长江上游洋派河小流域生态修复研究
摘要
通过野外全面调查、样点调查、样方调查和室内测试分析
对云南长江上游洋派河小流域退化生态系统的人为诱导修复进行了研究。结果显示
有自然恢复条件的退化生态系统
经过4年人为参与的不同措施修复
小流域复合生态系统的组成要素、生态系统结构和功能都得到一定程度改善。生态系统类型增加
较稳定和趋于正向进展演替生态系统的水平分布面积扩大
人为重点修复生态系统的立体垂直结构逐渐显现
生物多样性和生物量增加
土壤理化特性得到改良
土壤流失减轻
森林覆被率提高
修复效果明显。
Abstract
The ecological restoration of Yangpaihe watershed in Yangtze upper-reaches is researched with the methods of overall inventory
sample plot survey and indoor room analysis. The results show that the ecological elements
structures and functions get better by the measures of the man made restorations for the degenerated ecologies. The ecological types are increased
the area of the stable ecological types of water and soil conservation forests
terraces
enclosures of the hillside for regeneration is added whiling the area of the fragile ones of steep slope fields and waste lands is decreased. In general
the soil properties of physical and chemical are improved
the water and soil losses are under control and the biodiversity is in richer.
