Research On The Spatial Pattern And Evolution Mechanism Of Beijing Large Park Based On ArcGIS Platform

As the important part of urban landscaping.large park are of great importance to improve the urban ecological environment,urban economic development and to meet people’s daily leisure use.In the ecological aspect,the large park can be an independent ecosystem and can also be associated with the surrounding green space system to form the urban ecosystem,which is of great significance for improving the urban ecological environment.In social aspects,Large parks can be used as city business cards to drive peripheral development and improve the city’s comprehensive influence.It can play an important role in promoting Beijing culture and meeting the daily needs of surrounding residents.In the economic aspect,large park has great significance for urban spatial layout and land planning.In summary,the large parks has great significance for the development and construction of Beijing cities.Explore how to make the spatial pattern of large parks more reasonable;How to make it more responsive to the development of the city;How to make it better meet people’s daily use needs;How to maximize the ecological significance of large parks.These studies on the spatial pattern of large parks are necessary.This paper establishes a large park vector database in Beijing based on the statistical analysis and on-site investigation of large-scale parks larger than 20 hectares within the scope of Beijing Municipality which recorded by Beijing Garden Bureau.Based on the basic vector database of large parks in Beijing using the ArcGIS Platform to quantify and analyze the spatial structure and evolution pattern of Beijing’s large parks.Summed up the characteristics of the spatial pattern of large parks in Beijing.Based on the above,summarized the evolution mechanism of the spatial structure of large-scale parks in Beijing.Finally compare typical large parks in foreign large cities,summarized and analyzed the main problems in the development of large-scale parks in Beijing and proposed the suggestions for how to improvement.hoping to provide strong reference and guidance for the planning and layout of the future large-scale parks in Beijing and even throughout the China.
