| 摘 要： | 根据DPSIR模型的原理,从驱动力、压力、状态、影响及响应5个方面建立衡阳市生态系统健康评价指标体系,应用层次分析法赋予指标权重,采用模糊数学方法构建评价模型,对衡阳市2004—2008年生态系统健康状况进行了实证评价研究。结果表明衡阳市的总体健康状况2004年处于病态状况,2005—2007年处于不健康状态,2008年处于亚健康状态,衡阳城市生态系统整体健康状况趋于好转。

| Abstract: | Based on DPSIR model, A evaluation index of city eco-system health was established, which inclued driving force, pressure,state,and related response five aspects. The weights of the indice are given by analytic hierarchy process and the eval- uation model was build using the fuzzy mathematics method. The value of ecosystem health index was caculated during 2004-- 2008 in hengyang. The results showed that the overall health of Hengyang City was pathological in 2004, unhealthy during 2005--2007 and sub-health state in 2008. |
