摘　　要：提出了退化生态系统修复的理论依据,并根据生态系统的受损程度,提出了修复步骤和可能的生态系统修复结果。对长江上游有自然恢复条件的洋派河小流域退化生态系统修复进行了分析,结果显示,经过4年人为诱导修复,小流域复合生态系统的生态系统类型增加,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。The theory, procedure and possible results of ecological restoration are put forward. The ecological restoration in Yangtze upper-reaches is researched. 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, and the area of the stable ecological types is added while the area of the fragile ones 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.
