A Study On The Landscaping Of Riverside Flood Control Facilities In Mountainous Cities

Riverside flood control facilities are the key content of large river basin flood control construction,large mountainous rivers have special topographic conditions and hydrological conditions,and riverside flood control facilities have the special potential to combining with landscape.However,because of the inconsistent planning and disorderly development patterns occur in the development and construction of river bank lines with the continuous renewal of cities,necessary communication and innovative connections are lacked between riverside flood control facilities and surrounding urban environment,urban water conservancy and flood control projects under a single target lead to problems like lack of hydrophilic recreation space,uneven landscaping quality of flood control facilities and etc,which bring adverse effects on giving full play to the role of flood control facilities in integrated services include transportation,relaxation,business,ecological environment.Therefore,it is necessary to explore the landscape strategy of coastal flood control facilities which is different from plain city and mountain city.Based on the investigation and analysis of the landscape status of the flood control facilities along the main urban areas in Chongqing,this paper discusses the landscape pattern and the existing problems of flood control facilities along the Yangtze River in the mountainous cities,and puts forward the landscape strategy for the future mountainous areas The city along the river flood control facilities to provide reference and recommendations.The main research results are as follows:(1)This paper analyzes the influencing factors and general principles of the multi-functional carrying capacity of the city along the Yangtze River flood control facilities and the basic attributes of the activity space,and points out the particularity of the landscape facilities of the mountainous cities along the plains:(1)Vertical height difference,narrow horizontal width of the flood control and revetment space structure;(2)The highest flood level is lower than the average surface of the city floor;(3)Destruction of Space Continuity of Flood Control and Revetment of Riverside Elevated Road and Production Coastline.(2)This paper investigates and analyzes the flood protection and revetment of more than 20 kilometers of the two banks of the two main rivers in Chongqing.Summed up as:(1)Production,lifestyle,ecological three kinds of functional use of nature;(2)Straight-line,slope-type,step-down,stepped and compound five types of structural form;(3)Linear trails,overlooking the space,construction sites,square space,bridgehead five forms of recreational space;(4)Internal reachable and external reachable two aspects of hydrophilic reachable form;(5)Soft,hard and soft and hard combination of three kinds of facade landscape form;(6)Encirclement warning facilities,pavement,sculpture sketch and other details of the design form.(3)Based on the field investigations and analysis,the paper combines them with the current landscaping patterns of riverside flood control facilities in the main urban area of Chongqing as well as some practical problems,and puts forward the following six principles suitable for the landscaping of riverside flood control facilities in mountainous cities,including rationalization of function utilization nature,compounding of structure morphologies,diversification of recreation space,three-dimensional design of accessible transportation both from inside and outside,heterogenization of facade design and regionalization of detail design,and besides,the paper also discusses about some specific strategies for the landscaping of riverside flood control facilities in mountainous cities according to different landscaping principles:(1)Structural form,should be from the macro reasonable planning and control of flood control standards,microscopic use of double revetment structure to achieve multi-level flood control standards to adapt to the structural design;(2)Hydrophilic accessibility,should be from the internal rich three-dimensional base surface convergence Path,external construction of three-dimensional walk,the car traffic system to improve the spatial availability of flood control facilities and the use of efficiency;(3)Recreational space should strengthen the macro-control and organization,while strengthening the diversification of the node space to create at the same time,pay attention to the linear hydrophilic trail rhythm sense to build;(4)Facade design,soft facade should improve the landscape quality of vegetation slope protection;(5)Detailed design,should be injected into the regional culture,to strengthen the humanized design of the enclosure,and should focus on lighting design,optimize the night effect,and improve the flood warning signs,the design should be designed to enhance the visual design,system.
