| 摘 要： | 针对江苏九里湖塌陷湿地公园水体富营养化评价问题，于2018年春、夏、秋、冬4个季节对江苏九里湖塌陷公园内10个水质监测点进行水质监测，并选取TP、TN、CODMn、Chl.a、SD 5项水质指标，采用基于"压力-响应"思想构建二级模糊综合评价模型，结合熵权法对九里湖水质富营养化程度进行评价。评价结果表明，该评价模型具有合理性和客观性，江苏九里湖国家湿地公园水体富营养状态与季节变化相关性较强，各监测点富营养化等级处于中富营养与富营养级别。

| Abstract: | In the evaluation of eutrophication of water body in Jiuli Lake subsidence wetland park in Jiangsu Province, 10 water quality monitoring spots were under observation with TP, TN, CODMn, Chl.a, SD as the evaluation indicators during spring, summer, autumn and winter of 2018. And combining secondary fuzzy comprehensive evaluation model which based on the idea of "pressure-response" and entropy weight, the evaluation results proved the rationality and objectivity of the model applied to the evaluation of eutrophication of Jiulihu wetland in Jiangsu Province. The eutrophication status of Jiulihu wetland in Jiangsu Province was highly correlated with seasonal changes. Each monitoring spot was in the eutrophication level of the mesotrophic level and eutrophic level. |
