| Abstract: | 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. |
| Keywords: | food output fluctuant period Henan province |
