【摘要】：借助GIS软件平台,以1km×1km栅格为基本单元,选取8个主要影响因子,定量评估湖南省人居环境适宜性并进行区域划分,进而探讨湖南省人居环境适宜性与人口分布的关系.研究表明:(1)湖南省人居环境适宜性指数区间为4.75～9.33之间,中值为7.04,总体适宜性较好.(2)从空间结构来看,湖南省人居环境适宜性指数具有明显的空间差异,即湘北洞庭湖带和湘中湘江带是湖南省人居环境高度适宜集聚区,湘西北、湘西南和湘东南边缘区是人居环境不适宜区.(3)根据适宜性聚类分析,湖南省人居环境高度适宜区的县市(州)有48个,一般适宜区的县市(州)有42个,不适宜区的县市(州)有11个.(4)湖南省人居环境适宜性与人口分布之间具有很强的相关性,曲线拟合度高达0.91.不同发展水平区域人居环境适宜性指数与人口密度相关性有较大差异.
[Abstract]:Taking 1km 脳 1km grid as the basic unit, eight main influencing factors were selected to quantitatively evaluate and divide the human settlements environment in Hunan Province, and then to explore the relationship between the habitat suitability and population distribution in Hunan Province. The results show that the index range of human settlements suitability in Hunan Province is between 4.75 and 9.33, the median is 7.04, and the overall suitability is good. (2) from the spatial structure point of view, there are obvious spatial differences in the index of human settlements suitability in Hunan Province. In other words, Dongting Lake Zone and Xiangjiang River Zone in North Hunan Province are highly suitable for human settlement environment in Hunan Province, while Northwest Hunan Province, Southwest Hunan and Southeast Hunan marginal region are not suitable for human settlement environment. There are 48 counties (prefectures) in Hunan Province, 42 counties (prefectures) in general and 11 counties (prefectures) in unsuitable areas) there is a strong correlation between habitat environmental suitability and population distribution in Hunan Province. The fitting degree of the curve is as high as 0.91. There are great differences between the index of habitat suitability and the population density in different development level regions.
