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.
