摘要: 作物生长模型是定量评估作物生产潜力的重要工具。EPIC 模型自1985 年发表后, 以其强大的功能在全球范围内得到了广泛应用。本文简述了EPIC模型的主要结构和功能, 介绍了运行该模型所需的数据及数据库的构建方法, 总结了EPIC模型的主要应用领域以及在中国包括作物生产潜力评估、水分和气候变化对产量影响、养分循环和损失、土壤碳储量变化、土壤侵蚀预测等方面的应用情况, 最后提出了EPIC模型使用时的注意事项和研究展望。

关键词: EPIC模型, 模型参数, 模型应用

Abstract: Crop growth model is a useful tool for quantitative evaluation of crop production potentials. Since itsstudy was first published in 1985, EPIC model has been widely used in the world because of its powerful functionality.In this paper, the main structure, function and data requirements were firstly summarized, and then the model applications in the world and China were reviewed. In China, since the first application in 2001, the EPIC model was used to evaluate crop yield potentials, quantify effects of irrigation and climate change on crop production,estimate nutrient losses and soil carbon storage, and predict soil losses. Finally, a brief discussion and suggestions were given on the model use.
