摘要
应用灰色系统理论的ＧＭ（１，１）模型分别对云阳县人口、耕地、粮食等进行了预测，并对预测结果进行了分析。同时对影响云阳县粮食产量的行为因子也进行了关联分析，提供了解决云阳县人口－耕地－粮食复合系统供求矛盾的若干政策措施。
GM(1,1) model of the grey theory was applied to the forecast of the development of population, cultivated land and grain production in Yunyang county, Chongqing, and the results were analysed. In addition, correlation was made of various behaviour factors influencing grain production in the county. Some countermeasures for solving the contradictions between supply and demand in the population cultivated land grain complex of the county are proposed.
