摘要

根据青海湖地区土地资源和人口现状与特点

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6.96×10

人

其中耕地为4.84×10

人

草地为2.13×10

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3.25×10

人

其中耕地为1.81×10

人

草地为1.43×10

人

承载比率分别为55.82%和44.18%。另外

区域各县土地最大适宜人口承载总量和承载量也存在较大差别

且各县的耕地和草地的承载量也存在差异

适宜人口承载量从大到小依次为: 共和>海晏>刚察>天峻。

Abstract

Based on the analysis of land resources and current population status and the characteristics in the Qinghai Lake region

the ultimate and maximal population carrying capacity of land and the pop ulation 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 region is 695973

in which cultivated land is 483720

grassland is 212703

and the corresponding capacity ratios are 69.44 % and 30.56 %

respectively. The total maximal population carrying capacity of land is 324620

in which cultivated land is 181219

grassland is 143410

and the capacity ratios are 55.82 % and 44.18 %

respectively. The maximal population carrying capacity is diffident in each county. Population carrying capacities of Gonghe County

Haiyan County

Gangcha County

and Tianjun County are 7.01756

6. 00874

5.96404

and 0.03318

respectively. The capacity of cultivated land and grassland in each county is also different.
