The Landscape Design Of Rural Corridors Based On River Restoration

River corridors have both ecological and cultural functions and are important carriers of ecological civilization in beautiful countryside.In the past few decades,due to the prominent contradiction between social development and ecological protection in China,the ecosystem of many rural River corridors has been destroyed.With the rise of the concept of river restoration in foreign countries,At present,domestic research on river corridor restoration and reconstruction has gradually begun to focus on,but the main research object is urban river background,while the case for rural river corridor is relatively small.Facing the increasingly serious ecological problems of rural River corridors,it is urgent to study how to effectively restore the ecology and improve the human settlements environment by using ecological concepts and landscape design methods.The research results also have great significance for the rural river landscape design of ecological restoration in the future.Based on the concept and method of river ecological restoration,this research carried out the investigation and analysis of rural rivers in China,selected Shea River,Qiaoyi Town,Wangcheng District,Changsha City,as the research object,and summarized the ecological restoration landscape design strategies suitable for the corridors of rural rivers in China.The main results are as follows:(1)By analyzing and taking some experiments from domestic and foreign river restoration cases,the common points of successful ecological restoration projects are pointed out,that is,the design follows the natural law and promotes the restoration concept of harmony and unity between man and nature.(2)Based on the summary of relevant concepts,it is pointed out that the principles of ecological design should pay attention to the connectivity of rivers,he function of rainstorm protection and the stability of slopes and banks.Natural materials should be used as far as possible in ecological restoration to consider the comprehensive ecological service function of rivers.(3)This research takes the corridors of rural rivers in China as the object of study and analysis,and finds that the current situation of river corridors is mainly reflected in theserious ecological problems,prominent social contradictions,loss of regional culture,etc.The design of river restoration lacks ecological concept,and the phenomenon of ecological restoration gimmicks appears in the process of practice;compared with urban rivers,the environment of rural rivers tends to be more self-contained.However,ecology is rich in animal and plant ecosystems,and river elasticity space is large.(4)The ecological restoration of water quality should try to avoid the secondary pollution of chemical methods by using techniques such as operating biology,vegetation construction and microbial degradation.River ecological restoration should make rivers close to nature by means of reconstructing rivers and restoring winding characteristics.The ecological restoration of riverbank is carried out by combining the engineering means of natural stone and the natural means of constructing plant communities.(5)Taking Sha River,Qiaoyi Town,Wangcheng District,Changsha City,as an example,this study finds out its ecological problems through field investigation and data statistics,and puts forward a series of comprehensive ecological restoration design methods based on water quality restoration,River reconstruction,habitat creation and planting rest.Finally,combined with the research content of the full text,the ecological restoration landscape design strategy of rural River corridors with low disturbance,sustainability,multi-function and regionalism is put forward.Rural River corridors,as a linear landscape space of humanities,society and ecology,are the core of creating a beautiful ecological environment.It is an important measure to carry out ecological restoration landscape design in rural construction in China.
