Study On The Disaster Prevention And Risk Avoidance Function Of Urban Greenland In Beijing

The rapid development of the city has improved the living standard and quality of the whole society.However,when we live in a comfortable environment,earthquakes of varying degrees occur every day across the globe,frequent and unpredictable.As the carrier of human life and production,the damage caused by earthquakes is more and more serious.The demand for urban security has also gradually been taken seriously.As an important part of urban construction,green space plays an increasingly important role in urban safety.More and more studies have shown that green space not only has the functions of landscape ornamental,leisure and entertainment and so on,but its own unique characteristics also play an important role in disaster prevention and risk avoidance in the city.Beijing's urban construction has always been at the forefront of the whole country.The construction and importance of urban safety is very high.In 2017,the Beijing city's latest general regulations made it clear that we should build a first-class international harmonious and livable capital,improve public green space and urban safety facilities,and improve the livable level and service ability.Among them,specific requirements have been given to different aspects of the construction of the urban security system and efforts have been made to provide a comfortable and safe environment for urban residents.Whether the final goal of urban planning can be achieved is largely uncertain,which is interfered by many factors.Therefore,the research on the status of the city is particularly important,which can provide strong support for the recent construction.This paper first summarizes and summarizes the research progress at home and abroad,which is convenient for reference and research.Afterwards,the relevant documents and standards in China are summarized and compared.Through the investigation of the existing green space emergency shelters in the downtown area of Beijing,and combining the theories related to the urban green space system and the urban emergency system,the rationality and the perfection of the function and the structure of the space layout of the urban green space in Beijing city are analyzed and tested.Finally,combined with the analysis of the full text and the results give reasonable suggestions.Due to the limited research ability,we can only discuss the shallow layer of the disaster prevention and avoidance function of green space,and only hope to play a role in attracting valuable advice.
