摘要
Peatlands are unique type of wetland with a special hydrological, soil and vegetation characteristics. It sup-ports its own values and functions in water conservation , L)iodiversity conservation and carbon storage etc. The purpose of this study aims to identify main causes of the peatland degradation and demonstrate a restoration project of high altitude peatlands in Ruoergai Plateau in order to protect regional biodiversity. The study made some trials integrated, some fieldsurveys and restoration approaches to protect peatland biodiversity. The results showed that the drainage of peatlands in 1970s of 20th century greatly made the peat drained and alterecl peatland hydrology afterwards, soil became desiccated and water capacity decreased, and local inverse vegetation succession and ecological deterioration are apparent；dam-ming and blocking canals have been taken to restore hydrological features of wetlands. The engineering restoration was proved workable and achieved expected results.
