Study On The Selection Of Urban Greenway Under The Background Of National Fitness

With the continuous evolution of urbanization and the continuous change of technology,the health problems of Chinese residents,especially the public health problems in urban areas,are becoming more and more complicated.The prevalence of chronic diseases is not only caused by environmental pollution,but also largely due to the convenience of technology that causes residents to lack physical activity in their daily lives.Under the background of the national fitness,how to promote the implementation of national fitness program through planning and design provides a direction for consideration in the field of urban planning to address public health issues.Based on this,this thesis discusses the needs of users and strives to create a healthy living environment for residents in order to achieve the purpose of promoting the occurrence of national fitness behavior.First of all,this thesis discusses the relationship among environment-behavior-psychology.Combined with relevant theoretical research,the direction of this paper is clarified,and it is expected to promote the occurrence of national fitness behavior by shaping the urban greenway to meet the needs of national fitness.Secondly,field investigation and questionnaire survey were conducted on the central urban area of Baoshan City to analyze the behavioral characteristics of national fitness.Combined with the hierarchy of needs theory,this thesis analyzes the demand for national fitness in detail,and summarize the features that the urban greenway based on national fitness behavior should have.Then,this thesis summarizes the evaluation system of urban greenway route selection constructed by scholars from different perspectives and extracts commonly used evaluation indexes.On this basis,the evaluation index with leisure fitness as the goal is added,and the demand for national fitness is integrated into it as the index layer.The weight of each index is determined by analytic hierarchy process,and the evaluation system of urban greenway route selection under the background of national fitness is constructed.Finally,based on the research theory and combined with practical cases,this thesis elaborated on the current situation,problems and planning in the research area,and the traditional construction method is used to analyze and superimpose the elements of greenway layout,and the overall layout of the greenway in the central urban area of Baoshan City is preliminarily formed.The constructed evaluation system is used as the theoretical basis for scoring evaluation,and the corresponding improvement strategies are put forward according to the scoring results,which provides a theoretical basis for the construction of greenway in Baoshan City in the later period.
