摘　　要：以昆明中心城区2010、2015和2019年遥感影像目视解译后公共绿地信息数据为研究对象,从整体尺度、行政区域和环形单元等方面,用数理统计与空间分析法相结合,对公共绿地空间演变特征进行分析。结果表明:昆明中心城区公共绿地在2010—2019年期间呈现持续增长的趋势,呈贡区公共绿地面积增长速度最快,盘龙区面积增长速度较慢,其他三个单元增长速度保持中速;环形单元中一、二、三环区域公共绿地增长速度较缓慢,四环公共绿地面积增长明显。Taking the public green space vector data of Kunming central urban area after visual interpretation of remote sensing images in 2010,2015 and 2019 as the research object,this paper analyzes the spatial-temporal evolution characteristics of public green space combined mathematical statistics with spatial analysis,from the 3 aspects of overall scale,administrative region and circular unit.The results show that the public green space in the central urban area of Kunming presents a continuous growth trend from 2010 to 2019,it has the fastest growth rate in Chenggong District and a slow growth rate in Panlong District,while the other 3 administrative units have maintained a medium growth rate;the public green space of the 1st,2nd and 3rd Ring Road area have a relatively slow growth rate,while it has an obvious growth rate in the 4th Ring Road area.
