三峡库区移民安置区土地资源优化利用模式研究

三峡水库是我国特大型水利枢纽工程，三峡大坝蓄水后，大部分移民需后靠安置解决，导致土地利用压力加大。土地资源的优化利用研究对指导安置区农业持续发展以及生态环境建设等有重要的意义。基于移民安置区土地资源的特征和土地优化利用的原则，提出库区土地资源优化利用应突出效益主导、持续协调、产业协调、区域特色等4种模式，并针对当前安置区土地资源优化利用中的主要问题，提出了相应的优化利用对策。

Studies on the Optimal Utilization Models of Land Resources in the Immigrant Settlement Region of the Three Gorges Reservoir Area

Three-Gorges reservoir is one of the biggest water conservancy and control projects in the world.As the big dam of the Three Gorges Reservoir Area starts to reserve water and a majority of local habitants need to be settled down backward,the pressure on the exploitation of the land is becoming higher and higher.The studies on the optimal utilization of land resources is of great value and significance to instructing agricultural sustaining development in the immigrant settlement region and ecological construction.Based on the characteristics of the land resources and the principles of optimal using land resources,it is suggested that close attention should be paid on these areas such as benefit leading,sustaining adjustment,industrial restructuring and regional difference in optimal utilization of land resources.In accordance with the problems of optimal utilization of land resources in local settlement region,the corresponding countermeasures in optimizing the use of the land resources are proposed.
