摘要: 以土地资源综合体为研究对象,在生产力类型模糊区划的基础上,从土地资源物质能量投入与转化入手,采用科学方法计算了海南岛的土地生产潜力、食物结构和人口承载量.结果表明,海南岛5类土地资源的平均生物生产潜力为5.25×104kg·hm-2,折合标准粮为2.36×104km·hm-2;低中高3种食物结构方案的人口承载量分别为1.9573、1.5481和1.2957×107人口,供养人口为52.5、42.0和34.5人·hm-2.目前人口占各方案可供养人口的比例已分别达到34.2%、43.3%和51.8%,按当前人口增长速度计算到2010年这个比例将达到44.5%、57.5%和68.7%.

Abstract: With the aggregates of land resources as the object of study and based on the Fuzzy regional division of various types of productive forces, the potential land productivity,foodstructure and population Supporting capacity on Hainan Island are computed,with considering the input and transformation of material and energy of land resources.The resultsshow that the average biological production potential of 5 kinds of land resources is 5.25×104 kg·hm-2, equivalent to 2.36×104 kg·hm-2 standard grain. The population supporting capacity based on low, medium and high food structure programmes are 1.9573×107, 1.5481×107 and 1.2957×107 population, or 52.5, 42.0 and 34.5 population perhectare,respectively. At present. the proportion of the population to that be able to provide for support is 34.2,43.3 and 51.8%,and by the year 2010,the proportion will be 44.5, 57.5 and 68.7%, respectively.
