摘要
对黄土丘陵沟壑区植被性质、土壤基质旱化、植被恢复和重建途径等理论及实践问题进行了详细论述 ,提出应采用集雨造林和径流林业技术 ,利用地带性林草种类 ,仿拟自然演替规律恢复和重建森林植被群落 ,构建“乔灌草”
In this paper theories and practice on characteristics of vegetation, drought of soil substrate, approaches to vegetation recovery and reconstruction on loess hill gully regions were described in detail. Thoughts and strategies on setting up a stable forest and grassland ecosystem with reasonable relocation of trees, shrubs and grasses, by adopting techniques on forestry with runoff and on assembling rainfall for afforestation, and utilizing local plant species as well as by imitating natural succession principles so that to reconstruction of forest vegetation communities, were put forward.
