我国国家级农业气象产量预报科研业务进展

回顾、总结了近年来我国国家级农业气象产量预报科研和业务方面的主要进展。几年来，在产量序列的分解和产量预测方面有所发展，并逐步开发模拟模式在产量变化分析和预测中的应用。在业务建设方面，不断充实历史资料数据库，加强通讯网络建设，并研制了新一代产量预报业务系统（ＷＡＹＰＳ），业务服务水平有了较大提高。

The Advances of the Studies and Operational Work of the State-level Agrometeorological Crop Yield Predictions in China

The advances of the scientific research and operational work of the state-level agrometeorological crop yield prediction of . China were recalled and summarized. Some progress were made in the crop yield sequence separation and prediction,including the- attempt of using crop growth simulation models for crop yield prediction. In operational respect,historical database was expanded and a real-time communication network was established. A new version of software system for crop yield prediction (WAYPS) was developed,and the level of operational service was improved greatly.
