Research On Method Of Green Way Selection Of Taiping Town In Harbin

Rapid urbanization leads to the sprawl of cities and the fragmentation of green space.With the destruction of spatial continuity,the ecological service function of the urban and rural green space system has been continuously weakened,and a series of problems have emerged,such as aggravated environmental pollution,soil and water loss,and reduced biological diversity,ecological civilization construction is facing severe challenges.As an important part of the green space system,greenway can provide comprehensive ecosystem services,It is one of the important ways of ecological civilization construction.As an important "connecting point" of urban and rural greenway,It can promote the integration of fragmented greenway patches,ensure the integrity and continuity of urban and rural greenway network,improving the overall ecological service function of greenway and realizing the network construction of urban and rural integrated greenway system.Therefore,it's very important and necessary to deeply study greenway in small towns.This paper first discusses the problem of selecting green line of small towns in combination with linear green infrastructure from the perspective of ecosystem services,and analyzes relevant theoretical and practical results at home and abroad,and finds the inadequacies of related research in China.The core part of the thesis proposes to evaluate the value of ecosystem services in linear urban green infrastructure in small towns,and to select suitable greenway construction objects,which can increase the ecological elements of greenway selection and ecosystem services using linear green infrastructure.Function to enhance the overall ecosystem service function of small town greenways.The paper uses multi-criteria decision-making to establish an evaluation system for green town green line selection,and evaluates the land suitability of small town greenways from three aspects: traffic convenience,landscape resource richness and land carrying capacity,and then quantifies the value of ecosystem services.The method and network analysis method verify the rationality of the greenway line selection scheme,thus constructing a green line selection route,laying a foundation for scientific planning of small town greenways.Finally,this thesis takes Harbin Taiping town as an example,making ecosystem service value coefficient of local adjustment in a linear green infrastructure on the basis of ecosystem services value evaluation and the suitability of roads,analyzing the selected route adjustment based on ArcGIS,for getting the greenway network diagram of Taiping town,and by the ecosystem services value quantification method and network analysis method,verifing the rationality of the greenway selection based on the ecosystem services value quantification.
