Evaluation And Design Of The Use Of The Urban River Ecology Embankments

Urban river revetment is the city’s water ecosystems and terrestrial ecosystems,matter, energy and information exchange is an important place to the transition zone,the urban river embankments provide a variety of aquatic organisms to survive andthrive ideal space, at the same time enhance the biological diversity have importantsignificance, stable river banks, regulation of climate and landscape. Today, however,the city embankments too much emphasis on flood control function, various types ofrigid bulkhead filled with cities in the size of the river, resulting in the complete lossof embankments the function of this important ecological and landscape corridor asecotones. Ecological revetment is not only the formation of the coordination of theriver landscape with the surrounding environment, but also through the establishmentof a rich ecosystem, to achieve the water crystal clear, fish swim, aquatic plants lushnatural landscapes. Therefore, to carry out research of the urban river ecologyembankments of great significance for the protection of the ecosystem of the UrbanWaterfront.In this paper, the study of urban river embankments, analysis of the revetmentecological revetment types and characteristics, to carry out urban river ecologicalrevetment design of the main results are as follows:(1) To analyze a series of concepts and theories of design and ecologicalrevetment, by understanding the research profile of the domestic and internationalurban river ecology embankments, provide guidance for the study of the ecological revetment.(2) To carry out the classification of urban ecological revetment and analysis onthe characteristics of various types of research, field survey showed that: urbanecological water body section can be divided into vertical embankments, inclinedbulkhead, stepped revetment; ecological revetment material can be divided intonaturalprototype revetment, natural type of revetment, artificial and natural embankments;artificial confounding factors can be divided into non-structural ecological revetment,structured ecological revetment.(3) A comprehensive evaluation of urban ecological revetment, through theanalytic hierarchy process to establish a comprehensive evaluation index system ofecological revetment. Comprehensive evaluation of the vertical revetment, inclinedbulkhead and ladder-type revetment three types of example and draw ladderecological revetment is the best option.(4) Through Jiangdong District of Ningbo Urban River as an example foranalysis and research, from the four aspects of design: water and building spacing3M,water and building spacing5M, water and building span5—10M and10M abovewater and building space, and the combination of Urban River four areas: building,commercial building residential construction, cultural construction, ecologicalrevetment design.(5) Urban river ecology embankments plant cultivation can be configured forecological revetment circumstances, a reasonable selection of plants.
