摘　　要：研究采用植被指数(NDVI)法,运用ArcGIS对苏南运河区域2022年5—9月MOD13遥感影像数据进行处理,测算和分析苏南运河植被覆盖度。同时运用无人机航拍结合Photoshop像素计算分析方法,对部分河段的植被覆盖度进行验证。研究成果可为苏南运河健康评估、幸福河湖建设成效评估、生态修复、岸线开发利用等提供一定的参考,对于其他河道的植被覆盖度测算也具有参考性。In this study,NDVI method and ArcGIS were used to process the MOD13 remote sensing image data of the Sunan Canal region from May to September 2022,and the vegetation coverage of the Sunan Canal was calculated and analyzed.At the same time,UAV aerial photography combined with Photoshop pixel calculation and analysis method was used to verify the vegetation coverage of some river sections.The research results can provide certain references for health assessment,construction effectiveness evaluation of happy rivers and lakes,ecological restoration,shoreline development and utilization of Sunan Canal,and also have reference value for the vegetation coverage calculation in other rivers.
