AnnAGNPS is a watershed-scale hydrological model designed to analyze the impact of nonpoint source pollution in agricultural environments. Its unique capabilities have defined it as an essential model that is used globally to evaluate agricultural management scenarios. However, it does not currently have a user-friendly graphical interface that provides a simple way for users to perform simulations. This article presents QAnnAGNPS, a plugin developed in QGIS to facilitate access to the simulation capabilities of AnnAGNPS through a user-friendly interface and the addition of extra features, including data visualization. QAnnAGNPS, in addition to fulfilling this valuable task, opens the door to the incorporation of additional functions already included in other similar hydrological models. The plugin has been tested in the Latxaga cereal basin in Navarra, Spain, and has demonstrated that it provides a simpler way to perform simulations and visualize results compared to AnnAGNPS.

AnnAGNPS是一个流域规模的水文模型，旨在分析面源污染对农业环境的影响。其独特的功能使其成为全球范围内用于评估农业管理场景的重要模型。然而，它目前没有一个用户友好的图形界面，为用户提供执行模拟的简单方法。本文介绍了 QAnnAGNPS，这是一个在 QGIS 中开发的插件，旨在通过用户友好的界面和添加额外功能（包括数据可视化）来方便访问 AnnAGNPS 的模拟功能。QAnnAGNPS 除了完成这项宝贵的任务外，还为合并其他类似水文模型中已包含的附加功能打开了大门。该插件已在西班牙纳瓦拉的 Latxaga 谷物盆地进行了测试，并证明与 AnnAGNPS 相比，它提供了一种更简单的方法来执行模拟和可视化结果。
