Discussion On Landscape Planning Of Village Type River Lake Ecological Buffer Zone

As a new ecological restoration protected mode,the river lake ecological buffer zone has the functions of buffering and intercepting pollution,purifying water quality,etc.At present,the research on it in China mainly focuses on the single planning of ecological restoration,and the research on landscape is relatively rare.This paper takes the village type river lake ecological buffer zone as the research object,and uses literature research,interdisciplinary research,case study and other methods to explore the landscape planning strategy of village type river lake ecological buffer zone from the perspective of ecological restoration,providing reference and reference for the planning of the same type of projects.Through literature review and summary,the relevant research theory of Village-type river-lake ecological buffer zone is summarized,and the scope of this thesis is defined.Taking the lakeside ecological buffer zone of Erhai Ring Valley in Dali City and Shengjiawan River ecological buffer zone in eastern Jiashan City in Zhejiang Province as practical cases,it is analyzed and concluded that:(1)Considering the relationship between production and life of villagers and buffer zone,the Village-type river-lake ecological buffer zone can be divided into three types: village community space type(about 20-35 m wide),village transition space type(about 35-120 m wide)and village ecological protection type(over 120 m wide).Define the research object of this thesis as the transition space type of villages.(2)According to the two structures of buffer zone water level range and land buffer zone,the landscape strategy model of 1+5+1 is constructed by combining the composition of garden space,i.e.one ecological restoration strategy and five large space structures: water environment space,slope protection space,constructed wetland space,land vegetation space and path passage space and one human landscape strategy.(3)The strategies of ecological restoration are interference removal,basement restoration,habitat improvement and plant restoration.(4)Five large space strategies are as follows:Water environment landscape strategy: reasonable planning of the spatial layout of water body,construction of different water body shapes,selection of landscape facilities and sketches according to local conditions,appropriate plant allocation to enrich water environment space.Slope protection landscape strategy: according to engineering measures,select slope protection form,use different landscape materials for ecological slope protection,use soft and hard plant materials,and combine landscape art techniques to create slope protection landscape.Landscape strategy of constructed wetland: sort out water system,design appropriate hydrological conditions,extend coastline,enrich coastal environment,select appropriate vegetation and landscape layout,and increase interaction space between human and wetland.Landscape strategy of land vegetation area: Select plant species with strong local adaptability in different regions,combine vertical and horizontal directions to design plant landscape space structure,and pay attention to the seasonal design of plant color.Landscape strategy of path passage: According to the current situation of site,design the road,establish the green vegetation landscape belt along the line,create road landscape node and set up animal ecological passage as far as possible.(5)Humanistic landscape strategy: on the basis of protecting the existing cultural heritage,make use of the local culture to guide the overall planning plan,excavate the symbols of human landscape elements and apply landscape facilities sketches,emphasize the integration with rural production and living culture,and select new technical means to highlight the human landscape atmosphere.Practice the 1+5+1 landscape strategy model theory with the project of lakeside ecological buffer zone of Qishuhu Village in Huangshan City.The theme is "Construct green ecological barrier and seek for exotic villa Taoyuan life",and the space structure is "one zone,three zones",one zone: human landscape link;Three districts: residential area,living area and production area.Each District formulates corresponding ecological restoration strategy and landscape strategy.After completion,the project ecological index and landscape effect are tracked and evaluated for one and a half years,which provides strong evidence for the construction of Village-type river-lake ecological buffer zone,as well as ideas for the interdisciplinary integration of landscape architecture and environmental engineering.
