| Abstract: | Based on collecting of meteorological cereal crop yield forecasting models and quantitative analysis of meteorological cereal crop yield affecting factors, the configuration of meteorological factors are classified according to the different areas by methods of clustering analysis. The primary and secondary meteorological factors affecting major cereal crop yields in different areas of China and their affecting periods are found and discussed thoroughly. The conclusions can be used for forecasting of the large-area cereal crop yields . |
