scales during 2018–2030. There was an upward trend in urbanization development at different regional scales. Compared with the internal single regions, a high starting and slow developing trend was in the urban agglomeration. In Beijing, the obstacle factors in urbanization development were in the demographic, social and eco-environmental subsystems. However, the obstacle factors were in the economic, eco-environmental and social subsystems in Tianjin, Hebei and JJJ urban agglomeration. The forecast results showed that urbanization development was going strong in internal regions from 2018 to 2030, while the overall urbanization development was slow in urban agglomeration. Urbanization development should focus on labor redistribution, weakening the boundary on social welfare, improving the efficiency of economic development and paying attention to protecting eco-environment for taking the sustainable development road in the JJJ urban agglomeration.

    Abstract Urban agglomeration is an important geospatial unit for achieving SDGs. At the same time, air environment is the key to ensure the healthy life and safe production of mankind. Despite growing concern over the sustainable development in urban agglomeration, there is still little discussion on the coordination between air environment and urbanization within urban agglomeration. Here, the coupling evaluation index system was constructed from four urbanization aspects and three air environment aspects. Based on the real nonlinear internal relationship, the CG-GSO model was used to quantify the urbanization development level in the Beijing(Jing)-Tianjin(Jin)-Hebei(Ji) urban agglomeration from 2003 to 2017. It showed that social urbanization and economic urbanization were mainly the driving factors in single regions, and the urbanization development levels were rising steadily in single regions and urban agglomeration. In the air environment subsystem, the driving factors mainly existed in the air environment pressure and control, while the dynamic trends were fluctuating upward. On urbanization, urban agglomeration was conductive to the realization of regional sustainable development; but on air environment, the result was the opposite. In addition, the dynamic trend of the coupling coordination degree was far worse in urban agglomeration than in single regions. The scenarios were predicted and analyzed on barely and superiorly balanced development during different periods, and strong national pollution control policy was the key to promote the coordinated development between urbanization and air environment in the Beijing(Jing)-Tianjin(Jin)-Hebei(Ji) urban agglomeration. This study provides reference for sustainable development in urban agglomerations.

    Abstract Coal is a vital resource in China. With limited coal and the deteriorating eco-environment, it is consensus to take the sustainable development road in coal power exploitation regions. Taking Xilingol League, Inner Mongolia as an example, based on the cascade framework constituted by the “Driver - Pressure - State - Impact - Response” (DPSIR) model, this paper aimed to analyze the ecological carrying capacity at the league (city) scale and at the banner (county) scale contrastively. It found that the overall change trend was a wide “V” type at the league (city) scale. Moreover, the ecological carrying capacity at the banner (county) scale showed that the north was superior to the central and south in 2005, 2011 and 2018. The principal component analysis (PCA) approach had been adopted to analyze the driving factors. Driving factors were economic development and coal and electricity development at the league (city) scale, as well as resource supply and urbanization development at the banner (county) scale. At the league (city) scale, the economic benefits of industrial development had improved people’s living standards, and part of the funds could be used in the investment in ecological restoration, thus improving the ecological carrying capacity; at the banner (county) scale, most counties were still coal-dependent areas, and the number of resources had a more significant impact on the ecological carrying capacity. This study provided ideas for sustainable development in energy exploitation regions at different scales.

    Abstract The regional sustainable development level (SDL), sustainability of regional development (SRD) and system coordination (SC) make up the triangular truss of regional sustainable development assessment, but it is debated how should traditional practice best weight and calculate the whole sustainable development system level. The Bohai Rim, covering three provinces and two municipalities in China, lies in a region that is sensitive to profound conflict between socioeconomic development and environment pollution in the process of sustainable development. Considering the defects of traditional models and the multidimensionality of regional sustainability issues, we proposed an integrated model of nonlinear principal component analysis and Gram Schmidt orthogonalization and presented a novel regional sustainable development assessment method and framework from three perspectives for the society–economy–environment system of the Bohai Rim region. The results show that: (a) the integration of nonlinear principal component analysis and Gram Schmidt orthogonalization can well remedy the defects of traditional methods and provide a more objective conceptual framework; (b) the sustainability of regional development and system coordination models graphically demonstrate the essence and connotation of a dynamic sustainable development system; (c) the empirical study demonstrated that the Bohai Rim region has experienced a distinct development period in which the SRD experienced a steady decline and the SDL and SC generally increased; (d) the coordination ability can be improved by a decline in the environmental sustainability, which reveals the importance of environment subsystem optimization; and (e) the weight distribution of variables demonstrates that the most significant factors affecting sustainable development are the indicators from the dimensions of people's standard of living, economic structure and environmental pollution. This study enriches the sustainable development assessment theory and methodology, and lays the foundation for further sustainable development research in the Bohai Rim region.

