摘　　要：采用基于AHP法的模糊评价模型,并通过最大特征根一致性检验、肯达尔一致性检验,全面评价了泰安市2001-2005年生态脆弱度变化情况,结果表明:二级指标中气候因素脆弱度、自然环境因素脆弱度、经济因素脆弱度逐年降低,社会因素脆弱度在较不脆弱的基础上波动,泰安市总生态脆弱度呈现逐年改良趋势;利用线性回归分析,确定自然环境因素是影响泰安市总脆弱度的主导因素,可根据其变化情况为预测泰安市生态脆弱度变化及指导生态建设提供科学依据。Fuzzy evaluation model based on analytic hierarchy process（AHP） which is verified by the consistency check of maximal Eigen value and Kendall Text was used to overall assess the change of ecological vulnerability of Tai＇an,Shandong Province in the period from 2001 to 2005.Results indicated that natural and environmental factor were confirmed as the dominating factor through linear regression analysis,which would provide scientific basis for predicting the change of ecological vulnerability as well as conducting ecological construction for the city.
