模拟补给区喀斯特泉排放和土地利用变化的影响是世界上许多国家水资源管理的重要战略内容。我们通过将最近提出的LuKARS（喀斯特系统土地利用变化建模）模型集成到FREEWAT（水资源管理免费和开源软件工具）框架中，引入了一个用户友好的建模环境。LuKARS是一个喀斯特系统的降雨-排放模型，通过改变主要水文单元（即具有均匀土壤和土地利用性质的景观单元）的面积来模拟土地利用变化的影响。FREEWAT是一个在QGIS桌面应用程序中实现的水资源管理的免费开源工具包。将LuKARS集成到FREEWAT中，利用GIS功能来绘制、可视化和更改相关的水文形状文件。FREEWAT为预处理和后处理工具提供了一个模块化框架，方便了LuKARS模型的设置、校准、分析、存储和共享。
Simulating karst spring discharge and land use change impacts in a recharge area is strategic for water resource management in many countries worldwide. We introduce a user-friendly modeling environment by integrating the recently proposed LuKARS (Land use change modeling in KARSt systems) model into the FREEWAT (FREE and Open Source Software Tools for WATer Resource Management) framework. LuKARS is a rainfall-discharge model for karst systems that simulates the impact of land use changes by changing the area of dominant hydrotopes, i.e. landscape units with homogeneous soil and land use properties. FREEWAT is a free and open source toolkit for water resource management implemented in QGIS desktop application. The integration of LuKARS into FREEWAT takes advantage of the GIS capabilities to map, visualize and change the relevant hydrotope shapefiles. FREEWAT provides a modular framework for pre- and post-processing tools that facilitate the setup, calibration, analysis, storage and sharing of LuKARS models.
