| 摘 要： | 利用主成分分析方法和聚类分析,对祁连山北坡牧区人口经济压力空间格局进行了研究。结果表明:祁连山北坡牧区人口经济压力空间格局具有明显的地域特征,其特征表现为牧区西段经济较发达、自然资源条件较好、人口增长较快,人口经济压力小;东段自然植被较好,经济开发不足,人口经济压力相对较大;中段随着经济进一步发展,表现出人口经济压力由低到高的特征。

| Abstract: | In this study,we investigated the spatial distribution pattern of population-economic pressure in the Qilian Mountain northern slope pastoral area by employing principal component and cluster analyses.The results indicated there were striking regional characteristics in the spatial distribution pattern of population-economic pressure in the research area.The specific performances indicated the following.The western region had advanced economies,high population growth rate,and population economic pressure was small.The population-economic pressure here showed a negative correlation.The eastern region had a poor natural environment.The population-economic pressure here showed a positive correlation,and population economic pressure were large.In the central region,the population-economy pressure indexes showed a negative to positive correlation with the developing economy. |
