摘要
坡地资源是我国土地资源的重要组成部分 ,其利用和保护对环境的稳定有着重要的影响。退耕还林在防止坡地水土流失 ,改善山区生态环境具有重要作用。国内外退耕还林模式有农林复合模式、等高植物篱笆技术、植物地梗及坡改梯等模式。其中 ,坡改梯和农林复合模式是目前国内普遍采用的方法 ,而等高植物篱笆技术与其他几种模式相比较是一种投资少 ,且保土、保肥、保水能力较为突出的新颖的防止坡地水土流失的技术 。
Slop land resource is an important part of land resource in China and its utilization and conservation deeply affect the stability of environment. It will playan important role on soil land water conservation and improvement of mountain area eco-environment for cultivated slop land to be returned to forest for instance: agroforestry method, contour hedgerow technique, plant barrier, terraced field and so on up till now. The models of agroforestry and terraced field are use extensile, but comparing with other methods of slop land utilization, contour hedgerow technique cost is less and its effect in soil water conservation and soil fertility sustaining is terrific. So it is necessary to be applied and popularized.
