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

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.
