Research On Ecological Restoration And Landscape Construction Design Of Urban Inland River

Since the 20th century,human productivity has made great progress.The industrial development has brought great material wealth,but at the same time,the urban inland river ecological environment has also been destroyed.The restoration of urban inland rivers in foreign countries started earlier than that in China,and now it is becoming mature in technology.However,the domestic urban development started later,and some areas are still in the mode of "natural resources for economic development".Therefore,the current urban inland river ecological environment in China needs to be protected and restored.The guiding ideology of "vigorously promoting the construction of ecological civilization and reversing the trend of ecological environment deterioration" was put forward in the 18th National Congress of the Communist Party of China,which provides an opportunity for the ecological transformation of urban inland rivers.With the further development of the city,the single function sewage river in the city is gradually transformed into a landscape river with ecological benefits.The practice case of "urban double repair" provides a reliable basis for the ecological restoration and landscape construction of the urban river.This paper studies and understands the methods and theories of urban river restoration at home and abroad through literature research,selects the appropriate strategies and methods of urban river reconstruction,records the ecological status of Huishan open channel by field survey,understands the real needs of the surrounding citizens by questionnaire survey,uses induction and deduction method to combine the ecological status of Huishan open channel,and transports Based on the theory and technology of water conservancy and municipal administration,the open channel of Huishan in Shenyang is analyzed and studied.In this paper,ecological restoration and landscape construction are combined to study.First of all,the related concepts and technologies of the study are summarized,and the concepts of urban river,urban double repair and lost space activation are limited,and the possibility of urban river ecological restoration and landscape construction is discussed in combination with low impact development theory,riverbank ecological reconstruction theory and lost space activation theory,and the key restoration technologies such as sludge treatment technology and barge are discussed This paper introduces and compares the technologies of bank reconstruction and aquatic plant purification.Secondly,combining with several cases of urban river reconstruction and space renewal,it analyzes the design ideas and proposed strategies and methods,and then puts forward the design principles and optimization strategies for the ecological restoration and landscape construction of urban rivers in cold regions.Thirdly,it introduces the ecological status of Huishan open channel and the needs of surrounding citizens To investigate and understand the causes of ecological deterioration of Huishan open channel,and to analyze the real needs of urban residents through the sorting out of the questionnaire survey;finally,to Shenyang Huishan open channel as the reconstruction object,the water,soil and plant landscape were re planned and re arranged,the urban space was optimized and designed,and the transformation results of Huishan open channel were advanced by using the space syntax Line verification shows that the optimized space is improved in accessibility,convenience and symbiosis.Finally,this paper puts forward specific ecological restoration measures and space renewal strategies for the reconstruction of the cold urban inland rivers,which has certain reference significance for the surrounding cold cities.However,due to the completion of the project schedule,this paper fails to make a comprehensive analysis of the space renewal results on site,and there are some shortcomings.
