Research On Ecological River Revetment Materials

Ecological river includes natural ecological river and after artificial construction or restore that the river meet ecological criteria. This article described on the premise that it ensure safety and stability of the river, focus on ecological and environmental requirements. Through the ecological restoration that the river internal system and the surrounding environment in a spontaneous balance, coordination state of the river system.Revetment engineering as an important part of the river system, it is crucial in the construction of ecological river construction and maintain to the ecological function. Therefore, the revetment material has requested ecological function of ecological river construction. It can maintain ecological functions of the river or improve overall habitat conditions. Specifically refers to the river bank slope after excavation, using artificial planting vegetation or ecological engineering measures, for the effective slope protection and reinforcement through interaction between vegetation and soil on bank; reached the requirements of safety and stability of the slope surface, restore the damaged of natural ecological environment, is a kind of ideal ecological slope way. River bank slope with ecological revetment materials can not only control soil erosion effectively and also can improve river water quality, and the river ecosystem has repair effect. The improvement of the ecological function can raise the overall effect of landscaped and to beautify the environment.In this paper, based on the Yangtze River along the river slope characteristics, the development process and the characteristics of biodiversity,on the appropriate river ecological revetment material analysis, experiment, comparison, by comparing the pros and cons of various ecological revetment material characteristics, analyzed the ecological revetment, the action of the river water quality and ecosystem restoration, research the ecological river revetment material, to provide a theoretical reference for the river protection project implementation of ecological revetment materials.The main research of this article are as follows: first, discussion on the problems faced by the development of the river, on the basis of the existing data to elaborates the ecological management process and progress at home and abroad to collected and sort out the data of the existing ecological revetment material; Secondly; to sum up of the health river’s evaluation method and criteria, introduced the ecological revetment way and material types. And then in the test section of the river take on ecological river slope and material security and stability, ecological health, and regional coordination habitat analysis; for each test program arranged and carried out the advantages and disadvantages of each test program effectiveness analysis. Finally, compared with other types of ecological revetment material, the results show that geogrid stone cushion material has a better comprehensive evaluation index, the overall structure and function of ecological system are more perfect, draw it as a test of the suitable ecological revetment material type. Expounds the ecological river revetment material to improve the applicability of the river channel slope and ecological effect, the development of ecological revetment material for future, and discuss some problems needed to be further solved.
