西南喀斯特地区500m土壤侵蚀模数数据集(2015年)

本数据集包含了西南喀斯特地区500m土壤侵蚀模数数据集(2015年)，空间分辨率为500km，数据类型为栅格数据。DEM数据为SRTM数据，精度己经过验证，在全球得到广泛应用;并结合遥感降水数据，通过降水降尺度研究获取2015年尺度1 km空间分辨率降水结果，按照就近原则并取平均获得1期的降水数据(2015)，并进一步计算降雨侵蚀力;将土地利用/覆被分为6个工级类，25个II级类;在己有数据的基础上，进一步将所有空间数据转换到同一投影坐标Albers等积投影并重采样到90m的空间分辨率再参与空间运算。

This dataset provides the 2015 500 m-resolution soil erosion modulus dataset for the Southwest Karst Region, with an original spatial resolution of 500 km and formatted as raster data. The DEM data used is sourced from SRTM, whose accuracy has been validated and is widely applied globally. Combined with remote sensing precipitation data, 1 km spatial resolution precipitation products for 2015 were obtained through precipitation downscaling studies. One phase of 2015 precipitation data was generated by applying the nearest neighbor principle and averaging, based on which rainfall erosivity was further calculated. Land use and cover are classified into 6 first-level categories and 25 second-level categories. On the basis of existing datasets, all spatial data were uniformly converted to the Albers equal-area projection coordinate system, resampled to a spatial resolution of 90 m, and then utilized for spatial computations.
