摘　　要：为准确掌握江苏省水域面积动态变化情况,贯彻落实《江苏省水域保护办法》。该文采用0.5 m空间分辨率高景卫星影像,开展2021—2022年江苏省水域面积变化监测与分析工作。监测结果表明,2022年水域面积呈增加态势,其中淮安、连云港、泰州、徐州、常州、宿迁和无锡7市水域增加,苏州、南通、镇江、南京、盐城和扬州6市水域减少;2021—2022年水域面积增加的类型为湖泊、河流;水域减少的类型为坑塘、沟渠、水库;重点河湖水域面积有明显增长,主要由于洪泽湖、白马湖、骆马湖等实施退圩还湖,湖泊水域增加。本次监测成果,为各级水行政主管部门进行水域保护和管理提供重要的数据支持和决策依据。In order to accurately understand the dynamic changes of water area in Jiangsu Province and implement the"Measures for the Protection of Water Waters of Jiangsu Province".This paper uses 0.5-meter spatial resolution high-view satellite images to carry out monitoring and analysis of water area changes in Jiangsu Province from 2021 to 2022.Monitoring results show that the water area will increase in 2022,with the water areas of Huai'an,Lianyungang,Taizhou,Xuzhou,Changzhou,Suqian and Wuxi increasing,and the water areas of Suzhou,Nantong,Zhenjiang,Nanjing,Yancheng and Yangzhou decreasing;2021-2022 The types of water area increase are lakes and rivers;the types of water area decrease are pits,ponds,ditches and reservoirs;The water area of key rivers and lakes has increased significantly,mainly due to the return of Hongze Lake,Baima Lake,Luoma Lake,etc.to lakes to lakes,and the lake waters have increased.The results of this monitoring provide water administrative departments at all levels for water protection and management.Provide important data support and decision-making basis.
