黄河中游多沙粗沙区基础边界数据集

“粗泥沙”主要指黄河上中游水土流失所产生的，通过河道输移到下游并淤积在河道（含三门峡水库）中，在淤积物中占比较重的（主要指主槽中）粗颗粒泥沙。 1996年至2000年，由黄河水利委员会（以下简称黄委）水文局、黄河水利科学研究院、陕西师范大学、中国科学院地理研究所、内蒙古自治区水利科学研究院和黄委绥德水土保持科学试..."Coarse sediment" mainly refers to coarse-grained sediment generated by soil and water loss in the upper and middle reaches of the Yellow River, which is transported to the downstream reaches via river channels and deposited in the river channels (including the Sanmenxia Reservoir), accounting for a relatively large proportion of the deposited sediment, especially in the main channels. From 1996 to 2000, this dataset was jointly developed by the Hydrological Bureau of the Yellow River Conservancy Commission (hereinafter referred to as YRCC), Yellow River Institute of Hydraulic Research, Shaanxi Normal University, Institute of Geography of the Chinese Academy of Sciences, Water Resources Research Institute of Inner Mongolia Autonomous Region, and YRCC Suide Soil and Water Conservation Scientific Experiment (the text is truncated as provided).

背景概述

该数据集整合了黄河中游多沙粗沙区和粗泥沙集中来源区的边界矢量数据，基于1996-2000年和2004年的研究项目成果，利用DEM、遥感影像和实地调查解译生成，旨在为黄河水土流失治理和泥沙控制提供技术支持。数据集属于地球科学领域，关键词涉及支流界、黄河流域等，可通过甘肃省生态科学数据中心平台完全共享获取。
