　　报告题目：Dynamic Crop Models and the AgMIP Project

　　报 告 人：Daniel WALLACH博士

　　报告时间：10月08日10:00-11:30

　　报告地点：国际交流中心208会议室

　　报告摘要：

　　This talk will begin with an introduction to dynamic crop models, explaining why they are so important in agronomy (because of the need for methods of generalizing field experiments), but also the problems associated with these models. In particular, they probably have fairly large errors, but it is difficult to evaluate the models because of the scarcity of data.

　　The AgMIP project is a large international project on agricultural model intercomparison and improvement which has brought a new tool for evaluation of crop model uncertainty. This project has made possible the comparison of multiple crop models; the variability between models gives an estimate not previously available of the uncertainty in model predictions.

　　Dr. Wallach will then discuss some of the AgMIP results for wheat, and what we have learned from them about the uncertainty in crop model predictions. Finally, he will give his personal view about some future directions in crop modeling.

　　报告人简介：
Dr. Wallach earned his Ph.D. from Harvard University in Chemical Physics. But he later decided to change fields, and became involved with crop modeling. His early work in modeling convinced him that more rigorous methods of working with these models are required, and that statistics can supply the basis for these methods. He has since specialized in the application of statistical methods to crop modeling. He is the first author of the book “Working with dynamic crop models”. The Second Edition of this book will come out toward the end of this year.
