云南省公里格网植被减少表土损失量数据(2005)

本数据集包含云南省2005年公里格网植被生态系统土壤保持量，空间分辨率为1km，时间分辨率为年。主要用于地理学、生态学、资源环境科学等方面的相关研究。将降水数据经过降水降尺度处理，数据分辨率为1km。基于arcgis工具利用DEM提取坡长、坡度因子，基于三峡库区中部涪陵区的径流小区观测得到的降雨侵蚀力回归模型计算降雨侵蚀力，通过土壤类型提取土壤可蚀性因子等，在arcigis10.2工具箱里，使用栅格计算器计算得到

This dataset contains the 1-kilometer grid soil conservation amount of vegetation ecosystems in Yunnan Province in 2005, with a spatial resolution of 1 km and an annual temporal resolution. It is primarily applicable to relevant research in disciplines such as geography, ecology, and resource and environmental science. Precipitation data was processed via precipitation downscaling to achieve a resolution of 1 km. Slope length and slope factor were extracted from DEM using ArcGIS tools. Rainfall erosivity was calculated using a regression model of rainfall erosivity derived from runoff plot observations in Fuling District, central Three Gorges Reservoir Area. Soil erodibility factor was extracted based on soil types. The final dataset was generated using the Raster Calculator tool in the ArcGIS 10.2 toolbox.
