本研究於不同人工濕地統進行水質分析及水棲昆蟲相調查，研究結果發現，六個人工濕地採樣站間的水質參數與生物指標參數具顯著差異。將進行一年以上常態水棲昆蟲採樣的三個人工濕地系統之水質參數及生物指標參數進行相關性分析，探討以生物指標評估人工濕地水質的可行性。以河川污染指標、科級生物指標及夏農-威佛歧異度指標評估人工濕地系統水質，三者的優劣順序依序皆為港尾系統、嘉藥系統及蚵寮系統。利用三種方式評估水質的結果相似度高，因此應可參考現行利用生物指標評估溪流水質的方法，建立以生物指標評估人工濕地水質的模式，可使用科級生物指標或夏農-威佛歧異度指標，輔助化學分析方法進行水質整體許佔。 This study was conducted to suwey the parameters of water quality and collected the aquatic insects in various constructed wetlands. The results showed that the water quality and biotic index ofthe six constructed wetlands systems were significant difference. To use the river pollution index (RPI) to evaluate the water quality in the three regularly sampling constructed wetlands was the same as to use the Family-level biotic index and the Shannon-Weaver diversity index. The water quality ofthe three const™cted wetlands to fall into rank hom high to low was Gang-Wei system>Chna system>Chna system. To use the Family-level biotic index and Shannon-Weaver . diversity index to assess constructed wetland water quality were feasible. These methods could assist chemical analysis to assess the whole water quality.