    Abstract The development of large coal power plants is often accompanied by environmental pollution, thereby influencing the lives of the surrounding residents, resulting in a “not-in-my-backyard” effect and associated social injustice. To mitigate these influences, we conducted field research and questionnaire surveys with individuals living in areas around the Xilinhot coal power plant to explore their cognitive and behavioral psychological changes in response to the environmental risks of the coal power plant and the factors influencing such changes. A “cognition-perception-behavior” model was constructed for residents coping with the ecological environment influenced by the development of the coal power plant. Cognition of eco-environmental risks had a significant effect on the perception of eco-environmental risks which, in turn, significantly promoted the adoption of adaptive behaviors. Residents had a strong cognition and perception of eco-environmental risks but an extremely low likelihood of adopting relevant adaptive behaviors. Thus, affective responses can increase the residents’ cognition and perception of eco-environmental risks, and the communication of risk information can help them evaluate eco-environmental risks rationally.

    Abstract Ongoing success throughout regional development is contingent on maintaining the function, quality and harmony progress in society, economy and environment domains, so exploring the interaction and relation among them should be considerable significant. The model by coupling principal component analysis and vector autoregressive, which relate the aggregated values and dynamic analysis among factors, is proposed to achieve the qualitative and quantitative analysis of interaction and relation among society, economy and environment subsystem, providing a framework to conceptualize the influences among their changes and simulate the future scenarios in the Bohai Rim region. The impulse response analysis and variance decomposition of vector autoregressive method, in particular, permit dynamic interaction between every two systems and display clear decomposition of contribution for each change, respectively. This study results show that: there is a virtuous circle of promotion between economic growth and social progress no matter which is regarded as the endogenous variable during the study period, and yet the negative effect to environmental changes had been produced; what the improvement of social and environmental situation need most might be advancing its own progress; it is also reflected that the entire complicated system walk on the path of unsustainable development due to the evident disequilibrium of three subsystems; and the scenario analysis results obviously tell that in order to attain coordinated development, the annual growth rate of 12% to 16% of overall environmental level should be anticipated along with 8% of social and economic level improve. The study guide future possibilities for relatively more harmonious interconnections among social, economic and the environmental development.

    Abstract The well-run structure, function and dynamics of complex regional sustainability system are critical for maintaining regional sustainability stability, so exploring the interaction characteristics and development pattern of the system should be considerably significant. Based on the new comprehensive index system of sustainability system, the indices of social, economic and eco-environmental dimensions and nine thematic indices are firstly presented for BHR (Bohai Rim) and YRD (Yangtze River) regions during the period 2001–2010, and then the regional sustainability changes are further tracked by regional sustainability index (RSI) and regional coordination index (RCI). Furthermore, we mainly focus on the dynamic interaction characteristics and propose green development index (GDI) to reflect the development pattern of BHR and YRD from the perspective of taking all indicators into account. The study results show that: the average annual growth rates of the indices of social, economic and eco-environmental dimensions of the BHR region are 10.00%, 19.11% and 0.37% during the study period, while the ones of YRD region are 7.32%, 20.25% and 0.46%, respectively, demonstrating that economic progress is the fastest-improving pillar for RSI of the two regions; the standard deviations of the indices of three dimensions that can construct a triangle diagram and the amount of that failed to construct are both decreasing from 2001 to 2012, showing that the RCI of two regions have made some progresses; BHR have stayed in some positions where eco-environmental level gradually decreases (from 0.50 to 0.45) with the progression of socioeconomic situations (from 0.20 to 0.50), while BHR in a position where eco-environmental level gradually increases (from 0.53 to 0.57) with the progression of socioeconomic situations (from 0.25 to 0.55), revealing dynamic interaction characteristics, and then in their evolution trajectories, YRD has been principally at the intermediate sustainable development stage while BHR always at the potentially unsustainable one; the green social or economic development degree, associated with the uneven resource utilization and eco-environment occupancy among provinces, should contribute most to regional development pattern. The study guides a direction where the policy makers need to improve in regional sustainability management.

