为了综合评价天然草原健康状况,以甘肃甘南藏族自治州为例,采用层次分析法和熵权法两种分析方法,选取13个草地生态系统健康指标,构建当地的“活力-组织机构力-恢复力-人文”体系草地评价系统,并结合样方数据和文献资料,分别评价了甘南州各县2001年、2004年、2007年、2009年的草地生态系统健康状况.结果表明：在指标层中,草地系统活力(B1)、组织机构力(B2)、恢复力(B3)和人文(B4)的权重分别为0.3731、0.3610、0.2168和0.0491；人文层次的“旅游产值占GNP比重”其权重仅为0.0491,说明人文社会对生态环境的影响力较小；植被状况的总权重值0.5507,说明了植被在牧区生态经济中处于非常重要的地位.甘南藏族自治州各县草地近10 a生态系统健康综合指数大多数在不健康域之间波动,并有向崩溃域方向发展的趋势.

The study used the system of ‘Vigor-Organization-Resilience-Humanity’with thirteen in-dictors of rangeland health assessment to evaluate the status of rangeland health in Gannan Prefecture in 2001,2004,2007 and 2009.The results showed that in the index layer,grassland system Vigor (B1 ),Organ-ization (B2),Resilience (B3)and Humanity (B4)weights were 0.373 1,0.361 0,0.216 8 and 0.049 1 re-spectively.The index of humanity was the proportion of tourist output value accounted for the GNP,and its weight was only 0.049 1,which indicated that humanity had smaller influence on the ecological environ-ment.The total weight of the vegetation value was 0.550 7,which indicated that vegetation protection was very important in area for ecology and economy.Ecosystem health index had fluctuated in unhealthy do-main in Gannan Prefecture in nearly ten years,and had the trend to collapse.The government should pay great attention and concern to the health of grassland ecosystem.
