| 摘 要： | 本文首先应用小波分析方法对中国大豆生产的基础数据进行滤波计算，消除偶然因素的噪声对大豆生产数据的影响，消噪后的数据更能反映中国大豆生产发展变化规律。根据消噪后的数据将1950～2005年中国的大豆生产情况分为8个周期，并计算了每个周期的波峰、波谷、平均产量和振幅等指标，完成了中国大豆生产的变化周期规律研究。在此基础上，对形成大豆生产波动规律的成因进行了分析。

| Abstract: | In the paper the base data of soybean production of China is calculated for filter by Wavelet Analysis Theory, the yawp of incidentally factors in the data of soybean production is eliminated, the data those yawp has been eliminated may reflect the rule of soybean production in China. According to the data those yawp has been eliminated, the soybean production of China for 1950 to 2005 is divided into 8 cyclic fluctuation, the wave crest, trough, average yield and swing are calculated, the research of the soybean production＇s rule in China is completed; then we have analyzed the reason forming the rule of soybean production cyclic fluctuation. |
