Study On The Planning And Design Of Revetment Landscape From The Ecological Perspective

As a part of the ecological environment,water bodies are increasingly valued for their ecological functions and landscape effects.This thesis takes the revetment as the research object,uses the methods of literature research,case analysis,field research,induction and deduction,and uses the means of actual case analysis to study the revetment landscape planning from the ecological perspective.According to the combination of different terrain slopes and revetment types,the "lotus joint" model is obtained,and the landscape planning strategies of each component of the model are discussed,providing reference and reference for the same type of landscape planning.The specific conclusions are as follows:(1)Taking the Thames River revetment landscape design in the UK,the Mixi Lake revetment landscape design in Wanzhou,Chongqing,and the ecological revetment landscape design in Shijian Lake as actual cases,according to the steepness of the terrain slope,there are three types of slopes: S1 gentle slope(slope<15 °),S2 middle slope:(15 ° ≥ slope<30 °),and S3 steep slope:(30 ° ≤ slope);According to the materials and forms of the revetment,it can be divided into 12 types of revetments: R1 gabion plant revetment,R2 pond wetland chain,R3 plant cutting revetment,R4 cascade flood plain,R5 strong permeability flood control zone,R6 water storage lake,R7 plant buffer zone,R8 gravel plant revetment,R9 natural gentle slope revetment,R10 ecological floating island,R11 widened river channel,and R12 pebble riverbed.(2)By orthogonal fusion of slope type S and revetment type R,the planning model of the revetment landscape is obtained as the "lotus root" model: lotus root silk is a theme idea based on cultural and ecological backgrounds;According to different site conditions,Ouduan is divided into three strategic spaces: SR1 gentle slope type revetment strategic space,SR2 medium slope type revetment strategic space,and SR3 steep slope type revetment strategic space.(3)According to the "lotus root knot" model,the strategy of determining lotus root silk is to extract local natural landscape,folk customs,meteorological landscape,resident environment and ecological environment elements,and determine the cultural theme through brainstorming;The strategy of the lotus section is to determine the SR1,SR2,and SR3 strategy spaces based on slope and site conditions.SR1 gentle slope revetment strategy space:in terms of ecological strategy,permeable flood control zone,water storage lake and other revetment types can be selected,and in terms of landscape strategy,large-scale streamline plant planting can be adopted;SR2 medium slope type revetment strategy space: In terms of ecological strategy,revetment types such as stone cage plant revetment and plant buffer zone can be selected,and in terms of landscape strategy,plants can be combined with terrain for hierarchical and seasonal matching;SR3 steep slope revetment strategy space: In terms of ecological strategy,ecological floating islands,pebble riverbed and other revetment types can be selected.In terms of landscape strategy,different characteristics of plants can be segmented and combined with terrain.(4)Taking the landscape planning of Yuting ecological revetment as an actual case,the theme is to reproduce the green and beautiful natural ecological landscape of Yuting.It is divided into four areas: A,B,C,and D.The theme is positioned as "Green fir trees greeting the waves","Reeds swaying in the wind","green mountains outside the window",and "Lush and thriving".Among them,SR1 strategy is adopted in Area A and C,SR2 strategy is adopted in Area D,and SR3 strategy is adopted in Area B to practice the "lotus root knot" model and strategy of the thesis.
