摘要

近年由於全球氣候變遷，台灣地區乾旱及豪雨頻繁，且降雨有集中趨勢，對於水庫集水區之衝擊與影響，將比以往更為劇烈。同時，台灣地處於菲律賓與歐亞板塊的交界帶，各水庫集水區地形及地質結構原本不佳，歷經921地震後，其地質構造更加鬆動及脆弱，遇雨成災之情形更為頻繁，在水資源日益短缺的時代，如何有效改善現況並朝向永繽經營的目標邁進實為當前重要的課題，本文擬就國內目前水庫蓄水範圍及保護帶保育作概略介紹，以期一般人對水庫集水區保育工作有更深入的了解與認識，並期作為未來其他相關研究之參考依據。

Due to the global climate change, the frequency of drought and severe storm events is increasing in the Taiwan region. Furthermore, extreme rainfall tends to concentrate more in certain areas. These changes have caused greater than before impact on reservoirs, which are the major water supply source in Taiwan. Situated at the juncture of the Philippine and Eurasian plates, Taiwan has poor geomorphologic conditions and a weak geological structure at many reservoir sites. A major earthquake in 1999 further worsened these conditions; resulting in more frequent serious disasters after heavy rains. In an era of ever declining freshwater availability, how to effectively remedy the current situations and move toward a sustainable water resource management has become a very important task for the water authorities. In the present paper, the use of various conservation practices, such as buffer strips, in reservoir impounding and buffer zones in Taiwan will be described. The objective is to promote public awareness of conservation practices in reservoir watersheds and to provide a comprehensive reference for future studies.
