若尔盖草原湿地生态修复分区及修复单元划分研究
Study on Ecological Restoration Zoning and Restoration Unit Delineation of Ruoergai Grassland Wetland
摘要
Abstract
The Ruoergai Grassland Wetland is located in the eastern part of the Qinghai-Xizang Plateau,and its scientific and reasonable zoning is the basis for formulating ecological protection and restoration programs.In this study,Ruoergai Grassland Wetland was taken as the research area.Based on multi-dimensional data,six aspects including the ecosystem quality,the importance of ecosystem service function,ecological vulnerability and the importance of ecological protection were evaluated,and the key ecological problems in each basin of Ruoergai Grassland Wetland were diagnosed.Combined with the distribution of rivers,the characteristics of water flow direction and the specific location of outlets,the priority areas of ecological restoration were com-prehensively judged and identified.The ecological restoration units were divided according to the principle of'watershed characteristics+ecological functions+ecological problems',and the ecological restoration models and objectives were proposed.The research results show that:(1)The ecosystem quality of the study area is generally at a moderately good level,the ecosystem service function is important,the ecological environment is fragile,the importance of ecological protection is high,the ability of ecological restoration is general,the en-vironmental landscape pattern has fracture points,the landscape fragmentation is high,and the land stress is aggravated.(2)The main ecological problems are basically distributed along the rivers,and the ecological problem concentration areas are ecological restoration priority areas.(3)The Ruoergai Grassland Wetland is divided into 6 restoration zoning.According to the severity and distribution of various types of ecological problems in the Ruoergai Grassland Wetland restoration zoning,it is divided into 6 ecological restoration u-nits.The experience of Ruoergai Grassland Wetland ecological restoration zoning and restoration unit division in this study is of great significance for the implementation of mountains and waters engineering in alpine wetlands,and can provide reference for ecological protection and restoration projects in alpine wetlands.关键词
