摘　　要：通过建立生态承载力评价指标体系,运用层次分析法计算指标权重,结合状态空间法建立生态承载力综合指数模型,对贵州省绥阳县生态承载力进行估算。将绥阳县生态承载力分为高承载力、中承载力、低承载力3个级别,针对绥阳县实际情况进行生态承载力综合评价分析,得出绥阳县生态承载力受人类活动影响较大,但生态承载力总体呈较好的态势,整个区域属中承载力,并从人为干预角度对全县的生态承载力情况做出评价并提出建议。The ecological carrying capacity of karst rocky desertification area was studied to provide the basis for the ecologic recovery and economic development in Karst rocky desertification area. The evaluation index system of ecological carrying ca-pacity of Suiyang County was established. The weight of various indicators were calculated by Analytic Hierarchy Process （AHP）. A comprehensive index model of ecological carrying capacity combined with state space method was used to estimate the ecological carrying capacity of Suiyang County. The results showed that ecological carrying of Suiyang County capacity could be divided into three levels：high carrying, medium carrying and low carrying. According to the comprehensive analysis of the ecological capacity, the results showed that human activities was the main factor influencing the ecological capacity of SuiYang County, but ecological carrying capacity had an upward tendency in general. The whole area belongs to medium carrying. The ecological carrying capacity of Suiyang County was analyzed and some advices were put forward with the view of human intervention.
