臺北水源特定區乃是大臺北地區最重要之水源地，其水源水質水量之安全與潔淨將直接影響大臺北地區約500萬人口之用水品質。臺北水源特定區包含翡翠水庫集水區，其集水區內種植茶園的面積約為500公頃，茶園之施肥若尚未被農作物吸收，會隨暴雨挾帶進入河川，並對翡翠水庫造成水質污染的影響。 水源局為持續推動非點源污染削減，改採污染源源頭分散式處理之方法，擬利用茶園既有排水路及其匯流處，設置淨化設施進行在槽處理，爰需辦理金瓜寮溪流域茶園集水面積及排水路現況調查與LID現地處理規劃，並於金瓜寮溪流域擇1處茶園示範區進行規劃及設置，作為後續推廣LID設置之基礎。 本計畫主要的工作包括(1)蒐集國內外LID實務應用案例及其對水質改善應用之相關研究，(2)建立金瓜寮溪流域茶園分佈環境背景資料，(3)完成茶園現況調查及LID場址規劃，(4)辦理農藥使用及合理化施肥用藥教育宣導、LID現地處理說明會，(5)製作LID說帖與茶園非點源污染削減BMP及LID宣導摺頁，以及(6)LID示範區設置與操作維護作業規範編製。預期執行後達到(1)完成金瓜寮溪之茶園環境背景資料及現況調查，並將LID各類型模組單元化，提出LID場址規劃，以供後續水質改善參考依據，(2)整體污染削減規劃，逐步降低金瓜寮溪之茶園非點源污染，以確保翡翠水庫之水質潔淨，(3)完成LID設施之示範設置，以有效推行茶園的非點源污染管理措施等目標。 依據工作項目與內容，本計畫除蒐集國內外LID實務應用案例及其對水質改善應用之相關研究外，並利用空照圖等建立金瓜寮溪流域茶園分佈之環境背景資料，同時針對茶園面積1公頃以上之土地20處，進行茶園集水面積及排水路現況調查，並完成29處LID場址規劃（含茶園位置圖、LID配置規劃圖、排水流向等），建立20處茶園所有權人清冊，完成地籍套繪圖、地籍圖謄本、土地登記簿謄本等資料之整理。 本計畫配合水源局完成500份LID說帖、1,000份茶園非點源污染削減BMP及LID宣導摺頁之編製，並辦理兩場次農藥使用及合理化施肥用藥教育宣導，與兩場次LID現地處理說明會，兩場說明會後已有六位茶農已簽署茶園設置植生滯留槽設施同意書，表示願意提供茶園土地配合設置LID設施。 本計畫以坪林區農會黃水樹理事的茶園做為示範場址，完成示範區二處（a、b兩處）植生滯留槽設施之設置作業，每處植生滯留槽佔地1平方公尺，利用茶園既有的排水路，設置於排水匯流處，可處理0.5公頃茶園的初期暴雨逕流。由LID示範區場址前後水質檢測結果可知，經植生滯留槽處理後，平均總磷去除率約為73%，懸懸浮固體去除率約為91%，氨氮去除率約為31%。 植生滯留槽LID設施後續推動規劃如下：(1)以化整為零方式推動，規劃於茶園排水路末端設置LID設施，茶園地表逕流經處理後再排入河川，(2)由點到面，分區分年逐步推動，有配合意願的茶農優先設置，規劃每0.5公頃茶園設置一座植生滯留槽LID設施，設置面積以1平方公尺為原則，(3) LID設施採單元模組化設計，以方便後續之管理維護，設置後的LID設施由茶農配合維護，並由政府核發環境友善茶園標章，彰顯茶農對污染防治作業的積極參與。

Abstract Taipei Water District, but the region's most important water source, its safety and quality and quantity of clean water will directly affect the quality of water in Taipei area population of about 5,000,000. Taipei Water contains emerald water catchment area of its tea plantation catchment area of about 500 hectares, of tea if fertilization has not been absorbed by crops, with the storm will be entrained into the river, and water pollution caused by the emerald reservoir affected. Taipei Water District continue to promote the reduction of non-point source pollution, shift to pollution source distributed processing methods, the intended use of the tea garden and the confluence of the existing road drainage, purification facility set up in the slot handle, Yuan must apply tea set Jingualiao River basin Road, water and drainage area of the status of the investigation and handling of LID planning now and in the river basin Jingualiao choose a tea demonstration area planning and setting the basis for a subsequent promotion of LID settings. Water Management Office to continue to promote the reduction of non-point source pollution, shift to pollution source distributed processing method, the intended use of the existing drainage channels and tea confluence, purification facility set up in the slot handle, Yuan must apply tea set Jingualiao River basin Road, water and drainage area of the status of the investigation and handling of LID planning now and in the river basin Jingualiao choose a tea demonstration area planning and setting the basis for a subsequent promotion of LID settings Based on work items and content, LID practices at home and abroad to collect water quality improvement and application case studies applied outside and using aerial photographs and other background information on the establishment of environmental Jingualiao Creek watershed distribution of tea, but for more than one hectare of plantation area land 20, carried out the status of tea catchment area and drainage road survey and completed 36 LID site planning, establishment of 20 tea plantation owner inventory, complete the cadastral sets of drawings, finishing cadastral maps of the land registration transcript and other information. LID, said the completion of 500 posts, 1,000 non-point source pollution reduction tea BMP and LID preparation of promotional brochure and go two times to rationalize the use of pesticides and fertilizer medication education advocacy, and now two times LID handle briefings, two after the description of the existing ten farmers have signed tea set vegetation retention tank facilities consent expressed willingness to provide land for setting LID tea facilities. Farmers in Pinglin District Director of tea tree yellow water as a demonstration site to complete two demonstration area set up operations at the vegetation retention tank facilities, each of the vegetation covering a retention tank meters, the use of tea existing drainage way, set at the confluence of drainage can handle 0.5 hectares of tea early storm runoff. LID demonstration area by the front and rear site water testing results, vegetation retention tank after treatment, the average removal rate of approximately 73% of total phosphorus, suspended solids removal rate of about 91％ on average, about 31% of the average removal rate of ammonia nitrogen. Vegetation retention groove LID facilities subsequent to promote planning as follows: (1) to promote decentralized manner, planning road ends at tea set LID drainage facilities, tea runoff treated and then discharged into the river, (2) point to the surface, partition of years to gradually push farmers there with the intention of setting priorities, planning a tea set per 0.5 hectares of vegetation retention tank LID facilities, set up an area with a m principle, (3) LID facility mining unit modular design to facilitate follow-up of maintenance management, set up by the farmers after LID facilities with maintenance, environmentally friendly tea issued by the Government mark, highlighting the active participation of farmers pollution prevention operations.
