摘　　要：合理的土地利用方式是三峡库区水土保持的重要基础,对确保三峡水库安全运行和库区生态安全具有重要作用。提出了库岸复合立体农业、有限顺坡耕作、水旱耕地交错布局三种典型土地利用模式,介绍了各种模式的结构和布局设计,分析了各种模式的基本原理及功能。三种模式投入低、操作方便并且高效、实用,适合三峡库区的地形地貌特征和社会经济环境。今后应加强对各种具有水土保持功能的土地利用方式的效应监测和适宜性评价,以筛选出适合三峡库区不同环境条件的土地利用模式。Rational land use is a basis for soil and water conservation in the Three Gorges Reservoir area which ensures the safe operation of the reservoir and the security of the regional eco-health.The paper puts forward three typical land use modes of tri-dimension eco-agriculture,slope land cultivation with cut down slope length and alternative layout between arid land and paddy fields,and introduces the structure and layout design of each mode,with analysis on basic principle and function of each mode.The three models are believed as low-cost,efficient,easy and adaptive to the natural and socio-economic settings of the Three Gorges Reservoir area.It suggests on strengthening the monitoring and evaluation on effect and suitability of land use with soil and water conservation functions for selecting a land use mode which is suitable to the different environmental conditions of the reservoir area.
