Application Of Soil-stone Ecological Engineering In City River Revetment Space

In recent years,due to the development of the city,most of the rivers have been cut straight,the river bank of the land was narrowed by the construction land,so that the river ecological environment has been severely damaged,lack of contact with the city,the lack of ecological green land,people hydrophilic activities difficult The Soil and rock ecological engineering is a combination of ecological restoration technology and landscape planning and design methods,taking into account the principles of water ecosystems and human health needs of the community,to maintain ecological balance,to create a barge space and maintain the habitat environment Very important significance,so the application of urban river channel shore soil ecological practice is the trend.Based on the ecological theory and ecological technology,this paper systematically combs the basic concept of soil mechanics and earthwork in urban river bank,and sets up the research framework of "rock and soil ecological engineering-bank-space".This paper analyzes the research status of related fields in China and abroad by using field research method,case analysis method and literature research method.Summed up the existing soil and rock ecological construction of the unit,its flexible combination with the application of the barge space,and at the same time with the combination of hydrophilic facilities to create a rich and varied barge space form.This paper analyzes the excellent cases of domestic and foreign application of ecological engineering,summarizes the advantages and draws lessons from the relevant experience,and summarizes the basic model of the application of the eco-construction method of the urban river channel.This paper chooses the middle section of Yitong River in Changchun as a simulation case,and applies the method of constructing the land in the article to the bank of Yitong River to prove its practicability.The main results of this study are threefold: The application of the earth rock ecological engineering method in the river bed can be combined with the hydrophilic facilities properly.For example,pool and riffle with hydrophilic plank,weir and planting into the pool,and the combination of step splash Island,which has not only ecological function but also has the function of cultural landscape.Second,in the construction process of embankment can be flexibly combined all kinds of debris ecological engineering application to create a level of rich and has the ecological function of the revetment.Third,to build front space should try to retain their original natural rock substrate,appropriate use of ecological engineering.Make the construction method better integrate with nature,and harmonize with the living environment of the two sides of the strait.
