影响我国主要粮食作物产量的气象因子研究

Primary Meteorological Factors Affecting Major Cereal Crop Yields in China

通过收集前人主要粮食作物气象产量预报的研究成果 ,将所得到的资料按作物进行分类 ,并进行归一化处理 ,使用系统聚类分析方法 ,以预报方程中的影响因子为指标 ,分区找出各区主要粮食作物产量的主、次要影响因子和影响时期 。

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 .
