摘　　要：本文以城市公园绿地为研究对象,基于多源多时序卫星遥感影像,研究了城市公园绿地的提取方法,针对城市公园绿地包含地类复杂多样的特点,提出了一种基于GIS辅助的公园绿地提取方法。分别从公园绿地面积变化、人均公园绿地面积变化和空间分布变化等多个角度,分析了长沙市内五区建成区范围内城市公园绿地在2015~2022年间的变化情况,建立了基于卫星遥感影像的城市公园绿地动态监测体系。This article takes urban park green space as the research object and studies the extraction method of urban park green space based on multi-source and multi temporal satellite remote sensing images.In response to the complex and diverse characteristics of urban park green space,a GIS assisted park green space extraction method is proposed.From multiple perspectives such as changes in park green space area,per capita park green space area,and spatial distribution,the changes in urban park green space within the five built-up areas of Changsha City from 2015 to 2022 were analyzed.Finally,a dynamic monitoring system for urban park green space based on satellite remote sensing images was established.
