Abstract
Taking urban parks and green spaces in the central urban area of Lanzhou as an example,this paper uses POI data as the basic data to reasonably evaluate the service capacity of urban parks and green spaces.According to the POI data of crowd activity intensity,it is shown that residents have different levels of demand for urban park green space in the city,and on this basis,the layout of urban park green space is optimized and adjusted.The results show that:(1)Between 2 to 20 hectares are concentrated in Chengguan District,and parks larger than 20 hectares are more evenly distributed;(2)In Xigu District and Qilihe District,the distribution of park green space is less and the type of park green space is single.(3)Residents'demand for parks and green space is the highest,mainly concentrated in the old city,and gradually weakens to the surrounding areas.Finally,some suggestions for optimizing the layout of urban parks and green spaces are put forward,in order to provide effective support for further optimization of urban planning in the future.关键词
