Sustainable land use is one of the essential objectives of exploitation, utilization and protection of the future land resources in Three Gorges Reservoir Area (TGRA) It is beneficial to revealing the structural characteristics of eco economic system of land use the situation among their subsystems to evaluate sustainable use of land resources aimed at its actual characteristics Furthermore, the scientific gist of making measures for strategic adjustment of land use and resettlement in the near future can be obtained by studying the ways and models of sustainable land use In this paper, the quantitative model for evaluation of sustainable land use is built Then based on the evaluation and analysis of sustainable land use potential and regional difference in TGRA, it is pointed out that the land use level as a whole are not only weakly sustainable, but also differs greatly in different regions Since there are a lot of impediment factors,therefore, the sticking point to make measures for land use is that the principles including adjustment measure to local conditions and guidance according to types must be complied, and the relationship among ecological rehabilitation,resettlement and economic development will be correctly disposed The main approach models inclucle four ways, namely,tree planting and of forestation, terracing slope land, optimizing structure and industrial breakthrough
