摘要
重庆粮食生产总量呈现下降趋势,产量与消费量、实际储备量与应储备量均有较大缺口,同时又面临耕地面积减少的困境;因此,提高粮食单产是重庆实现粮食增产的最佳途径。通过主成分分析,各种生产要素的投入和抗灾能力的大小是影响重庆粮食单产的主要因素。
On the basis of decreasing total production rate of grain, insufficiency in production rate and consumption rate and storing rate and reasonable storing rate and decreasing plot areas, this paper holds that increasing per unit yield of grain is the best path to increase grain production rate. By using main component analysis, this paper holds that main factors to influence per unit yield of grain are investment of all factors and anti-disaster capacity.
