Research On The Impact Of Urban Space Morphology Based On The Health Of The Respiratory System

After several decades of rapid urbanization in China,the urban spatial form has also changed rapidly,followed by air pollution and the prevalence of specific diseases of urban and rural residents.These have become research central issue for built environment and public health.With the advent of a comprehensive well-off society,Healthy urban construction has also become one of the goals.However,as the building density increases,the floor area ratio continues to increase,the greening land is reduced,the air flow inside the city is slowed down,and the pollutants are difficult to settle and spread in time.The physical health of urban residents is greatly threatened.Especially in recent years,the concentration of nitrogen oxides,sulfides and suspended particulates in the air has been increasing,and the haze weather has been frequent,and the respiratory environment of urban and rural residents has been seriously threatened.At the same time,since the 1990 s,respiratory diseases have been one of the main causes of death in urban and rural residents in China,and the mortality rate of respiratory diseases has been on the rise for the next 20 years.Urban spatial morphology research based on respiratory health can help urban planners better grasp urban construction and provide a good breathing environment for urban and rural residents.This study directly constructed the framework of the relationship between respiratory health and urban spatial morphology,and extracted 158 districts and counties that represent the overall level of respiratory health in China as a sample,and used the combined mortality of lung,organ and bronchus as indicators of respiratory health.The construction land ratio,forest land integration degree,land compactness,population density,and road network density are used as indicators of urban internal space form,and three multiple linear regression models are constructed to measure the influence and degree of urban spatial form factors on respiratory health.Identify the geographical climate,GDP,Per-Urban land(the total plaque of construction land as the proportion of total administrative land use),SHAPE_AM four main influencing factors,and explain the mode of action of these elements.The research is divided into five parts.The first chapter gives a detailed explanation of the research background,research purposes and content.The second chapter gives a general overview of the current research literature in this area,and points out the promotion point of this research.The third part analyzes the current situation of respiratory health in China from the geographical space,compares the differences in mortality of respiratory diseases in the sample and explores the causes;the fourth part is the important content of this study,constructing a multiple linear regression model between respiratory health and urban spatial morphology,based on the regression results Explain the explanation;Chapter 5 summarizes the research results and points out the inadequacies,providing directions and suggestions for further research.
