摘　　要：黄河中游粗泥沙集中来源区是对黄河下游河道主槽危害最大的地区,通过界定具体范围,有针对性地加强区域水土流失治理,是减少下游河道泥沙淤积的关键所在。本数据集是在黄河中游多沙粗沙区、粗泥沙集中来源区界定研究成果基础上,采用人工目视解译方法提取黄河中游多沙粗沙区、多沙粗泥沙集中来源区边界矢量数据。本数据集包括黄河中游多沙粗沙区区界和粗泥沙集中来源区边界矢量数据,基本反映了黄河中游多沙粗沙区、粗泥沙集中来源区的具体位置,可作为黄河中游水土流失治理的基础数据支撑。The coarse sediment source area in the middle reaches of Yellow River is most harmful to the main channel of the lower reaches of the Yellow River.Defining the specific scope and strengthening the regional soil erosion control are the key to mitigating sedimentation of the lower reaches of the river.This dataset is produced by using visual interpretation from remote sensing images based on the research results of boundary delimitation of the high and coarse sediment yield area and centralized source area of coarse sediment in the middle reaches of the Yellow River.This dataset basically reflects the specific locations of the two areas,and can be used as the basic data for the water and soil loss control in the middle reaches of Yellow River.
