摘要
利用1951—2005年河南省粮食产量统计数据,应用波动理论和周期理论分析河南省粮食产量波动规律,考察河南省粮食产量波动的历史过程和数量特征.结果表明,河南省粮食产量波动具有短周期的显著特征,平均波动周期3.3年左右,波幅较小,扩张期略长于收缩期.
It reviews the history process and quantity characteristic of food output fluctuating in Henan province and analysis fluctuating rule of food output applying fluctuating theory and period theory with food product statistic data from 1951 to 2005. The results show the food output fluctuating has the notable characteristic of short period, periodic fluctuations in the average 3.3 years, small amplitude, is a rather long period of expansion in systolic.
