内蒙古自治区水资源人口承载力动态分析

The Dynamic Analysis of the Population Carrying Capacity of Water Resources in Inner Mongolia

为了评价人口压力对水资源环境的影响程度,将水资源生态足迹模型运用到人口承载力研究中,计算了内蒙古自治区各个盟市2008-2013年的水资源人口承载力.得出结果:(1)2008-2013年期间,除了呼伦贝尔市和兴安盟,内蒙古其他盟市的实际人口都超出了水资源人口承载力上限,出现了人口超载.(2)水资源人口承载力与水资源承载力呈正相关;水资源人口压力指数与人均水资源生态足迹呈正相关.结论:内蒙古各个盟市历年水资源人口压力指数呈现波动上升趋势,说明这些地区水资源环境受到的人口压力在不断加剧.

In order to evaluate the influence of population pressure on water resources and environment, the Water Ecological Footprint model is applied to the analysis of the population Supporting Capacity, and the Population Supporting Capacity of Water Resources in autonomous leagues and cities in Inner Mongolia Region from 2008 to 2013 is calculated. The results showed that： （1）During 2008 - 2013, except the Hulunbeir city and Xing＇an league, the actual population of other unions and cities in Inner Mongolia have all surpassed the upper range of the Population Supporting Capacity of Water Resources, that is to say, their population is overloaded. （2）The Population Supporting Capacity of Water Resources is positively related to the Carrying Capacity of Water Resources, in the same way the Population Pressure Index of Water Resources and the Ecological Footprint per capita Water Resources are positively related. It is concluded that the Population Pressure Index of Water Resources in these cities is rising in the past years, which indicates that the pressure of population upon the water resources environment is incessantly increasing.
