| 摘 要： | 坡耕地是泥沙的主要策源地，虽然25°以上的坡耕地属于国家政策明令退耕区，但由于多数山地农业种植区存在耕地面积不足、农业燃料、饲料紧缺等问题，致使经济发展、农业生产生活与水土保持之间存在资源竞争的矛盾。基于此，提出采用等高固氮植物篱综合技术体系应对这一问题，在此基础上构建了适合小流域在进行25°以上坡耕地退耕还草后生态农业可持续发展的经济模式，并分析了该模式的效益，结果表明，采用植物篱技术进行退耕能够有效地促进山区生态农业的可持续发展。

| Abstract: | The sediments in the rivers mainly come from slope farmland. According to government policy, land steeper than 25° is banned to cultivate, but due to farmland, fuels and feed shortage, the resources competition among economic development, agricultural industry and water and soil conservation in these areas is very strong. This paper presented an integrated technique system called contour hedgerow, a sustainable development model of ecological agriculture was established in farmland steeper than 25°after returning to pasture in small watershed. The economic profit analysis of the model proved its effectiveness. |
