摘要

以三峡库区185m观景平台上游消落带生态治理试点为例，阐述了库区消落带两个重要高程段(夏季防洪水位145～152m和冬季蓄水位170～177m)内岸坡遭涌浪侵蚀破坏的现状，并对涌浪的成因及其对消落带岸坡的侵蚀机理进行了分析．研究表明，涌浪是造成库区消落带土壤侵蚀的主导因素；传统硬性加固措施应与生态河岸带构建技术有机结合．根据消落带坡度差异，分别提出了几种可行的生态修复措施，初步构建了一套针对库区消落带两个重要高程段内边坡的生态修复模式．

Abstract

Ecological management was investigated and demonstrated on the 185 m observation platform with-in the water-level-fluctuating zone of the upstream Three Gorge Reservoir. This study addressed the current adverse situation： the side slopes between the two critical elevations(145-152 m

170-177 m) has experi-enced destructive surge erosion. The cause of surges and their erosion mechanism were analyzed. It was found that surges were the main force causing soil erosion. Traditional slope reinforcement measures and eco-logical techniques like riparian zone construction should be combined organically. Several feasible ecological restoration measures were proposed in respect to slopes of various gradients. In addition

an ecological resto-ration modes for the slopes between the two important elevations in the fluctuating zone was developed pre-liminarily.
