黄土高原1:100万降水量等值线图（1951-2010年）

数据集为黄土高原降水量数据，包括年平均降水量、最大年降水量、最小年降水量、年平均降水日数、最大年降水日数、最小年降水日数、年降水日数变异系数CV等值线图，各月降水量、各月降水日数等值线图、各季及汛期降水量等值线图、各季及汛期降水日数等值线图、各量级年降水量等值线图、各量级年平均降水日数等值线图，不同量级年降水日数变异系数CV等值线图、年短历史各时段最大降水量等值线图、年长历时各时段最大降水量等值线图共75幅图。数据集来自王万忠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 precipitation data for the Loess Plateau, with a total of 75 maps. These maps cover: contour maps of annual average precipitation, maximum annual precipitation, minimum annual precipitation, annual average precipitation days, maximum annual precipitation days, minimum annual precipitation days, and the coefficient of variation (CV) of annual precipitation days; contour maps of monthly precipitation and monthly precipitation days; contour maps of seasonal and flood-season precipitation and precipitation days; contour maps of annual precipitation of different magnitudes and their corresponding annual average precipitation days; contour maps of the CV of annual precipitation days for different precipitation magnitudes; contour maps of maximum precipitation across various short-term historical periods; and contour maps of maximum precipitation across various long-term historical periods. This dataset 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 et al. and published by Science Press. This data can be used as a reference for relevant research, teaching activities, and managers at all levels in the fields of hydrology, water conservancy, soil and water conservation, ecology, environment, agriculture, land consolidation and other related areas.
