以分析四川省人口、耕地、粮食系统的现状为基础,选用灰色系统理论的GM(1,1)模型,对2010年四川省的人口、耕地、粮食进行预测。结果表明:2010年,人口将达到8989.6×104人,耕地减少到423.42×104hm2,人均粮食496.9kg,基本实现小康水平,并根据预测结果提出了相应的对策和措施。
Based on an analysis of the current situation of population, farmland and grain of Sichuan Province, this paper, by applying GM(1,1) model of the gray theory, predicts the development of population, farmland and grain of the province by 2010.
