摘    要:进行流域的生态安全评价,对于改善流域的生态环境,维护区域的可持续发展具有重要的意义。本文选择自然生态环境状态指数、人文社会压力指数、环境破坏压力指数,构建了青海湖流域生态安全综合评价指数模型,提取了生态安全指标,对2000 年青海湖流域的生态安全进行了评价。结果表明,2000 年青海湖流域生态安全属于生态安全预警等级,流域生态安全面临着较为严峻的挑战。气候变化和人类活动对青海湖流域的生态环境产生的负效应,也因此会影响到区域的可持续发展,所以必须进行流域的综合治理,改善当地的生态环境。

关 键 词:青海湖流域;生态安全;评价指标

Abstract:The assessment of ecological security for watershed is signifi cant for the improvement of thewatershed environment and the sustainability of regional development. The paper assessed the ecologicalsecurity for Qinghai Lake watershed in 2000 after the Integrated Indices Model of Ecological Security(IIMES) for Qinghai Lake was built. The IIMES model was based on the three indices, the state indexof natural ecological environment, the human-culture-social stress index and the stress index of theenvironment prone to being destructed. The results showed that the ecological security for Qinghai LakeWatershed get scores at forewarning grade, which indicated that the ecological security for Qinghai LakeWatershed was facing a considerably challenge. More over, the climate changes and human activitiesmay sometimes have negative consequences to the environment of Qinghai Lake Watershed and regionalsustainable development. It was concluded that the integrative governance is urgently needed to improvethe regional ecological environment.
Keywords:Qinghai Lake watershed   ecological security   index of assessment
