高屏溪是南部最重要的河川，政府為了解決高屏溪流域的河川污染，由高雄、屏東縣政府、經濟部水利署（第七河川局）及環保署等共同推動高屏溪污染整治。執行過程中包括對高屏溪流域內污染源稽查管制、上游水源區內養豬業者拆遷補償及進行高灘地溼地淨化工程等措施，不僅改善了長期河川水體污染之影響，同時也改變了河域生態環境。環保署為了瞭解高屏溪流域整治的生態效益，並瞭解現階段高屏溪水域生態之物種組成，特規劃本計畫以進行高屏溪與鳳山溪兩河川流域之生態調查，提供高屏溪流域進一步整治之生態參考。 本計畫生態調查項目包括植物性浮游生物、大型水生植物、底棲無脊椎、魚類及鳥類五大項。調查測站有高屏溪出海口、高屏溪大樹攔河堰、鳳山溪鳳山圳和?埔排水之匯流處，計有三個測站。 整體而言，高屏溪大樹攔河堰及出海口河段的浮游植物、底棲生物、魚類及鳥類物種都尚稱多元，雖然豐度都不高。高屏溪大樹攔河堰地區於旱季的魚類分佈分別以高身?魚為主要優勢魚種，而雨季高身?魚為次要優勢魚種，可視為目前河川水體的代表性指標物種；出海口地區於旱季及雨季則可分別以環球海鰶和大鱗鯔作為代表性指標物種。底棲生物部分於大樹攔河堰地區旱季以翡翠貽貝為代表性指標物種，雨季則以秀麗白蝦為代表性物種；出海口地區不論旱季及雨季均以翡翠貽貝為代表性指標物種。但由綜合藻屬指數(GI)及矽藻水質優養化指標(TDI)之分析，結果顯示攔河堰及鳳山圳此二河段仍處於優養化狀態。分析底棲生物群聚之K-dominance曲線，結果也顯示攔河堰河段仍受到環境衝擊；雖然出海口河段在雨季時情況較好，但在旱季時仍受到環境衝擊。因此，為掌握高屏溪河川整治的持續效益，並提供規劃整治的生態參考，仍應繼續進行生態調查。

This project, funded by the Environmental Protection Agency (EPA), is aiming to establish baseline data in the aquatic ecological aspects of the Kopin-Chi River and one of its tributary, Fong-shan irrigation channel. Coupled with the results of previous surveys related to its environments and ecology, attempts were also made to determine the dominant species of the river, and to evaluate the current status of the aquatic environments. In conclusion, the species compositions of phytoplankton, macrobenthos, fish and birds are varied and relatively diversified in the estuary and the Dashu damp area, though their abundances are rather limited; In the damp area, Varicorhinus alticorpus were significant dominant fish species and second dominant fish species during the dry and wet season, respectively, representing appropriate bio-indicators under current status of the river quality. In the estuary, Nematolosa come and Liza macrolepis are suggested as representative fish species for further bio-monitoring. For the macrobenthos community, Perna viridis and Exppalaemon modestus are dominant species in the damp area during the dry and wet season, respectively. In the estuary, Perna viridis is significantly dominant species either in the dry season or in the wet season. Based on the results of GI and TDI analyses, it appears that the river water in areas of the damp and the channel are still eutrophicated at present. Furthermore, the results of K-dominance analyses on the inveterbrate community also suggest that the river around the Dashu damp area is still under threatens of environmental impact. Similarly, the estuary area also shows environmental impact in the dry season, although it is less reflected during the wet season. All in all, the diversity of biotic communities along the Kopin-Chi River might explain the effect of pollution control in recent years, and further ecological monitoring is encouraged for a better understanding to the ecological recovery, providing an ecological basis for further pollution remedy sche
