| 中文摘要: |
| 生态系统健康评价是当前生态学研究领域的一个焦点和热点,目前尚没有统一的评价指标和方法。根据长寿湖区域自然人文特征和已有研究成果,建立了生态特征指标、功能作用指标和社会经济指标3个亚类、20个指标的生态系统健康评价体系,基于模糊层次分析(FAHP)的生态系统健康指数,对其生态健康进行了初步评价,得出2006年长寿湖生态系统健康指数为0.471。表明长寿湖生态系统处于亚健康状态,其主要原因在于长期受到上游垫江县、梁平县排放的工业污水污染及湖区内网栏养鱼的影响。 |

| Ecosystem health assessment is a focus and hot spots field of ecological research, there is no unified evaluation indicators and evaluation methods. First, according to the area physical, human features of the Changshou lake and existed research, We established ecosystem health evaluation system which has included three secondary indexes ： the ecological characteristics indicators, the function indicators and the socio - economic indicators, and has 20 indicators. Second, we assess the Changshou lake ecosystem with the ecosystem health index which based on the fuzzy AHP. The conclusions are as follows： in 2006, the Changshou lake ecosystem health index was 0. 471, it is showed that the ecosystem is in sub health, the mainly reasons is its upper reaches of the Di- anjiang county, Liangping county long - term discharge of industrial sewage and pollution of fencing fish. |
