“…This large urban agglomeration contains 11 cities, seven of which were included in our studies. The findings on the characteristics of urban growth in the PRD could be informative for the construction of this world's largest metropolitan regions to achieve prosperous and sustainable development in this special and large urban agglomeration [42,43].…”

Contemporary urbanization in the Pearl River Delta (PRD) Urban Agglomeration is the epitome of China’s urbanization process as the PRD is the first fastest growing metropolitan region of China. Here, we mapped and quantified the spatiotemporal dynamics of urban expansion for seven major cities in the PRD between 1980 and 2015, using remotely sensed data integrated with landscape metrics, urban growth form, and rank clocks. Results showed that rapid land urbanization occurred in all the seven cities since the execution of reform and opening up, with the annual increase rate ranging from 8.1% to 11.3% among cities, suggesting a relatively equal level of urbanization within the PRD. Socioeconomic drivers underlying urban expansion in Guangzhou, Shenzhen, and Zhuhai can be characterized as “top–down” mechanisms led by the municipal government, while those in Foshan, Jiangmen, Dongguan, and Zhongshan are “bottom–up” ones from low–level administrative organizations. The trajectory of urban expansion in Shenzhen conformed to the diffusion–coalescence urban growth hypothesis in terms of temporal evolution of landscape metrics and urban growth types. This is related to the fact that Shenzhen, the first special economic zone established by the Chinese government, was the first mover of urbanization in China and functioned under the umbrella of a robust socialist market economy relative to a highly centralized planned economy for other cities. The changes of Shenzhen in rank order in terms of both urban population and urbanization area were the largest, exemplifying its evolution from a small fishing village to a metropolis. Furthermore, we found that moving up in the rank order in terms of land use efficiency of wealth creation over time for all cities was accompanied with rank clocking up of population per area (crowd). How to balance trade–offs between the benefits and costs of urbanization is the challenge faced by the urban agglomeration.

“…Identifying an appropriate indicator evaluation system is crucial for WECC, as it can determine whether the current water environment is sustainable and, if not, how to address its underlying problems. A hierarchical evaluation indicator system for WECC has been established in this paper based on the study of the relationship between environmental quality, water resources and social economy [30,31]. In this evaluation system, the overall target is represented by A and the overall goal is further divided into three system layers, including social subsystem (A 1 ), environmental subsystem (A 2 ), and economic subsystem (A 3 ).…”

“…According to the formulas (Equations (8)-(10)), it is necessary to acquire the grading criteria of all the evaluation factors. In this study, the grading criteria in Table 3 were obtained by classification standard from relevant research [28,31], or standards including "Eco-county, eco-city, and eco-province construction standards (Revised Draft)", "Urban residents domestic water consumption standard (GB/T 50331-2016)" and "General rule for planning urban drainage engineering (GB 50318-2017)".…”

China has experienced an unparalleled urbanization process in recent decades, which has dramatically changed the water environment. Quantification of the water environment carrying capacity (WECC) is crucial given its importance to sustainable development. Existing studies have typically focused on the overall WECC system and lacked analysis of its internal features. In this study, the concepts, calculations, and classifications of the WECC were further developed. Using Nanjing, China, as a case study, we developed a hierarchical evaluation indicator system including three system layers (social, environmental and economic subsystems). We applied the entropy weight and fuzzy comprehensive evaluation method to evaluate the temporal variation tendency of WECC, and explored the deep-seated problems stemming from urbanization. The results indicated that WECC in Nanjing was 0.3045–0.5302 during 2006–2017, thus approaching a moderate grade with a relatively slow growth rate. Social, environmental, and economic subsystems increased by 29.3%, 83.1%, and 97.2%, respectively. Overall, Nanjing had a solid foundation regarding its economic subsystem, but its social and environmental subsystems were under pressure. Factors such as slow population growth as well as reduced energy and water use intensity improved WECC, whereas factors such as increased population density and excessive water consumption blocked WECC. Practical suggestions were proposed to resolve the primary problems of the WECC under urbanization. This holistic approach is urgently needed to achieve water environmental sustainability, both for Nanjing and for other emerging cities.

“…To offer insights on suitability at a provincial scale, this study explored the case of Liaoning Province. In particular, we unpacked the impact of select natural elements on suitability, such as the relief degree of land surface (RDLS) index (Xiao et al, 2018b;Milanesi et al, 2015), the normalized difference vegetation index (NDVI) (Hou et al, 2016), the hydrology index (HI), the temperature and humidity index (THI) (Shao et al, 2020;Nouri et al, 2017), the land cover index (LCI) (Bikdeli, 2020;Wei et al, 2020;Shao et al, 2020), the nighttime light index (NLI), the land tra c accessibility index (LTAI), the air quality index (AQI) and other humanistic elements. Notably, we synthesized natural and humanistic suitability indicators to establish a comprehensive suitability index evaluation model for settlements based on the work we performed with ArcGIS10.2, ENVI5.0, spatial quantitative analysis, and our evaluation of the comprehensive suitability of sustainable development for settlements in Liaoning.…”

The comprehensive suitability of regional human settlements is of great significance to the development and spatial distribution of regional human settlements and regional social and economic development. In this study, based on the traditional evaluation of the natural suitability of the human settlements, this study adds humanistic indicators to comprehensively evaluate the suitability of the human settlements in Liaoning, China. In particular, we sought to uncover the spatial differentiation law of the comprehensive suitability of these settlements and its correlations with population density and GDP density, provide a theoretical basis for urban human settlements planning and governance. The main conclusions were as follows: (1) the natural suitability index in Liaoning Province presents the law of longitudinal spatial differentiation from northeast to southwest, which follows the direction of the mountains; (2) the highest to lowest humanistic suitability indexes were as follows: the central, eastern, and western regions; (3) the highest to lowest spatial differentiations of the comprehensive suitability of the human settlements were as follows: the central and coastal, eastern, and western regions;(4) the spatial distribution of population–economy density in Liaoning Province was basically consistent with the spatial distribution of the comprehensive suitability index of human settlements, The population economy is concentrated in the areas with the best and moderate human settlements. Ultimately, we found that the distributions of population–economy and human settlement suitability were relatively coordinated and that highly suitable land was already fully utilized.
