Abstract:

With the rapid development of economy and propulsion of industrialization and urbanization, agriculture problems are becoming increasingly obvious. It becomes particularly important that we take a research of regional food security measure and then establish a rational model of regional food security measure.This paper established a comprehensive model of regional food security measure based on the agricultural production fluctuation coefficient, minimum per capita arable land area, cropland pressure index. Taking Shilin town at Wansheng District of Chongqing as an example, we carried on dynamic research and forecasting in its development level of regional plant production by the model. The results show that the food safety factor in regional plant production of Shilin Town is taking in downward rend and such phenomenon may become even worse in the next five years. So we put forwards the corresponding adjust and control measures based on the dynamic analysis and forecasting results.
