摘　　要：以贵州省黔南州为例,基于压力—状态—响应(PSR)模型,选取指标经济落后山区生态安全评价指标体系。采用熵权法对各指标赋值,熵权赋权克服了多指标评价中主观确定权重的不确定性。利用灰色关联方法计算黔南州的生态安全关联度,得出黔南州在改革开放30来不同年份生态安全指数,结果表明,自1979年以来,黔南州生态安全健康状况总体呈上升趋势。该方法具有一定的客观性,为经济落后山区生态安全评价提供更科学的依据。Take Guizhou Qiannan as an example, the Pressure-State-Response (PSR) model based on the selection of indicators, economic backwardness and evaluation index system of ecological security in mountainous areas. The entropy weight method is used to assign to each index,entropy weight to overcome the multi-index evaluation to determine the weight of subjective uncertainty. By using the grey correlation method to calculate the ecological security degree of Qiannan, the Southern Guizhou in the reform and opening up 30 years of ecological security index, results show that,since 1979, the state of Qiannan ecological security and health status of the overall upward trend. This method has a certain objectivity, provide a more scientific basis for the evaluation of ecological security in mountainous areas of backward economy.
