中文摘要 | 溪流生態棲地之評估方式繁多,隨著領域及地區之不同,往往會有不同的選擇;本研究以人為破壞較下游河溪少、生態復育潛力相對較豐富之上游野溪作為研究對象,選擇工程人員較易使用,且兼真物理性、化學性及生物性的量化指標一澳洲維多利亞省所發展之溪流狀況指數(Index of Stream Condition,ISC)評估模式為基準。其次,再以魚類作為水域生態之指標生物,針對ISC之水生物次指數作修正。最後,以本研究修正之方法針對臺灣各區域十條山區野溪進行評估,建立全台灣能適用、全年12個月之ISC評估指數。經現場調查分析,發現本研究比以往文獻更能反映出真實溪流狀況,且能評估完全未發現魚類時野溪之生態條件,是故本研究結果有助於臺灣山區野溪之生態復育工作。 |
英文摘要 | There are many kinds of ecological habitat assessments of streams due to the different regions and localities. This study targets at torrents, which have less contamination and more ecological potential restoration comparing with downstream ones, and chooses Index of Stream Condition (ISC), developed by the State of Victoria in Australia originally. ISC contained physical, chemical, and biological indexes which was easier to be used by engineers especially. The Aquatic Life Sub-index was modified by this research and was represented by fish species. Ten torrents in Taiwan were assessed by this modified method. The modified method could avoid rejecting the ecological conditions of torrents totally as no finding endemic fish species. The results of this study can be applied extensively to evaluate the conditions of fish habitats on torrents in Taiwan for ecological restoration projects. |
