以天山北坡经济带11市县的城乡区域系统为研究对象,采用主成分分析法对该区域城乡关联发展水平进行了定量评价,以期为天山北坡经济带城乡区域系统的协调发展提供依据。研究表明:城乡关联度与城市化水平和人均GDP有着密切关系,呈正相关性;天山北坡经济带城乡关联发展水平具有显著的等级和空间差异;而且,采用主成分分析法对天山北坡经济带城乡关联度的量化分析与与该区域城乡关联发展的实际水平基本相符,表明主成分分析法对城乡关联发展的定量分析是可行的。
Taking the urban and rural area system of 11 cities and counties in north Tianshan Economic Belt as the research object, this paper uses principal component analysis (PCA) to quantitatively evaluate the development level of urban-rural linkages in this area, in order to provide a basis for the coordinated development of urban and rural areas in North Tianshan economic belt. The research shows that the correlation degree between urban and rural areas is closely related to the urbanization level and the per capita GDP, and is positively correlated. The level of urban-rural association development in the northern Tianshan economic belt has significant level and spatial difference. Moreover, The quantitative analysis of the correlation between urban and rural areas is basically in line with the actual level of urban and rural development in the region, indicating that the principal component analysis is feasible for the quantitative analysis of the urban-rural development.
