摘 要:选择青海省重点开发区的26个县、市(区)为研究对象,利用全局主成分分析(GPCA)、聚类分析等方法,根据人口经济活动支撑力、资源供给支持力和生态环境承载力及综合人口资源环境承载力等四个方面对这些地区1999-2012年人口资源环境承载力状况进行了定量、动态评价和分析.指数化的评价结果表明,青海省重点开发区人口资源环境承载力逐年提高,综合人口资源环境承载力指数均值从1999年的-0.29365上升到2012年的0.336723.Taking 26 focus development counties and cities in Qinghai Province as studying object, based on four aspects of support ability of population and economic action holding power of resources bearing capacity of ecology environment and overall carrying capacity, the paper makes quantitative and dynamic assessment on carrying capacity of population resource and environment for every districts from the year of 1999-2012. In which we mainly applied methods of Generalization Principal Component Analysis (GPCA) and cluster anal- ysis Indexed assessment result shows that the carrying capacity of four aspects strengthened gradually in resent years, the mean of comprehensive index increased from -0.29365 in the year1999 to 0.336723 in the year 2012.
