Research On Reachability Of Guangzhou Urban Park In The Context Of Land And Space Planning

Urban park green space planning,as an important component of national spatial planning,is one of the important means to build an ecological civilization and a beautiful China.Urban park green space is an important outdoor activity space for urban residents.With the progress of urbanization,the contradiction between the growing demand for green space by residents and the mismatch between green space resources has become increasingly prominent.The reasonable layout of urban parks is of great significance for promoting social fairness and harmony.At present,there is a lack of detailed discussion on the rationality of the distribution of urban parks.Scholars study the reachability of urban parks and analyze the factors that affect the reachability of parks.The evaluation methods of park reachability mainly include buffer analysis,index statistics,proximity distance,Gravity model and network analysis.The network analysis method is based on the traffic network data,and uses Arc GIS software to analyze the reachability of urban park green space.Compared with other methods,the road resistance can be taken into account,and the analysis results are more objective and accurate.This paper uses Open Street Map to obtain the traffic network data of Guangzhou,introduces residential land data to analyze the matching degree of residential land and parks,determines the park location through the list of parks in Guangzhou,classifies urban parks according to different travel modes of residents,and analyzes the park reachability of different travel modes.Introduce the per capita park area location entropy to analyze the differences between different administrative regions.The results show that although the reachability of motor vehicles in Guangzhou is high,the reachability of walking and riding is general.The reachability of different administrative regions is far from each other,and the space matching between the permanent population and the urban park is generally good.In the process of improving the reachability of urban parks in Guangzhou,it is necessary to consider the high degree of completion of the urban area,so small parks such as community parks or parks should be added in the city center.In the process of establishing comprehensive parks and specialized parks,more entrances and exits should be set up,while matching corresponding public transportation services.In addition,improve the slow traffic network in old urban areas,such as walking and cycling networks,and link various open spaces through slow traffic networks.
