基于遥感和GIS的中国土地潜力资源的研究

在对中国土地资源综合研究基础上，利用已有研究成果，借助ＧＩＳ工具，利用层次分析法，对中国土地地潜力资源进行了综合分析和评价，在评价基础上，对中国土地资源的耕地潜力、生产潜力、生产潜力总量、人口容量潜力及综合潜力的大小和空间展布特征进行分析。结论为：中国土地资源潜力很力，但时空分布不均，在开发利用中，应因地制宜，采取不同的开发、利用的战略方针，在保护好现有土地资源和合理科学利用的基础上，谨慎开发，以

The Research of Land Potential Resources in China Based on Remote Sensing & GIS

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.
