Analysis on Current Situation and Development Trend of Ecological Revetment Works in Middle and Lower Reaches of Yangtze River

Abstract

In this article, analysis has been made with regard to current situation of ecological revetment works and revetment requirements of river channels in the middle and lower reaches of Yangtze River, types of ecological revetment and etc. The development trend of ecological revetment and its application prospect are also discussed. The analysis indicates that, after the impoundment of Three Gorge Reservoir, the erosion of the river channels in the middle and lower reaches of Yangtze River will result in severe situation like local river channel adjustment and local bank collapse and continuous weakening of river ecological system. It is necessary to keep on strengthening the comprehensive control of the river reaches adopting in the future.
