| 摘要: |
| 若尔盖草原湿地位于青藏高原东部，对其科学合理地分区是制定生态保护修复方案的基础。本研究以若尔盖草原湿地为研究区域，基于多维数据对其生态系统质量、生态系统服务功能重要性、生态脆弱性、生态保护重要性等6个方面进行评估，诊断出若尔盖草原湿地各流域关键生态问题。结合河流的分布状况、水流流向特征以及出水口具体位置等来综合研判并识别生态修复优先区，以“流域特征+生态功能+生态问题”为原则划分生态修复单元并提出生态修复模式和目标。研究结果表明：(1)研究区生态系统质量整体上处于中等-良好水平；生态系统服务功能重要；生态脆弱；生态保护重要性等级高；生态恢复能力一般；生态景观格局存在断裂点,景观破碎度高，土地胁迫加重。(2)主要生态问题基本沿河流分布，生态问题集中区为生态修复优先区。(3)将若尔盖草原湿地划分为6个生态修复分区，并根据生态修复分区内各类生态问题的严重程度和分布情况将其划分为6个生态修复单元。本研究中的若尔盖草原湿地生态修复分区及修复单元划分经验，对于高寒湿地实施山水工程具有重要意义，可为高寒湿地开展生态保护修复工程提供借鉴和参考。 |

| 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 comprehensively 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 environmental 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 units.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. |
