Research On The Spatial And Evolution Mechanism Of Beijing City Park Based On GIS

Urban park green space has the most comprehensive service function in urban green infrastructure,and is the core component of urban green space system.The development of urban park green space is of great significance to promote urban construction.At the same time,due to its unique social status,historical background and cultural environment,Beijing has a high research value in the development and evolution of park green space.To sum up,it has a strong practical application value for the study of Beijing park pattern and how to make a scientific and reasonable layout.This paper takes the urban park green space of the main urban area of Beijing as the research object,through the analysis,statistics and on-the-spot investigation of the park information recorded by Beijing Municipal Bureau of landscape and greening,establishes the Beijing Urban Park vector database,and studies the spatial pattern,development and evolution characteristics and evolution mechanism of Beijing urban park at the present stage based on GIS,FRAGSTATS and other software.The overall research is divided into four stages: the first stage is theoretical research,which combs the concept of park green space,the spatial pattern of green space and related theories at home and abroad;the second stage is to study the background information of Beijing,clarify the research scope,summarize the development history of park green space and the current situation of park construction;the third stage is to study the spatial pattern evolution characteristics of urban park green space Research,including the changes of the spatial pattern of the park in each period,as well as the research of the spatial distribution characteristics in each period;the fourth stage is based on the previous research results,to analyze and study the evolution mechanism of the spatial pattern of urban park green space,and to summarize and analyze the problems in the development and construction of Beijing Park Green Space Bureau,and put forward targeted opinions and suggestions.
