基于遥感和GIS的中国土地资源生态环境质量同人口分布的关系研究

The Relations Analysis Between Ecological Environmental Quality of Chinese Land Resources and Population

基于用数字环境模型对中国土地资源生态环境质量评价的基础上，生成了中国土地资源生态环境综合评价图和人口密度分布图。首先分析了中国土地资源生态环境等级面积构成及分布状况，中国土地资源生态环境质量最好的地区全部分布在东南沿海和四川盆地地区，之后，用相关分析方法及关系曲线分析了中国土地资源生态环境质量同人口分布的关系，得出了土地资源生态环境质量指数同人口存在着实质性的相关关系，中国东南沿海和四川盆地地区是中国土地资源生态环境最好的地区，也是人口密度和土度资源利用程度最高的地区，而西北及青藏高原区是中国土地资源生态环境比较差的地区，也是人口密度比较低的地区。

Based on the evaluated ecological environmental quality of Chinese land resources with Digital Environmental Model (DEM), the comprehensive evaluated map of the ecological environmental quality of Chinese land resources and the map of population density were worked out. At first, the degree areas constitution and distribution condition of the ecological environmental quality of Chinese land resources were analyzed, the best land resources area of the ecological environmental quality is distributed in south east China; Then the relations between the ecological environmental quality of Chinese land resources and Chinese population distribution were analyzed with relative method and curves. The conclusions are that the substantive relations exist between the ecological environmental quality of Chinese land resources and population; the south east China is the best area of the ecological environmental quality of Chinesse land resources, this area has largest population density and highest used degree of land resources; the west north China is a poor area of the ecological environmental quality of Chinese land resources, this area has smaller population density and lower used degree of land resources.
