中国250米分辨率降雨侵蚀力图（1986-2015年）

该数据集为1986-2015年30年平均年降雨侵蚀侵蚀力因子R栅格值。利用全国范围内2881个水文站（1898个）、气象站（983个）1986-2015年30年逐日侵蚀性降雨量计算得到。运用降雨侵蚀力日模型计算多年平均年降雨侵蚀力的基础上，利用ArcGIS软件利用克里金插值方法进行空间内插，得到全国范围内多年平均年降雨侵蚀力。对图像进行处理分析，进行编辑、处理，图像输出等。

This dataset contains the raster values of the average annual rainfall erosivity factor R over the 30-year period from 1986 to 2015. It was calculated using the daily erosive rainfall data collected from 2,881 hydrological and meteorological stations across the country during 1986-2015, including 1,898 hydrological stations and 983 meteorological stations. Based on the multi-year average annual rainfall erosivity computed with the daily rainfall erosivity model, spatial interpolation was conducted via the Kriging method using ArcGIS software to obtain the nationwide multi-year average annual rainfall erosivity. Subsequent image processing, analysis, editing, and output operations were performed as well.
