本局於93~94年度辦理「淡水河系河川情勢調查計畫」，調查期間適逢『基隆河整體治理計畫(前期計畫)』執行相關治理工程，因此該計畫針對基隆河河段分別於上中下游辦理生態調查工作，並作為施工參考依據；衡酌『基隆河整體治理計畫(前期計畫)』已完工4年餘，因此有必要針對治理完成後之現況再進行調查，並分析治理前後狀況檢討治理工程對現地環境之影響及改善成效，並針對治理後對生態影響較大河段，提出補強策略建議。

The management and development of the rivers more focused on the water conservancy facilities in Taiwan early period. In recent years, using traditional materials, such as reinforced concrete, to build the hydraulic structure has been declining due to the awareness of river ecology and environmental conservation is gradually being established. To mitigate the flood damage of lower part of Jilong River basin, Central Government executed a flood mitigation project named “Jilong River Overall Improvement Project (Earlier Project)” which cost 31.6 billion NT dollars. The cost was budgeted according to the “Special Act Governing the Management of Jilong River Basin.” This project was executed from July 2002 to May 2005. This project has been completed so far for five years, five typhoons, Krosa, Kalmaegi, Sinlaku, Jangmi, Parma, Megi typhoon, attack during this time. The purpose of this study is to understand whether the administration project had reached anticipated targets. In order to compare the different on river ecosystem and its environment at before, under, and after Jilong River overall improvement project, the investigations and estimation of current status were carried out in this study. According to the conclusions of the investigation and estimation, the design guidelines are proposed for the good performance of the river improvement project. However, the improvement strategies are proposed for the river sections that not achieve the target yet.

本報告評估基隆河整體治理計畫（前期計畫，2002-2005年）完成逾六年後的成效。早期河川治理偏重治水，較少考量生態環境。此為期兩年的調查（2011-2012年）旨在檢討治理工程對現地環境的影響及改善成效。 研究內容涵蓋治理前後的環境變化分析、河道沖淤狀況、河岸護坡抗沖蝕能力、水污染監測削減、植生適性與生態效益，以及魚類生態指標等。最終目標是針對未達預期目標的河段提出補強策略與建議，以建立流域整體治理方針，降低水土災害風險並提升生態環境改善成效，為後續河段治理提供參考準則。
