摘要:

对四川省的粮食安全现状进行评估,探索耕地保护机制和管控措施。通过对四川省2010—2021年耕地规模、粮食生产和粮食需求状况进行分析,构建四川省粮食安全模型,分析全省粮食自给程度,评估四川省及其各市/州粮食安全现状水平。同时,通过构建耕地需求量测算模型,以市/州为单元,基于粮食需求水平与粮食供给水平的预测,在满足基本自给和完全自给的条件下,对保障四川省粮食安全的耕地需求量进行定量分析,寻求最优耕地保护面积,提出耕地保护与管控建议。研究表明,目前四川省耕地资源数量可以实现粮食基本自给,全省粮食安全状况良好,但根据粮食自给率预测未来耕地需求量增大,耕地保护压力较大,应采取相关管控措施。

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.

Key words: food security, farmland demand, farmland protection, Sichuan Province
