摘要
以宁夏回族自治区为研究区,选取地形、地表覆被、气候、水文、土壤适宜性作为评价指标,构建了宁夏地区人居环境自然适宜性模型,定量评价人居环境自然适宜程度,剖析各类型区的适宜性和限制性。研究表明:①宁夏地区人居环境自然适宜性空间分异明显,存在着较强的聚集性;②2020年宁夏地区人居环境自然适宜性指数介于22.79~80.67,整个地区以临界适宜和一般适宜为主。
This study established a human settlement natural environment evaluation system for Ningxia,which included five single factor suitability models and a comprehensive model of the human settlement natural environment.The five single factors included terrain,surface cover,climate,hydrology and soil suitability.This paper quantitatively evaluated the natural suitability of human settlements,analyzed the suitability and limitations of various types of areas.The research showed that:①The natural suitability of human settlements in Ningxia had obvious spatial differences,There was a strong aggregation.②In 2020,the natural suitability index of human settlements in Ningxia was between 22.79 and 80.67.The whole area was mainly critically suitable and generally suitable.
