The Research of Land Potential Resources in China Based on Remote Sensing & GIS
基于遥感和GIS的中国土地潜力资源的研究

On the basis of the results of studying the land resources, the land potential resources of China were analyzed and evaluated with Geographic Information System (GIS) technology and Analytic Hierarchy Process (AHP) method. The quantity and distribution characteristics of farmland potential, land productivity potential, land productivity gross potential, land people capacity potential and land comprehensive potential were then analyzed and studied. The conclusions are that the land potential resources in China is tremendous, but the distribution of these potential resources is unbalanced. Therefore, in the development and use of potential land resources, different strategies and policies should be used in difference places. On the basis of protecting and scientifically using the current land resources, the exploitation and utilization of potential land resources in the future should be conducted with the viewpoints of sustainable development.
