Dynamic Analysis on Change and System Simulation of Food Production Materials in the Northern Anhui Province

Abstract:

According to statistical and survey data at provincial levels, trend of Grain per unit area yield materials and its influencing forces in Northern Anhui Province during the last 20 years were discussed in this article. It was found that: since 1991, the total Grain per unit area yield materials availability took on increasing, but regional difference was very obvious in Northern Anhui Province; Suzhou City and Huaibei City with higher rate took on increasing as a whole, inverse to the lower Grain per unit area yield materials in Fuyang City, Bengbu City and Huaian City. Grey correlation analysis showed that the most important factors of Grain per unit area yield materials were the effective irrigated area, net income of farmer per capita and financial support to agriculture. However, the influence of natural disaster and pesticide application amount should not be ignored.
