“…Natural elements are the basis of settlements layout development, and humanistic elements are also the pillar of settlements development (Hansen et al, 2020;Talukdar et al, 2020;Da Costa et al, 2018;Torretta et al, 2020). However, at present, most of the researches on the suitability settlements focus on the natural suitability of settlements (Hu et al, 2020), and consider the humanistic indicator of settlements (Zhang et al, 2018;Liu et al, 2020;Fuller et al, 2018;Omar and Raheem, 2016;Tezer et al, 2020;Cui et al, 2017;Yan et al, 2017). Therefore, based on the previous studies on natural suitability, this paper adds humanistic indicator to comprehensively evaluate suitability of sustainable development for settlements, to provide a new way for the study of suitability of settlements research perspective, enrich the evaluation index system.…”

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.

“…In this way, it is easier to regulate the utilization of groundwater in the study site. Shouguang City, located in the middle of the Shandong Peninsula, is the largest vegetable farming base in China (Hu et al, 2020(Hu et al, , 2021. Ideally, groundwater is an essential source of drinking water and irrigation, which plays an irreplaceable role in the economic development of Shouguang (Yang et al, 2021).…”

Groundwater is an essential nonrenewable resource for agricultural activities. In this study, groundwater samples were collected from the Shouguang area, and the level of groundwater contamination was investigated by measuring the NO3−, SO42−, F−, Cl−, Ca2+, Mg2+, total dissolved solids (TDS) and chemical oxygen demand (COD). Exploratory data analysis was employed initially to study the hydrochemical characteristics and the sources of pollutants. Finally, the groundwater quality was measured using principal component analysis, entropy weight and complex correlation coefficient methods. As a common observation, the groundwater in the Shouguang area is slightly alkaline, so Ca2+, Mg2+ and NO3− acted as predominant pollutants. These contaminants originated from the excessive use of chemical fertilizers and large‐scale sewage irrigation. Second, perennial overexploitation of groundwater in Shouguang led to the generation of funnels and led to seawater intrusion. As a result, Cl− and TDS in the water samples collected from the north Shouguang area exceeded the regulatory guideline value, which indicates the risk of land salinization. However, the measured concentrations of SO42−, F− and COD were within the normal range. This confirms the minimal contribution of industries to groundwater pollution. East of the Ni River the groundwater is severely polluted, and the detected concentrations of pollutants are far beyond the standard limit and pose a potential risk to human health. Therefore, protection and treatment are urgently needed.

“…This exceeds Greater London's population density of 5726 people per square kilometer and is similar to Tokyo's population density of 7846 people per square kilometer, but it is lower than New York City's population density of 11,002 people per square kilometer [30][31][32]. Wuhan's extremely high population density is accompanied by economic development and the improvement of the regional urbanization level, leading to continuous urban renewal and large-scale urban construction [33][34][35].…”

The development and utilization of land in the main urban area have significantly impacted the stability of the regional geological environment through various means, such as increased load and subway construction, primarily manifested as rock and soil mass deformation leading to geological hazards. Therefore, it is worth exploring how to reduce the occurrence of karst ground subsidence (KGS) through reasonable land development and control measures in the main urban areas with large-scale developments of buried karst formations. This study focuses on the main urban area of Wuhan City. An evaluation model for KGS was constructed using the analytic hierarchy process (AHP) and comprehensive index evaluation method by analyzing the geological conditions that affect KGS. The susceptibility zoning of KGS was obtained with GIS spatial analysis technology. The results show that the susceptible areas can be divided into extreme, high, medium, and weak susceptibility, accounting for 4.93%, 15.30%, 33.21%, and 46.56%, respectively, which are consistent with the distribution density of past KSGs. Furthermore, by selecting the subway construction as a human activity type, it indirectly discusses the influence of land development intensity on KGS. The results show that past KSGs are mainly concentrated in areas with high engineering construction density and significant land development intensity. Based on the above, strategies for regional land development and prevention and control of KGSs are proposed.
