摘要

傳統邊坡穩定工程－混凝土構造物，其表面平滑，生物很難附著存活，對環境保育衝擊甚大，故以自然生態工法創造優質環境，遂為當前重要課題。邊坡自然生態工法須因地制宜，依山坡地土砂災害發生類型及環境特性，採行最適當之對應治理機制。自然生態工法規劃設計採行之五化原則：表面孔隙化、高壩低矮化、坡度緩坡化、材質自然化、界面透水化，能達到防災安全、生態保育、休閒遊憩三合一功能目標，以提高治理之附加價值與經濟效益。本文亦探討土石流及崩塌地源頭處理、河溪治理及特殊地質（紅土台地及泥岩）邊坡穩定採自然生態工法之做法及原則。

Conventional slope engineering is made up in form of concrete structures in which the quite smooth surface will result in the difficult living condition for other live form. To avoid the impact of traditional concrete slope engineering on the environmental care, the ecological engineering method presents promising meaning.To achieve the multiple goals of the ecological conservation, safety precaution and recreation center, five fundamental principles, such as small openings of surface, lowing the higher dam, decreasing the angle of slope, adopting natural material and permeable interface, shall be taken into account in planning and design to raise the additional value and economic benefits. Also, this paper describes the ecological engineering method in the treatments of debris flow, the source of slumps and the slope stability in lateritic terrace and mud stone.
