黄河上中游淤地坝高分辨率光学遥感卫星影像样本数据集

淤地坝是修建在多泥沙沟道中用于固沟减蚀、蓄洪滞洪和控制泥沙输移的一种水土保持工程措施，具有良好的水土保持功效，在拦泥淤地、滞洪蓄水、建设农田、巩固退耕还林（草）、发展生产、减轻黄河泥沙、改善生态环境等方面均发挥了重要作用。基于Google Earth 19级遥感影像数据，在黄河中上游...

Silt-trapping check dams are soil and water conservation engineering measures constructed in sediment-laden gullies, which serve to stabilize gullies and mitigate erosion, detain and store floodwater, and control sediment transport. They exhibit excellent soil and water conservation efficacy, and play critical roles in trapping sediment and accumulating farmland, flood detention and water storage, farmland development, consolidating the Grain for Green Project (converting cropland to forest and grassland), boosting production, reducing sediment load of the Yellow River, and improving the ecological environment. Based on Google Earth Level 19 remote sensing image data, in the middle and upper reaches of the Yellow River...
