基于GIS的人居环境适宜性分区及其与人口分布的关系——以湖南省为例
Regionalization on the suitability of human settlement environment and its relationship with population distribution based on GIS——a case of Hunan Province
摘要
Abstract
Applying GIS software and taking 1km?km grid as basic unit, this article quantitatively evaluates and regionalizes the suitability of Hunan's human settlement environment (HSE) by selecting eight impact factors, such as elevation, gradient, slope aspect, land utilization, soil erosion degree, traffic accessibility, convenience of water resources utilization and THI. Furthermore, this article explores the relationship between the suitability of Hunan's HSE and its population distribution. The results show that; firstly, the suitability index of Hunan's HSE ranges from 4. 75 to 9. 33 with a median of 7.04, showing a good general suitability; secondly, from the view of spatial structure, the spatial variation of the suitability index of Hunan's HSE is distinct, with Dongting Lake area in the north of Hunan and Xiangjiang River basin in the middle being high-suitable areas, Northwestern and southwestern area and fringe areas of southeastern Hunan being low-suitabile areas, and other areas being general-suitable; thirdly, according to suitability cluster analysis, Hunan can be divided into three types of areas, i. e. the 48 counties of high suitability, 42 counties of general suitability and eleven counties of low suitability; fourthly, there is a strong and direct correlation between the suitability of HSE and population distribution in Hunan province, with the curve fitting up to 0. 91,however, the correlation coefficient of HSE suitability index and population density varies greatly among different areas because of the difference of their economic development.关键词
