摘要
生态修复是西部生态环境建设的有效途径,可利用生态系统自然演替能力,在人口密度较小的范围内开展封禁加补植的措施,加快西部植被恢复、生态重建和水土流失的控制。对生态修复的概念、内涵及需要研究的问题进行了讨论、提出了在黄土高原的植被建设应遵循植被的自然演替规律,采取"一退(退耕农田)、二封(封禁)、三改造(人工补植)"的方法,可以减少工作量,提高造林成活率,不大面积动土以防止土壤水分蒸发和造成新的水土流失。
Ecology restore is a effective way of ecological construction in the western of China. This can use the succession of ecological system areas in the areas of fewer people. The measures of close hillsides and replant is vegetation, ecological restore and soil and water conservation. The concept of ecology restore is discussed. Following measures could be taken: first,return cultivated land; second, close hillsides to livestock grazing and fuel gathering; third,artificial replant. Ecology restore can get twice the result with half the effort for ecological construction.
