中国西北地区人口承载力及承载压力分析

Analysis of the Population Carrying Capacity and Carrying Pressure in Northwest China

本文从水资源角度出发,通过一定的计量分析,探讨了西北地区的水资源人口承载力及其动态变化,并结合人口规模预测,进一步研究了西北地区人口对资源和环境的压力状况。研究发现,西北地区人口承载力较低,但今后会进一步有所上升,与人口变动相比,人口超载现象将始终存在,但是程度将略有降低。

Using metrological analyzing method, the paper water resource in northwest China and its dynamic variation, probes into the population carrying capacity of it also makes a population scale forecast and the pressure that brought to resources and environment by the increase of population . The research shows that the population carrying capacity in this area is relatively low, but will increase, while the phenomena of population overcapacity will decrease slightly, it will always exist comparing to the change of population.
