一带一路沿线20国坡度坡长因子数据集

一带一路沿线20国坡度坡长因子（LS）数据集，基于公开的1弧秒分辨率SRTM数字高程数据（Shuttle Radar Topography Mission, SRTM；http://srtm.csi.cgiar.org），经过去接边、去除伪条纹等和滤波除噪等预处理，利用CSLE模型中的坡度坡长因子算法和本项目研发的坡度坡长因子计算工具（LS_Tool），计算得到7.5弧秒分辨率坡度坡长因子图。一带一路沿线20国坡度坡长因子数据，是基于CSLE进行土壤侵蚀速率计算的必备数据，同时分析泛一带一路沿线20国侵蚀地形特征（如高程、坡度、坡度等宏观分布和微观格局）的基础数据，对于该地区地貌特征、地质灾害特征的分析，也具有参考价值。

Slope Length and Steepness Factor (LS) Dataset for 20 Countries along the Belt and Road Initiative. This dataset is derived from publicly available 1-arcsecond resolution SRTM digital elevation data (Shuttle Radar Topography Mission, SRTM; http://srtm.csi.cgiar.org), and was preprocessed through steps including edge stitching removal, false stripe elimination, and filtering denoising. The 7.5-arcsecond resolution LS factor maps were generated using the LS factor algorithm from the Chinese Soil Loss Equation (CSLE) model and the LS_Tool developed in this project. The LS factor data for the 20 countries along the Belt and Road Initiative is a necessary dataset for calculating soil erosion rates based on CSLE, as well as a foundational dataset for analyzing eroded terrain characteristics (such as the macro-scale distribution and micro-scale patterns of elevation, slope, slope, etc.) of these countries. It also provides reference value for the analysis of geomorphic features and geological hazard characteristics in this region.
