西藏玛旁雍错国家级湿地自然保护区草地生态修复的探讨--以普兰县披碱草试种为例

Discussion on Ecological Restoration of Grassland in Lake Manasarovar National Wetland Reserve:A Case Study of Elymus dahuricus Turcz.in Pulan County

玛旁雍错国家级湿地自然保护区地处西藏自治区西南部的普兰县北部,其草地资源占总面积的33.78%,草地生态系统对于保护区生态功能的发挥起着至关重要的作用。然而,目前保护区内草地退化严重,亟待修复。为探讨保护区草地生态修复方向,以普兰县披碱草试种为例,分析在保护区内草地退化区域种植披碱草所面临的问题,并结合已有的研究成果,对保护区退化草地生态修复方向提出建议。

Lake Manasarovar National Wetland Nature Reserve is located in the north of Pulan County which is southwest of Tibet.Grassland resources account for 33.78%of the total area of this wetland reserve.Therefore,grassland ecosystem plays an very important role in the ecological function of protected areas.However,grassland degradation in the protected area is serious and needs to be repaired urgently.In order to explore the grassland ecological restoration direction in this protected areas,taking Elymus dahuricus Turcz.planted in Pulan County as an example,the problems of Elymus dahuricus Turcz.planted in degraded grassland area of protected area are analyzed in this paper.Finally,combined with the previous research results,the suggestion on ecological restoration direction of degraded grassland in protected areas is prospected.
