Study on the Spatial Layout and Influencing Factors of Park and Square in Changsha City based on Big Data
Urban park and square plays a crucial role in economic and social development,urban vitality,and quality of human life.This paper uses python to crawl the POI data of Gaode map and applies spatial analysis and other methods to analyze the characteristics of the spatial distribution pattern of park and square and the influencing factors in Changsha,so as to provide reference for the urban spatial planning and high-quality development of the city.The research results show that:(l)Changsha park and square has obvious clustering characteristics in spatial distribution,showing the distribution pattern of main and secondary centers,decreasing from the center to the edge;(2)The main center of the park and square mainly contains Wuyi square,Tianxin park,etc.and its surrounding areas,the sub-center is distributed in the northern part of Yuelu district and the southern part of Kaifu district,and the park and square of other regions form a small-scale agglomeration phenomenon in the local space;(3)The density of park and square is closely related to the city's natural geography and location factors,and shows a positive correlation with the level of economic development and road network density;(4)Urban park and square should be combined with multi-dimensional elements such as nature,economy,humanities and traffic,and the coupling of park and square functions,forms and other functional spaces should be taken into consideration to achieve scientific planning and organic and balanced layout.
