中文摘要：

城市公园绿地与居民的日常生活密切相关,目前对公园绿地的服务分析主要用的是基于行政单元的人口统计数据,难以反映行政单元内的指标差异.本研究利用精确到门牌号的上海市实有人口数据,基于GIS的栅格分析方法对上海市外环以内的公园绿地服务现状进行分析.按不同等级公园的服务半径对研究区域进行划分,分析了每个公园绿地的服务范围、服务人口、单位面积的服务人口和人均公园绿地面积;计算整个研究区域内公园绿地的服务盲区,分析了服务盲区的面积、人口数量和人口密度.

英文摘要：

Urban public green space is fundamentally important for residents＇ daily life.Traditional methods for calculating service population of urban public green space often adopt administrative regions as analytical units for statistical analysis.This relies on the division of administrative units and cannot reflect population variation within a unit.This paper performed the analysis at a finer resolution with more accurate real population data within the outer ring of Shanghai.The methods and procedures were proposed to calculate the results based on raster analysis of Geographic Information System（GIS）.First,with cost allocation function in GIS,service area,service population and service population per unit area were analyzed by assigning different service distances of each urban public green space.Second,no service area,population and population density in no service area were analyzed.
