Abstract
Based on the analysis of cultivated land,grain production and grain demand in Sichuan Province from 2010 to 2021,the paper constructs the grain security model of Sichuan Province and analyses the degree of grain self-sufficiency in the whole province,and the current situation of food security level in Sichuan Province and its cities(prefectures)was obtained.At the same time,through the construction of cultivated land demand calculation model,taking each city(state)as the unit,based on the grain demand level and grain supply level forecast,under the condition of satisfying the basic self-sufficiency and the complete self-sufficiency,this paper quantitatively analyzes the demand of cultivated land for food security in Sichuan Province,seeks the optimal cultivated land protection area,and puts forward proposals on cultivated land protection and management.关键词
