摘　　要：本文以兰州市中心城区城市公园绿地为例,以POI数据为基础数据,合理评价各城市公园绿地服务能力;根据人群活动强度的POI数据分析城市居民对公园绿地需求,并以此为基础优化城市公园绿地布局。结果显示:①兰州市中心城区<2hm^(2)的公园数量不多,2~20hm^(2)公园在城关区分布较为集中,>20hm^(2)公园分布较为均匀;②西固区和七里河区公园绿地分布较少且公园绿地类型单一;③居民对公园绿地的需求最高主要集中在城关区,并向四周逐渐减弱,并提出了城市公园绿地布局的优化建议,以期为未来进一步优化城市规划提供有效支持。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.
