Study On The Spatial Distribution Of Leisure Agriculture In Shanghai City

As an effective way to promote the integration of three industries,stimulate the innovate of agriculture,the development of rural areas and the rich of farmers,leisure agriculture is developing rapidly in recent years.Under the influence of huge market demand and limited development space,the structural characteristics of spatial distribution in urban suburban leisure agriculture are increasingly apparent,and become a hot spot of research.This paper take the spatial distribution of leisure agriculture in Shanghai as research object,study on it's distance distribution and spatial agglomeration characteristics quantitatively;And Introducing the theory of Geography and Economics,from the distance characteristics of attractions and activities into the circle type development model of leisure agriculture in city,from the phenomenon of attractions agglomeration to the characteristics of agglomeration districts,lay theoretical basis for the relevant planning.On the one hand,In study on distance distribution,the methods of city center distance and radius of gyration are used to study the traffic distance and time consumption between leisure agriculture attractions and urban center in Shanghai,and proposed that the density distribution of attractions is generally asymmetric inverted U-shaped curve distribution with the increase of distance.The distance-benefit model is constructed from the perspective of the net income of tourists,and the distribution characteristics of the attractions and several special positions are explained.This paper classifies the main types of leisure agriculture activities,and summarizes the different characteristics of their changes with distance,then explain the reason.On the other hand,in the study on spatial distribution,based on the statistics of Shanghai leisure agriculture attractions,this paper uses the kernel density analysis method to construct the density contour line,and quantifies the agglomeration degree of leisure agriculture attractions in Shanghai,then divides them into five aggregation levels according to the density.According to the difference of scale and density of each agglomeration districts,refining different types of agglomeration districts.The formation dynamics,internal industrial structure,organizational patterns and other characteristics are studied.Finally,the leisure agriculture agglomeration districts of Shanghai is divided into three types:mixed type,park type and hub type.From the view of industry growth trend,this paper believe the hub type agglomeration district should be the main direction of future development.Finally,analysis the factors affecting spatial distribution of leisure agriculture,the leisure agriculture resources in Shanghai were divided into three categories: natural resources,industrial resources and cultural resources.Evaluate each resource separately and sum up as a complete evaluation of leisure agriculture resources in Shanghai.Combined with the development demand of Shanghai,delineate the key cultivation districts,optimization and promotion districts,restricted development districts.Based on the characteristics of attractions and activities,the overall planning of urban land use,put forward the network oriented leisure agriculture structure mode,and the different types of agglomeration districts in Shanghai.Based on the characteristics of spatial distribution of leisure agriculture in Shanghai,this paper proposed the distance-benefit model of leisure agriculture and the classification method of agglomeration districts,provide a new analysis framework for leisure agricultural space research,the conclusion can provide basis and guidance for the optimization of spatial distribution of leisure agriculture in Shanghai and other metropolis.In addition,leisure agriculture as an important part of urban leisure andrecreation system,the relevant research also has a certain significance to perfect the distribution of urban public open space.
