Evaluation and spatial distribution pattern analysis of livable environment suitability in Cangzhou
Scientific evaluation of human settlements suitablity and its spatial distribution pattern is crucial for coordinating regional sustainable development. Addressing the issue of predominanly single-scale comprehensive evaluations, this study introduces a comprehensive evaluation index system to guide multi-level, multi-dimensional assessments.Cangzhou, Hebei Province, serves as the research area. The evaluation index system includes three natural element indicators and four human element indicators. Natural indicators encompass vegetation, temperature-humidity index, and hydrology indices, while human indicators include air quality, night light, traffic access, and public service indices. An index system that comprehensively reflected the suitability of human settlements was designed, and the weight of each index was determined by entropy method. Then, the human settlement environment index (HEI) was constructed, the single factor index and the comprehensive index were visualized, and the human settlement environment index of Cangzhou was statistically analyzed from the county and town areas. The natural, human, and comprehensive index of Cangzhou's human settlements are divided into four categories by natural breakpoint method: general suitable, moderately suitable, highly suitable, and highly suitable areas. The suitability of human settlements in Cangzhou was evaluated from the perspectives of county level and town level, single factor, sub-dimension and global perspective, and the spatial differentiation pattern was revealed by using GIS statistical analysis method, and the correlation between population distribution, regional gross product and human settlements quality was discussed. The results show that: (1) According to the comprehensive index of human settlement environment quality in Cangzhou, natural suitability is relatively high. Cultural suitability is higher in Cangzhou but lower in the surrounding rural areas. The highest comprehensive suitability is in Qingxian County in the north, the central municipal district, and Botou City in the southwest. Conversely, the lowest suitability is in Yanshan and Haixing Counties in the east, and Renqiu and Suning Counties in the west, indicating lower overall suitability in the east and west and higher in the middle. The distribution of human settlements suitability in Huanghua City and Renqiu City shows imbalance according to the classification map of human settlements suitability in each county and township. (2) Township-level settlement suitability in Cangzhou shows significant spatial autocorrelation and clustering effects among neighboring townships. (3) Comprehensive settlement suitability correlates positively with population distribution, while natural suitability shows a negative correlation with population density and per capita GDP. Human settlement suitability aligns closely with population distribution, highlighting areas for development in Cangzhou's settlement layout in 2020 based on high HEI locations.
