摘    要:[目的]对大山包湿地生态系统脆弱性进行动态评价。[方法]运用层次分析法(AHP法)构建大山包湿地生态系统脆弱性评价指标体系,通过计算生态系统脆弱度,对2002~2008年大山包湿地生态系统脆弱性进行了动态评价。[结果]2002~2008年大山包湿地生态系统脆弱度分别为0.560 0、0.513 7、0.516 4、0.465 4、0.476 0、0.449 2、0.400 6,总体呈下降趋势,其生态系统脆弱性由中度脆弱性向轻度脆弱性转变,目前大山包湿地生态环境质量处于较好状态。[结论]该评价方法可以反映湿地生态系统脆弱性的发展变化过程,为湿地恢复与保护、湿地生态环境规划和管理提供依据。

关 键 词:大山包湿地  生态系统脆弱性  脆弱度  动态评价

Abstract:[Objective] The aim was to carry out dynamic assessment on ecosystem vulnerability in Dashanbao wetland.[Method] Evaluation index system of ecosystem fragility in Dashanbao wetland was constructed by using analytic hierarchy process(AHP),and dynamic assessment on ecosystem vulnerability in Dashanbao wetland from 2002 to 2008 was carried out based on vulnerable degree of ecosystem.[Result] The vulnerable degree of ecosystem in Dashanbao wetland from 2002 to 2008 was 0.560 0,0.513 7,0.516 4,0.465 4,0.476 0,0....
Keywords:Dashanbao wetland  Ecological vulnerability  Vulnerable degree  Dynamic assessment
