黄河流域地表水分布的精准制图对于水资源管理、生态环境保护以及防洪减灾等方面具有重要意义。目前,黄河流域仍缺乏精准的长时间序列的地表水分布数据集。为了解决这一问题,本研究基于Google Earth Engine(GEE)云计算平台,融合多源陆地卫星(Landsat-5/7/8/9)遥感影像,构建了黄河流域地表水提取算法,生产了 1986-2023 年黄河流域地表水分布数据集,包括地表水频率数据(WBF)和地表水类别数据(SWC)。通过对水体提取结果的精度进行评估,总体精度OA达到了 97。60%,Kappa系数为 0。95。同时在黄河流域将SWC数据和全球地表水数据集GSW进行了对比,SWC数据的表现在部分地区明显优于GSW数据。本研究生产的数据集可以帮助政府和公众应对黄河流域日益增长的用水需求和水安全挑战。
A dataset of annual surface water distribution in the Yellow River Basin(1986-2023)
Accurate mapping of surface water distribution in the Yellow River Basin is of great significance for effective water resource management,ecological environment protection,and flood prevention.However,there is a lack of precise long-term dataset of surface water distribution currently in the Yellow River Basin.To address this issue,using the Google Earth Engine(GEE)cloud computing platform,we integrated multi-source Landsat satellite(Landsat-5/7/8/9)remote sensing imagery to develop a surface water extraction algorithm for the Yellow River Basin in this study.Based on this algorithm,we further produced a dataset of annual surface water distribution in the Yellow River Basin from 1986 to 2023,including Surface Water Frequency(WBF)data and Surface Water Category(SWC)data.The accuracy assessment of the water extraction results showed an overall accuracy(OA)of 97.60%and a Kappa coefficient of 0.95.Additionally,when compared with the Global Surface Water dataset(GSW)in the Yellow River Basin,the SWC data demonstrated superior performance in certain areas.The dataset produced in this study can assist the government and the public in addressing the growing water demand and water security challenges in the Yellow River Basin.
