Spatial Clustering Characteristics,Influencing Factors And Environmental Coping Strategies Of COVID-19 Patients

At the symposium of scientists,General Secretary Xi Jinping emphasized that it is hoped that the majority of scientists and scientific and technological workers will shoulder historical responsibilities,adhere to the frontiers of science and technology in the world,face the main battlefield of the economy,face the major needs of the country,face the people’s lives and health,and continue to march into the breadth and depth of science and technology.Infectious diseases have always been a major threat to people’s health and a major killer,and have a serious bearing on the development and security of human history and civilization as well as the world economy and society.Since December 2019,the novel coronavirus pneumonia epidemic has not only caused a serious public health crisis worldwide,but also made people pay more and more attention to the construction of a public health security system.The three-year epidemic has had a huge impact on the global social,economic and political landscape.Chapter 1 mainly analyzes China’s novel coronavirus pneumonia,the epidemic situation of the global novel coronavirus pneumonia and the epidemic situation and research status of the novel coronavirus pneumonia in China.Communities have a large number of resident data,including case data and population data.Through data collation,literature review,field survey,induction and deduction,and data analysis,objective analysis can be made on the regional spread of COVID-19.Chapter 2 mainly analyzes the relevant research of infectious diseases at the community level,and studies the relevant theories at home and abroad.China has done some research and exploration on the reconstruction of old residential areas under the background of epidemic,and developed a series of community control methods.Foreign research on the COVID-19 epidemic in the field of landscape architecture has achieved preliminary results,and some cases have been made in Europe,the United States,Japan,South Korea,Singapore and other countries.However,both at home and abroad,there is no relevant literature to analyze the characteristics of the community at the street level in view of the COVID-19 epidemic.Chapter 3 mainly analyzes the spatial distribution and influencing factors of COVID-19 patients in Street D.Taking D Street,Y District,Shanghai as an example,this paper analyzes the data of COVID-19 infected persons(hereinafter referred to as "positive cases")from March to November 2022,using Arc GIS and SPSS analysis methods,combined with environmental factors related to COVID-19 and actual data.The results showed that:(1)The positive cases were mainly concentrated in the old residential areas with high population density and aging degree,which were positively correlated with the area of the district,the number of households,the number of residential buildings,the number of doorways and the number of garbage wing,and negatively correlated with the floor area ratio,construction year,the number of elevators and the greening rate.(2)The regional infection rate was significantly positively correlated with the aging rate,and significantly negatively correlated with the greening rate,volume ratio and other factors;There was no significant effect on vaccination rates.Chapter 4 analyzes the key infected areas of D street.Field visits to the two residential areas were conducted to find out the actual causes of the high infection rate.At the same time,the old community management and environmental coping strategies are explored,from the aspects of basis,demand,put forward coping strategies.Chapter 5 from the perspective of post-epidemic situation,a set of environmental response measures has been sorted out in the aspects of environmental response,greening rate improvement,plant allocation for healing,epidemic prevention and control measures,etc.The role of landscape architecture in the prevention and control of infectious diseases has been strengthened,so as to block the transmission chain of related infectious diseases like the novel coronavirus at the source,and improve the quality of community living through environmental transformation measures.Enhance the "immunity" of communities,and then build a healthy community pattern of "prevention first and prevention combined",so as to provide reference and reference for the real realization of "human community with a shared future" from the perspective of residential areas.
