| With the acceleration of urban construction and the increasing level of urbanization,a large number of development and construction have caused the extrusion and destruction of urban secondary rivers.At the same time,the focus of urban governance is more on the main rivers,which leads to the deterioration and even extinction of secondary river environment.At the same time,with the increasing improvement of people’s living standards,the pursuit of quality of life and living environment is also changing with each passing day.People’s inherent hydrophilicity puts forward higher demands for urban water environment.The ecological and landscape environment of urban secondary river waterfront space is declining,which is difficult to meet people’s needs.The relevant departments of the state also realize that flood control water conservancy can not be the only channel Function,need to establish a multi-functional value system.However,in the past practice of urban secondary river management,on the one hand,it is hoped that simple engineering measures can be taken to save manpower and meet the functions of flood discharge,waterlogging elimination,black and odor elimination,on the other hand,the relevant departments often lack overall consideration on ecological restoration,landscape construction and pollution control of urban secondary river waterfront space.Because of its unique mountainous urban terrain,the central urban area of Chongqing has many problems,such as large longitudinal slope of river,deep river valley,large height difference between revetment and river,which virtually increases the difficulty of waterfront space design.The past many renovations have had little effect.So far,there are still some problems,such as fragile ecosystem,serious water pollution,lack of function,lack of regional culture and landscape display.Therefore,how to continue the original landscape style of the waterfront space of the secondary river,restore the clear water and green bank of the river,and become an open leisure green corridor in the city is worthy of our attention.From the perspective of landscape architecture,combined with ecology,ecological water conservancy engineering,water conservancy engineering and landscape aesthetics,this paper studies and discusses the landscape optimization strategy of waterfront space of urban secondary rivers.Following the logic of "finding problems-analyzing problems-solving problems-Case Study",this paper studies the landscape optimization strategy of waterfront space of urban secondary rivers.The first chapter is the introduction,which mainly describes the research background,research purpose and significance of this paper,and combs the research results in related fields at home and abroad,and puts forward the overall research framework of this paper.In order to find out the problems,the second chapter combs the general situation of waterfront space construction of secondary rivers in Chongqing central area,classifies and summarizes the characteristics of secondary rivers in Chongqing central area through field research,and puts forward the problems and difficulties of waterfront space construction of secondary rivers in Chongqing central area based on the previous research.The third chapter is to analyze the problems,mainly through summarizing the value of urban secondary rivers,analyzing the real contradiction of the current situation of waterfront space construction of secondary rivers in the central city of Chongqing,putting forward the construction demands of waterfront space of secondary rivers in the central city of Chongqing.Finally,by selecting excellent waterfront space construction cases at home and abroad,the design points are analyzed and summarized.The fourth chapter is to solve the problem,mainly according to the domestic and foreign excellent case design points and related theories,combined with the specific construction difficulties and demands of secondary river waterfront space in the central city of Chongqing,taking the secondary river waterfront space in the central city of Chongqing as the object,carries on the strategy of waterfront space urban water relationship optimization,landscape optimization,ecological restoration and other demands Response,put forward the corresponding landscape design principles and construction strategies.The fifth chapter is a case study.Taking "landscape design of Liangjiang New District in Chongqing Panxi River Basin" as a case,the paper introduces the general situation of Panxi River comprehensive treatment project,clarifies the project background and design influencing factors,and puts forward multi-level analysis planning and targeted solutions combined with the previous strategies.Verify the feasibility of waterfront space construction demands and landscape optimization strategy in practice.The sixth chapter is the conclusion,which mainly discusses and states the main achievements and shortcomings of the paper.Through the above research methods and optimization strategies,the following research results are obtainedFirst,the paper focuses on the current situation of the waterfront space of secondary rivers in the central urban area of Chongqing,combined with relevant subject knowledge,clarifies the value and demands of secondary rivers in the central urban area,and refines the three starting points of landscape construction of secondary rivers in Mountainous Cities: urban water relationship,landscape optimization and ecological restoration,and puts forward the design strategies with pertinence and universality.Second,the combination of landscape,ecology and water conservancy project is considered and designed.Advanced technology strategy and unified planning consideration are used to demonstrate the feasibility of the combination of water conservancy project,landscape and ecology design,and concrete practice is carried out to make the gray infrastructure ecological and landscape,become an important landscape node and activity space in waterfront space,and make waterfront space more convenient The landscape optimization,water conservancy function and ecological restoration between the two areas have achieved the best effect.The secondary river waterfront space landscape optimization is combined with urban planning,and urban green space and greenway system network are comprehensively considered to improve urban ecological landscape pattern and public open space system,improve urban ecological quality and stimulate urban vitality... |
