摘要
通过对青海湖地区土地资源和人口现状与特点的描述,估算了该区及各县现实条件下土地资源极限人口承载量和最大适宜人口承载量、草地和耕地所能承担的人口承载量及其比重。结果表明,青海湖地区土地极限人口承载总量为69.5973万人,其中耕地为48.3720万人,草地为21.2703万人,承载比率分别为69.44%和30.56%;区域土地最大适宜人口承载总量为32.4620万人,其中耕地为18.1219万人,草地为14.3410万人,承载比率分别为55.82%和44.18%。此外,区域各县土地最大适宜人口承载总量和承载量存在较大差别,适宜人口承载量(万人)从大到小依次为:共和县(7.0176)>海晏县(6.0049)>刚察县(5.9640)>天峻县(0.0332)。
Based on the analysis of land resources and current population status and the characteristics in the Qinghai Lake area, the ultimate and the maximal population carrying capacity of land, and population carrying capacity of cultivated land and grassland and its proportion in each county are estimated. Results show that the ultimate population carrying capacity of land in the Qinghai Lake area is 695 973, in which the capacity for cultivated land is 483 720 and for grassland, 212 703, with the capacity ratio being 69. 44% and 30.56%, respectively. The total maximal population carrying capacity of land is 324,620, in which the capacity for cultivated land is 181 219 and for grassland, 143 410, with the capacity ratio being 55.82% and 44.18%, respectively. The maximal population carrying capacity is found to be diffident in each county. Gonghe county is 70 176, Haiyan is 60 049, Gangcha is 59 64 0, and Tianjun is 332.
