【摘要】：[目的]通过分析农业资源与环境要素的效用,探讨保障我国粮食安全举措。[方法]在我国粮食安全现状的基础上,采用分析法分别对农业资源与环境要素的利用展开研究,提出针对性建议。[结果](1)农业资源要素:耕地资源利用率较低、农业资源浪费严重、农村劳动力大量转移;(2)农业环境要素:自然环境要素利用效率不高、农业投资不合理。[结论]由农业资源与环境要素两大因素导致的粮食安全问题日益突出。基于此应发展"紧凑型"城市化模式、坚持内涵式耕地开发,在减少农业资源浪费的同时提高现有耕地的整体质量;应通过改善基础设施、优化市场准入制度、提升流通效率,以提高粮食市场竞争力;应综合考虑农业资源与环境要素两大因素,从制度层面建立健全粮食安全保障体系。
[Abstract]:Objective: to analyze the utility of agricultural resources and environmental factors and to discuss the measures to ensure food security in China.[methods] based on the present situation of food security in China, the utilization of agricultural resources and environmental factors were studied by means of analytical method, and suggestions were put forward.[results] 1) factors of agricultural resources: low utilization rate of cultivated land resources, serious waste of agricultural resources, large transfer of rural labor force and agricultural environmental factors: the utilization efficiency of natural environment elements is not high, and agricultural investment is unreasonable.[conclusion] Food security problems caused by agricultural resources and environmental factors are increasingly prominent.Based on this, we should develop the "compact" urbanization model, adhere to the connotative development of cultivated land, reduce the waste of agricultural resources and improve the overall quality of existing cultivated land, and improve the efficiency of circulation by improving infrastructure, optimizing market access system, and enhancing circulation efficiency.In order to improve the competitiveness of grain market, two factors, agricultural resources and environmental factors, should be considered synthetically to establish and perfect the grain security system from the system level.
