The Route Selection Evaluation And Planning Strategy Of Urban Greenway Under The Background Of Nationwide Fitness

Chronic disease caused by lack of physical activity is one of the major health problems faced by modern people. Public health is one of the important issues in the field of of urban planning and through urban planning and design to solve of the public health problems is current research hotspot. Grasping the opportunities brought by the greenway construction boom under the background of national fitness and reserching route Selection method of urban greenway based on physical activity promotion is the research direction of solving the public health problem by urban planning and design.First of all, studying the domestic and foreign literature and summarizing the influence factors of built environment on physical activity can clear hitting-point which combine greenway with fitness. Secondly, it summarizes the using intensity differences and influence factors of greenway through the domestic and foreign reaserch. The influence factors are classified as three categories:land use, accessibility, and greeneay design features. Dalian Jinzhou greenway is choosed to carry on empirical research. Based on the actual survey data, it analyses influence factors of built environment around greenway which influence the greenway use intensity. The result indicates that the land use diversity and residential proximity can promote the greenway using intensity on whole level and accessibility promote the physical activity amount on individual level. Again, route selection principle of urban greenway based on physical activity promotion is put forward and evaluation system of route selection is builded. The route selection principle includ minimum interference, diversity of land use, near residential, convenient and natural cure. A series of evaluation index about physical activity promotion is brought into urban greenway suitability evaluation system. And the analytic hierarchy process (AHP) is applied to determine index weight. Finally, planning and design strategies of urban greenway are disscussed from three aspects of the layout, space design and planning management on the basis of suitability evaluation to realize the goal of national fitness.
