土壤侵蚀模型地形因子计算工具（2.0版）

该软件为土壤侵蚀模型地形因子计算工具2.0版本，2.0版本在1.0版本的基础上修改了当坡长大于临界坡长后的坡长因子算法。2.0中用整坡坡长因子计算公式计算此时的坡长因子值。该软件用于计算土壤侵蚀的坡度坡长因子。本软件有 32 位和 64 位系统计算机两个版本。本次发布的是64 位系统，64 位版本一次性可计算完成 4万行×4 万列区域的 LS 因子，如计算栅格大小按 10m 计算，能计算160 000km 2 的区域。软件的开发环境为 Visual Studio 2010，模型算法由 C++语言实现，软件界面使用 C#语言实现，文件读写用开源库 GDAL 来实现。图形显示不依赖任何第三方图形库。文件包中包括软件工具及详细的软件使用说明手册。 本软件属于免费使用软件，但希望用户在使用过程中能够反馈使用状况，使用过程中遇见问题、意见和建议等。反馈意见将对进一步优化、改进程序有重要意义。

This software is the Soil Erosion Model Topographic Factor Calculation Tool version 2.0. Compared to Version 1.0, Version 2.0 revises the slope length factor algorithm for scenarios where the slope length exceeds the critical slope length. In Version 2.0, the slope length factor value in such cases is calculated using the formula for the slope length factor of the entire slope.

This software is designed to calculate the LS (slope length and steepness) factor for soil erosion. It has two versions for 32-bit and 64-bit computer systems respectively. The 64-bit version released this time can complete the calculation of the LS factor for a region of 40,000 rows × 40,000 columns at one time. If the grid cell size is set to 10 meters, it can cover a region of up to 160,000 km².

The software was developed using Visual Studio 2010 as the development environment. The core model algorithm is implemented in C++, the software interface is developed with C#, and file I/O functions are implemented using the open-source library GDAL. The graphical display function does not rely on any third-party graphics libraries.

The distribution package includes the software tool and a detailed user manual. This software is free-to-use. We sincerely hope that users will provide feedback on their usage experience, including any encountered problems, opinions and suggestions during use. Such feedback will be of great significance for further optimizing and improving the program.
