Research On The Measurement And Optimization Of Rural Community Life Circle From The Perspective Of Residents Behavior Activities

China ’s modernization and urbanization have entered the stage of urban-rural integration.The speed of urbanization has slowed down,and the trend of rural population transferring to cities has been declining.At the same time,the development of rural areas in China is growing,the construction of various facilities is gradually improving,and the rural human settlements is also improving.However,from the current situation of rural communities,the construction of top-down public service facilities often ignores the actual needs of villagers in rural areas.The research and practice of rural community life circle with rural residents ’ behavior activities as the research object has gradually entered the field of urban and rural planning.This thesis takes the rural areas in the Gucheng district of Lijiang as the research object.After summarizing the relevant research and practical planning of various rural community life circles at home and abroad,it will research the behavior activities of rural residents.By researching the internal relationship between the characteristics of rural residents ’ behavioral activities and travel behaviors,combined with the three-level public service facility configuration system of ’ city-town-village ’ in the Gucheng district,from the aspects of behavior type and time cost,the rural community life circle in the Gucheng district is measured as four circles : self-sufficient life circle,daily life circle,basic life circle and expanded life circle.The OD distance cost matrix is used to establish a full-domain travel time cost model,and the measurement of the rural community life circle in the Gucheng district is quantitatively researched based on the time cost model.According to the results of the measurement research,it is found that there are some problems in the rural community life circle of the Gucheng district,such as the uneven coverage of a single service center,the large difference in the development of inter-regional traffic network,and the mismatch of the service population scale of the life circle center.In the optimization stage,the corresponding elements are comprehensively supplemented and improved,and from the perspective of rural community life circle,this thesis puts forward some suggestions on the village layout,the scale of public service facilities and the urban and rural transportation system in the Gucheng district,in order to provide reference for making up for the " crack " between "top-down" and "bottom-up".
