作物模拟模型是研究复杂作物系统的重要方法之一，是一项新的农业信息技术。构建良好的作物生长发育模型，不但可以预测作物 在不同的环境条件下模型参数大多需要重新估计和优化。作物生长模型的优化是高维、非线性的复杂优化问题，这无疑增加了作物模型的建立的难度。 -Crop simulation models is to study the complex and important ways cropping systems is one of a new agricultural information technology. Build a good crop growth and development model, not only can predict the crop in different environmental conditions, most need to re-estimate the model parameters and optimization. Optimization of crop growth models is a high-dimensional, nonlinear complex optimization problems, which undoubtedly increased the difficulty of crop model.
