Abstract: With the less land areas and large populations,Fujian province has become the third largest food demand area in china.Under the background of rapid urbanization,the contradiction between grain production and demand of food consumption is becoming more and more intensified.In this paper,we built an integrated index of regional food security,including the food self-sufficiency rate,per capita share of grain,grain production levels,per capita arable land,and fluctuation coefficient in grain production.Then we evaluated the food security of all the cities in Fujian province in both 2006 and 2012using the coefficient of food security method.The results showed that:(1)the food security situation in Fujian Province was in criticality safety level and the overall food security could be guaranteed.But the downward pressure of food self-sufficiency rate was increasing;(2)there were obvious differences among food security of various regions,severe deterioration could be proved in the coastal areas according to the changing trends;(3)based on the food security evaluation scores(Q value),nine cities in Fujian was divided into three types:regions of food security,including Sanming,Nanping and Longyan;regions of critical food safety,including Zhangzhou and Ningde;regions of food insecurity,including the other cities.Finally,according to different types of food security and consumption characteristics in nine cities,we proposed some policy suggestions to ensure regional food security of Fujian province.
