黄土高原1：100万典型小流域边界及水系图（2018年）

该数据集是黄土高原典型小流域边界及水系，包括岔巴沟、韭园沟、南小河沟等13个典型小流域边界及水系矢量图及13个小流域的基本概况，数据来源于王万忠、焦菊英等编著由科学出版社出版的《黄土高原降雨侵蚀产沙与水土保持减沙》。此数据可供水文、水利、水土保持、生态、环境、农业、国土整治等有关研究、教学、和各级管理人员参考此数据可供水文、水利、水土保持、生态、环境、农业、国土整治等有关研究、教学、和各级管理人员参考。This dataset contains the boundaries and water systems of typical small watersheds on the Loess Plateau. It includes vector maps of the boundaries and water systems of 13 typical small watersheds including Chabagou, Jiuyuangou, Nanxiaohegou and others, as well as the basic profiles of these 13 small watersheds. The data is sourced from the monograph *Rainfall Erosion, Sediment Yield and Sediment Reduction via Soil and Water Conservation on the Loess Plateau*, compiled by Wang Wanzhong, Jiao Juying and other scholars, and published by Science Press. This dataset can be used as a reference for relevant researchers, educators and managers at all levels working in the fields of hydrology, water conservancy, soil and water conservation, ecology, environmental protection, agriculture, land consolidation and other related disciplines.
