摘要
对影响云南干热河谷退化生态系统植被恢复的气候、水文、土壤、现存植被4个因子的特征进行了分析,据此得出在施行云南干热河谷退化生态系统植被恢复的过程中,必须考虑此4因子的综合影响。对云南干热河谷区采取人工植被恢复措施所遵循的原则是:宜乔则乔,宜灌则灌,宜草则草。
The characteristics of four aspect factors namely climate, hydrological conditions, soil and current vegetation which affecting the revegetation of Yunnan dry and hot valley were analyzed. It is concluded that during the course of revegetation, considering the comprehensive effects of these four factors is necessary. A critical principle for revegetation in the study area is matching the forest categories with the site conditions strictly, for those sites suitable for the growth of trees, shrubs and grasses, adopting tree species, shrub species and grass species respectively.
