Reservoir inventory for China in 2016 and 2021

Two maps containing medium and large reservoirs of China are presented and named (1) MLRC_2016, (2) MLRC_2021 based mainly on Landsat 8 images and other ancillary data sources. They give a national medium and large reservoir extent of 23314.00 and 24888.95 km² respectively. By distinguishing the reservoirs based on uniform data sources and methodology, the proposed dataset is believed to be useful for promoting the research of basic disciplines such as hydrology and environmental science, and assisting watershed-scale environmental planning/monitoring and the national macro-decision-making in terms of integrated management of surface water resources.本数据集发布两幅中国大中型水库分布图，分别命名为MLRC_2016、MLRC_2021，其构建主要基于Landsat 8影像及其他辅助数据源。两幅分布图对应的全国大中型水库总面积分别为23314.00平方千米与24888.95平方千米。本数据集采用统一的数据源与处理方法开展水库识别工作，有望推动水文学、环境科学等基础学科的相关研究，并可为流域尺度的环境规划与监测、地表水资源综合管理相关的国家宏观决策提供辅助支撑。
