| 摘 要： | 文中根据影响人口经济压力的内在矛盾和外在因素,确定了反映区域人口经济压力的评价指标体系,并采用主成分分析法计算其压力指数,最后通过聚类分析法等方法定量分析了甘肃省人口经济压力的空间格局演变特征。结果表明:1990~2005年间,甘肃省人口经济压力空间格局具有明显的地域特征,其特征表现为经济较发达、自然资源条件较好、人口增长较慢、人口素质较高的地区,其人口经济压力变化小;反之,人口经济压力变化就大,除人口自身带来压力外,经济发展缓慢是不可忽视的重要因素。

| Abstract: | According to the internal contradictions and external factors which affected the population-economy stress,the evaluation indicators were confirmed.Then the principal component analysis was adopted to calculate the population-economy stress index.Finally through using the clustering analytical method,the spatial pattern changing characters of the population-economy stress in Gansu Province were analyzed quantificationally.The results showed that the spatial pattern of the population-economy pressure had obv... |