    Abstract Understanding the current evolution and drivers behind regional sectors’ growing energy-related CO2 emissions is critical for developing global climate policies and providing insights into how our emerging economies can target lower emissions in the future. We propose estimation and explanation models of sectors’ energy-related CO2 emissions and present a novel scenario design, all of which are originally applied in the CO2 emissions of the third economic growth pole of China (i.e., the Bohai Rim region) during period 2002–2011. We can therefore track the evolution and cumulative change therein, identifying key drivers of CO2 emissions change, and performing scenario analysis and projection. The estimation results show that CO2 emissions on both regional and provincial scales are maintaining an upward trend. On the whole, Shandong has the largest emissions in absolute terms, followed by Hebei, Liaoning, Tianjin and Beijing during this period, while all sectors’ CO2 emissions changes show a fluctuating trend. With the exception of the residential life sector, all sectors’ cumulative changes have increased over time. In addition, the explanation of the results prove that changes in per capita GDP and energy intensity are, respectively, the most significant stimulator and inhibitor for emissions’ current status. Similarly, whether changes in sectoral structure play a positive or negative role depends on the increase or decrease in each sectors’ share in total GDP. Moreover, all sectors’ emissions in the Bohai Rim region will increase significantly regardless of the scenario. We can therefore achieve our 2020 CO2 mitigation targets across all sectors only under a scenario whose annual average GDP growth rates and energy consumption are both set by the “12th Five-Year Plan.”

    Abstract Most cities or leagues in Inner Mongolia are the result of resource-based industrialization processes and animal husbandry development, leading to a heterogeneous composition and configuration of urban areas seldom guided by proper urban ecological landscape regulation policies. In this paper, we chose Xilingol as a case study, and put forward novel ecological landscape regulation approaches based on ecosystem services (ES) for achieving sustainable development in it. An urban ES simulation model and an urban classification model were used to assess the change of ES and to guide the future urban ecological landscape regulation. The results showed a rapid land use change in different subsystems of Xilingol from 2008 to 2013, providing relative values of each type of land per unit in three subsystems (core urban area, suburb and rural), and detected the change of ES in three subsystems and the change of ES per capita in the whole administrative urban area. We suggest that (a) long-term, stable, and ecosystem-services-based land use policies and urban ecological landscape regulation approaches are needed; and (b) highlight an urban ecological landscape regulation approach covering economic, social and natural dimensions for achieving sustainable development.

    Abstract A key step towards the restoration of heavily disturbed fragile coastal wetland ecosystems is determining the composition and characteristics of the plant communities involved. This study determined and characterized the community of higher plants in the Chenier wetland of Bohai Bay using a combination of field surveys, quadrat approaches, and multivariate statistical analyses. This community was then compared to other adjacent wetlands (Tianjin, Qinhuangdao, Laizhouwan, Jiaozhouwan, and Yellow River Delta wetland) located near the Huanghai and Bohai Seas using principal coordinate analysis (PCoA). Results showed a total of 56 higher plant species belonging to 52 genera from 20 families in Chenier wetland, the majority of which were dicotyledons. Single-species families were predominant, while larger families, including Gramineae, Compositae, Leguminosae, and Chenopodiaceae contained a higher number of species (each⩾6 species). Cosmopolitan species were also dominant with apparent intrazonality. Abundance (number of species) of temperate species was twice that of tropical taxa. Species number of perennial herbs, such as Gramineae and Compositae, was generally higher. Plant diversity in the Chenier wetland, based on the Shannon-Wiener index, was observed to be between the Qinhuangdao and Laizhouwan indices, while no significant difference was found in other wetlands using the Simpson index. Despite these slight differences in diversity, PCoA based on species abundance and composition of the wetland flora suggest that the Bohai Chenier community was highly similar to the coastal wetlands in Tianjin and Laizhouwan, further suggesting that these two wetlands could be important breeding grounds and resources for the restoration of the plant ecosystem in the Chenier wetland.
