江苏省十大湖泊水文要素变化数据集（2003-2019）

该数据集包含2003-2019年江苏省十大湖泊（太湖、洪泽湖、高邮湖、骆马湖、石臼湖、滆湖、阳澄湖、白马湖、邵伯湖和淀山湖）的水位、面积和水量变化，为研究江苏省近年来的湖泊水文生态系统平衡提供了重要的参数。
十大湖泊的水位数据基于Envisat/RA-2、Cryosat-2、ICESat、ICESat-2测高卫星获得；面积数据基于Landsat TM/OLI光学影像采用改进的归一化水体指数提取。对水位数据完整的四个湖泊（洪泽湖、高邮湖、滆湖和太湖），根据水位和面积结果估算了2003-2019年的水量变化。
与实测水位对比，卫星测高获取的所有湖泊的水位都有显著的一致性（α = 0.05），平均绝对误差为0.168 m。
该数据集提供了2003-2019年江苏省十大湖泊的水位、面积和水量变化，可以为江苏省水资源的管理与调度提供数据支持。

This dataset contains water level, area and water storage variations of the top ten lakes in Jiangsu Province (Taihu Lake, Hongze Lake, Gaoyou Lake, Luoma Lake, Shijiu Lake, Gehu Lake, Yangcheng Lake, Baima Lake, Shaobo Lake and Dianshan Lake) from 2003 to 2019, which provides critical parameters for studying the lacustrine hydrological and ecological balance in Jiangsu Province in recent years.

Water level data of the ten lakes were obtained from altimetry satellites including Envisat/RA-2, Cryosat-2, ICESat and ICESat-2; lake area data were extracted from Landsat TM/OLI optical images using the Modified Normalized Difference Water Index (MNDWI). For the four lakes with complete water level datasets (Hongze Lake, Gaoyou Lake, Gehu Lake and Taihu Lake), water storage variations from 2003 to 2019 were estimated based on the derived water level and area results.

Compared with in-situ water level measurements, the water levels of all lakes retrieved via satellite altimetry exhibit significant consistency at the significance level of α = 0.05, with a mean absolute error of 0.168 m.

This dataset provides water level, area and water storage variations of the ten major lakes in Jiangsu Province from 2003 to 2019, and can offer data support for water resource management and scheduling in Jiangsu Province.
