摘牛沟小流域林草配置模式试验研究

The Experimental Research on the Matching Model of Forests and Grasses in Zainugou Small Watershcd

本文以摘牛沟为例,论述了小流域综合治理中林草配置的主导思想。在总体布局时应考虑多种制约因子,根据不同树、草种的生态适应性,筛选出不同立地条件的适宜树、草种及配置方式。并对半干旱黄土丘陵区小流域综合治理中的林草配置作了初步探讨。

Taking Zhainugou small watershed for example, this paper deals with the guiding thinking of the matching model of forests and grasses in the comprehensive control of small watershed. In an overall layout, the multiple constraints should be taken into account. The suitable trees and grass species and their matching models for various establishing conditions have been screened in accordance with the ecological adptabilily of various tree and grass species. Also, the paper discusses the matching of forests and grasses in the comprehensive control of small watersheds in the semiarid loessal hilly areas.
