摘要

台灣以往所興建之水資源工程，大多以灌溉、給水、發電、防洪及觀光為目標，較少兼顧原有生態之維持，開發行為往往對生態環境造成較大之影響。湖山水庫工程計畫為國內首次兼顧生態保育之水資源工程，在工程計畫期間辦理多項生態保育措施，其內容包含生態系統調查研究、動植物保育、棲地補償及營造等。本研究以湖山水庫工程計畫為例，蒐集工程進行前（2003）至完工試營運期間（2017）環境監測資料（包含水質及棲地生態物種），以生物整合指數（IBI）、自然度（Indigenous species, I）、總豐富度指數、多樣性指數（H'）、均勻度指數等項目，評估水庫開發過程中所執行之生態保育措施，對該區域自然生態之補償及回饋效益。

Water resource engineering in Taiwan was conducted mostly for irrigation, water supply, power generation, flood control, and tourism. It ignored the maintenance of the original ecosystem and had serious impact on the ecological environment. The Hu-Shan Reservoir Engineering Project is the first time in Taiwan to consider both the ecosystem and engineering. A number of ecological conservation measures implemented in the project included the ecosystem investigation, flora and fauna conservation, habitat compensation, and habitat creation. As a case study, we collected the environmental monitoring data before and after the project (i.e. in 2003 and 2017), respectively. The data included water quality, habitat species, index of biotic integrity (IBI), indigenous species (I), Margalef's index, Shannon-Wiener's duversity index (H'), and evenness index. The ecological compensation and benefits in the region as a result of the ecological conservation measures were evaluated.
