| Since the reform and opening up,with the development of China's economy and the improvement of living standards,"healthy China" has become a national strategy,and the quality of the people has gradually improved,providing a guarantee for achieving national prosperity and strength.However,the incidence of chronic diseases that seriously endanger human health,such as hypertension and diabetes,is on the rise,and health problems are becoming more and more serious.The relationship between the health of residents and the built environment is inseparable."Endemic disease" is a typical example of the built environment affecting health.The increasingly prominent respiratory health problems in modern society are also closely related to the built environment.As an old industrial area,Xigu District has concentrated many industrial enterprises in Lanzhou City.The number of patients with respiratory diseases in this area has been increasing year by year.Studying the impact of the built environment of this area on respiratory diseases has positive significance for residents' health.With urban planning and comprehensive research in various disciplines,residents have higher requirements for the improvement of their own quality of life and the quality of the surrounding environment.Therefore,the construction of a healthy city has also become a future urban development model.This article uses data statistical analysis methods and geospatial system analysis methods,based on 7 streets in Xigu District,Lanzhou City,from 2013 to 2018,to conduct relevant research on inpatient data from a hospital respiratory department.The application of this type of data is in this research field.It is a new tentative study.First,analyze the basic characteristics of the sample;then,based on the urban built-up environmental factors surrounding the home address of inpatients with respiratory diseases,select the urban built-up environmental indicators in relevant studies to summarize and discuss the built-up environmental factors and their characteristics that significantly affect respiratory health and use Pearson correlation analysis to quantify the previous research views;finally,with the goal of promoting respiratory health as a goal,put forward specific optimization strategies for land use,spatial form,road network and landscape greening in urban planning and design practice With measures.To provide support for promoting healthy city development and optimizing humansettlements,it has certain theoretical and practical significance in the fields of urban planning and environmental engineering.The following conclusions are drawn through research:(1)From the perspective of time distribution characteristics,from 2013 to 2018,the number of inpatients with respiratory diseases showed a linear growth trend.The number of inpatients in winter and spring was more than that in summer and autumn,and the proportions in the four seasons were 26%,23%,and 24,respectively.%,27%.(2)From the perspective of spatial characteristics,from 2013 to 2018,inpatients with respiratory system diseases were mainly distributed in 3 streets,including Fuli Road Street,Xianfeng Road Street and Xigucheng Street,which were the three with the highest prevalence of respiratory system diseases.Streets have significant spatial distribution characteristics: with the passage of time,inpatients are distributed in a scattered manner,and the distribution position gradually moves northward.The number of inpatients in the adjacent areas of Chenping Street and Xianfeng Road Street increases year by year.(3)Among the built environment indicators,POI mix degree,building density,road line density,road network density,and bus station density have a significant positive effect on the respiratory system prevalence.Road grade,public green space rate,green area per capita and prevalence of respiratory diseases haZve a significant negative impact;There is no significant relationship between POI density and respiratory system prevalence. |
