【摘要】 本文以具体资料为依据,应用数学模式计算出广东省2000年主要农作物产量及耕地面积、人口的预测值,并以略低于日本80年代初的消费水平作为食物结构标准,采用线性规划方法,分别建立了2000年我省封闭型和开放型两种结构模型,求算出对应于这两个模型的最大人口承载量。其结论是:在自给自足的封闭系统内。2000年广东省人口承载力为5876万人;在有选择的开放结构内,其承载力为6215万人。文章并对2000年的供需平衡及提高土地承载力对策进行了讨论。更多还原

【Abstract】 According to the specific data, the predictive values of the yields of main crops, cultivated areas and population in Guangdong province in 2000 are calculated by using mathematical model in this paper. In order to calculate the greatest bearing capacity of land, the structure models of closing type and opening type are set up respectively. The consumption level which is slightly lower than that of Japan in early 1980’s is taken as a standard of the food structure and the linear programming method is applied in it. The conclusion is that the bearing capacity of land in Guangdong Province in 2000 is about 58.76 million persons in the closing type system and about 62.15 million persons in the opening one. The countermeasures on the balance of supply and demand and improvement on the bearing capacity of land in 2000 are discussed in detail.更多还原
