中文摘要：
介绍了典型作物生长模型的特点及在水文水资源领域应用中存在的问题，讨论了该模型在水文水资源领域的开发应用前景。结果表明，分布式水循环（水文）模型和作物生长模型的耦合研究有助于探索作物产量预报的新方法、提高作物模型预报准确率，为研究作物种植结构对水文系统的影响及水土资源的高效利用提供了数据支持。
英文摘要：
The characteristics o{ main crop growth model were introduced, and its applications in the field of hydrology and water resources, as well as the existing problems, were showed. Furthermore, the development and application prospects were discussed. It is revealed that the coupled study between distributed water cycle （hydrology） model and crop growth model will he in favor of not only exploring new methods of crop yields prediction and improving the prediction accuracy of crop model, but also studying on the influence of crop cultivation structure on the hydrological system, as well as the efficient use of land and water resources, which will provide the scientific data support for the ecological environment construction and sustainable development strategy.
