我国1km2以上2865个湖泊2018-2021年水体面积遥感监测数据集

该数据集为第一次全国水利普查得到的我国1km2以上的2865个湖泊2018-2021年水体面积数据集，数据集来自中国水利水电科学研究院自主研发的湖库水体遥感监测产品生产系统，数据集生产使用的影像以国产高分一、六号WFV 16m影像为主，针对鄱阳湖和洞庭湖两大季节性湖泊，利用Sentinel-1雷达数据进行了补充监测，所有监测结果均经过人工核实。数据集以矢量格式存储，包括约40万条湖泊水体矢量，平均每个湖泊每月有3次有效监测。该数据集包含我国湖泊水体动态变化信息，可为研究湖泊对气候变化和人类活动的响应提供数据支撑。

This dataset is a water body area dataset covering 2,865 lakes with an area of 1 km² or larger in China, obtained from the first national water census and spanning the period from 2018 to 2021. It is derived from the remote sensing monitoring product production system for lake and reservoir water bodies independently developed by the China Institute of Water Resources and Hydropower Research. The imagery used for dataset production mainly adopts domestic GF-1 and GF-6 WFV 16m resolution images; for the two large seasonal lakes, Poyang Lake and Dongting Lake, Sentinel-1 radar data was utilized for supplementary monitoring. All monitoring results have been manually verified. The dataset is stored in vector format, containing approximately 400,000 lake water body vector records, with an average of 3 valid monitoring observations per lake per month. This dataset contains dynamic change information of lake water bodies in China, providing data support for research on the responses of lakes to climate change and human activities.
