摘要

本研究利用MUSIC（the Model for Urban Stormwater Improvement Conceptualisation）將永安集水區劃分為三種土地利用型態，分別為林地、農地及住宅區，以及三種結構性BMPs（Best Management Practices）設施，分別為草溝、草帶及滯留池。依據永安集水區之水文資料及水質採樣分析項目：懸浮固體物（Suspended Solids, SS）、總磷（Total Phosphorous, TP）及氨氮（Ammonia Nitrogen, NH3-N）分析之結果，顯示暴雨水質濃度大多高於晴天水質濃度，且SS、TP及NH3-N之濃度易高於甲類水體水質標準，故於永安集水區下游處設置結構性BMPs設施為翡翠水庫管理局明確之決策。以MUSIC模擬三種方案之結構性BMPs組合後得知，方案一（草溝=>上方草帶=>下方草帶=>滯留池）、方案二（滯留池=>上方草帶=>下方草帶=>草溝）及方案三（上方草帶=>下方草帶=>草溝=>滯留池）處理後之水質濃度，皆小於甲類水體水質標準，其中，以方案一之去除效果最佳。翡翠水庫集水區為重要之水源水質保護區，做好非點源污染削減設施具有示範、宣導及技術推廣功能。本BMPs示範區驗證結構性BMPs設施對非點源污染有相當之去除功效，若加以利用MUSIC評估結構性BMPs設置優先順序，進而從小型結構性BMPs示範區推廣到水庫集水區全面性的實施，必能達到水質改善的目標。

This research utilizes MUSIC（the Model for Urban Stormwater Improvement Conceptualisation）in Yong-Ann watershed to divide into three kinds of land utilizing type attitudes, it is the forest land, farmland and residential area respectively, and three kinds of structural BMPs（Best Management Practices） facilities, it is the grassed swales, vegetated buffer strips and detention basins respectively. According to the hydrological data and the water quality samples and analyses item of Yong-Ann watershed: Suspended Solids（SS）, Total Phosphorous（TP）and Ammonia Nitrogen（NH3-N）result of analysing, show that the concentration of water quality of rainstorm is mostly higher than the concentration of water quality of the sunny day, and the concentration of SS , TP and NH3-N is apt to be higher than the class-A water body water quality standard, so set up structural BMPs facilities for the clear decision of Feitsui Reservoir Administration in the downstream place of Yong-Ann watershed. Learn after making up with structural BMPs of three kinds of schemes of MUSIC simulation, scheme one（grassed swales=> upper vegetated buffer strips=> lower vegetated buffer strips=> detention basins）, scheme two（detention basins=> upper vegetated buffer strips=> lower vegetated buffer strips=> grassed swales）and scheme three（upper vegetated buffer strips=> lower vegetated buffer strips=> grassed swales=> detention basins）treated concentration of water quality, all smaller than the class-A water body water quality standard, among them, the best with getting rid of the result of scheme one. It is the important water quality protection zone of source of water in the Feitsui Reservoir watershed, Do a good job of nonpoint source pollution cuts down facilities can have demonstrate, propaganda and technology popularization function. This BMPs demonstration area proves that structural BMPs facilities have suitable getting rid of the efficiency to nonpoint source pollution, if utilize MUSIC to assess structural BMPs and set up priority, and then popularize from small-scale structural BMPs demonstration area to the comprehensive implementation of the reservoir watershed, can reach the improved goal of water quality.
