我國前瞻基礎建設-水環境建設-加強水庫集水區保育治理計畫主要目標為減砂入庫與水質改善。本計畫對全國水庫管理提出前瞻性水質改善對策，工作項目主要面向：1.制訂本島水庫水質治理策略、2.制定離島水庫水質管理指標與機制、3.研析鳥類排遺對水庫水質影響、4.支援水庫水質污染削減技術及5.其他行政協助事項。水庫集水區污染調查結果顯示寶山水庫總磷主要污染源為上游端昌大橋至竹東圳之入流污染源，南化水庫則為集水區果園與農業活動，應加強削減氮磷營養源。分析環保署歷史分層水質數據及補充水庫分層採樣作業，提出「分層採樣規劃」、「水質監測項目規劃」及「監測數據評估方法」精進建議。水庫水質治理策略依水庫水質狀態及供水量為判定因子，建議近程目標以石門、鯉魚潭、曾文、烏山頭及南化水庫優先治理。綜整離島水庫指標適宜性分析、水庫水質管理法規等，離島水庫水質管理宜以飲用水水質安全為重點，可將COD或TOC、葉綠素a納入藻華與水質安全預警指標。鳥類排遺對水庫水質影響之研究區域擇定在金門太湖水庫及陽明湖水庫，分析結果無法判定水庫水質與鸕鶿數量有正相關性。本計畫完成MSL模場進行試驗，並提出MSL系統施工規範供設計及施工單位參考。

To enhance the reservoir watershed soil conservation and improve its water quality, the Executive Yuan approved “Forward-looking infrastructure development program: The enhancement of reservoir watershed conservation plan”. This plan proposes forward-looking water quality improvement measures for the management of national reservoirs. The purpose of this project include: 1. Formulate the water quality management strategy of national reservoirs, 2. Formulate the water quality management indicators and mechanisms for outlying islands reservoirs, 3. Research and analyze the impact of bird droppings on the water quality of the reservoirs. 4. Support reservoir water pollution reduction technology. 5. Other administrative assistance matters. Pollution survey results in the watershed area of the reservoir show that the main source of total phosphorus pollution in Baoshan Reservoir is the inflow pollution source from Duanchang Bridge to Zhudongzhen in the upstream, while the Nanhua Reservoir is the watershed area orchard and agricultural activities, and the reduction of nitrogen and phosphorus sources should be strengthened. Analyze the historical stratified water quality data of the Environmental Protection Agency and supplement the stratified sampling of reservoirs, put forward recommendations for the improvement of the water quality monitoring plan for the water environment. Reservoir water quality management strategies are based on the water quality status and water supply of the reservoir as determining factors. It is recommended that the Shimen, Liyutan, Zengwen, Wushantou, and Nanhua reservoirs should be prioritized for implementing water quality improvement. Analysis of the suitability of outlying island reservoir water quality indicators and reservoir water quality management regulations, etc., the result is that outlying island reservoir water quality management should focus on drinking water quality and safety. The study area for the impact of bird feces on the water quality of the reservoir was selected as the Taihu Reservoir and Yangming Lake Reservoir in Kinmen, the analysis results could not determine the positive correlation. This project completes the MSL system field test and proposes the MSL system construction specification for the design and construction unit's reference.
