現行河川管理事業已邁向兼具治水、利水、親水之整體性河川環境管理，以維護河川環境生態資源永續，河川環境管理要考量河川生態環境之保育，首要條件即是了解河川生態系統對河川環境之適應能力。「和平溪河川情勢調查」即是因應前述需求，以和平溪河系為單元，辦理生物性環境、非生物環境及水利工程環境之整合性調查與分析。本計畫工作目標係在以河川環境整體角度對和平溪河系有關之基礎資料，包括人文、社經及水文資料、生物環境、河川空間利用等辦理河川情勢調查，以及建立生態資料庫、網頁查詢系統，作為推展河系河川事業、河川管理及提供水利工程人員適合和平溪之近自然工法規劃、設計所需資訊。

River development and management in Taiwan before over-emphasized water treatment engineering, but less considered the whole environmental ecology. In recent years, since environmental protection consciousness has been more and more important, there is a need to do more investigation to make up the shortage of existing material which should be integrated for the reference of public. To promote river business, river management, environmental conservation and rehabilitation, and provide the reference of natural treatment design for hydraulic engineering institute, all the basic material including Humanities, physiographic, hydrological data, biological, space utilization need to be collected in this project. The project is to investigate Heping River situations. The work target is to compile GIS ecosystem data as unit of river for the whole Heping Rivershed and to build it into the database at the website for the Management Information System of River’s Investigation.

本調查報告針對和平溪下游河段進行環境生態及河川情勢調查，範圍涵蓋和平溪主流及楓溪。調查發現和平溪水質呈中度污染，主要受懸浮固體偏高影響，主流水量充沛但楓溪枯水期流量減少。棲地方面，大部分河段品質佳，但楓溪部分河段因人為工程受損嚴重。水域生物種類數因水流湍急、含砂量高而貧乏，陸域生物則種類豐富，包含多種保育類動物。報告建議加強礦場及砂石車運輸管理，並將和平溪劃分為人工經營段與河川保育段，以期達到河川永續管理與生態保育之目標。
