摘　　要：科学评价人居环境适宜性并揭示其空间分布格局对协调区域可持续发展进程具有重要意义,目前已有研究多局限于单一尺度的综合评价,尚缺乏一套通用的评价指标体系以指导多层级多维度评估。本文选取沧州市为研究区,设计综合反映人居环境自然适宜性和人文适宜性的指标体系,构建人居环境质量综合指数,从县域–镇域不同层级、单因子–分维度–全局不同视角分别评估研究区的人居环境适宜性,对人口分布及经济与人居环境质量的相关性进行探讨。结果表明:(1)研究区人居环境自然适宜性总体舒适度较高;人文适宜性在市辖区较高,周边农村地区较低;综合适宜性最高的地方位于北部青县、中部市辖区和西南部的泊头市。(2)整体上,沧州市各乡镇人居环境适宜性存在显著的空间自相关关系,空间集聚效应较为显著,相邻乡镇之间存在相互影响。(3)人居环境综合适宜性与人口分布呈正相关,自然适宜性与人口密度、人均GDP呈负相关;人文适宜性与人口分布存在较高的协同性和相似的空间分布特征。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 s
