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。
According to the inherent contradictions and external factors that affect the economic pressure of the population, this paper determines the evaluation index system reflecting the regional population economic pressure and calculates the stress index by principal component analysis. Finally, by means of cluster analysis and other methods, The Spatial Structure Evolution of Population Economic Pressure. The results show that: from 1990 to 2005, the spatial pattern of population economic pressure in Gansu Province has obvious regional characteristics, which are characterized by more developed economy, better natural resource conditions, slower population growth and higher population quality. Its population economy On the other hand, the pressure on the population economy will change greatly. In addition to the pressure brought by the population itself, the slow economic development is an important factor that can not be ignored.
