Abstract:

Preliminary quantitative analysis of 16 indicators for 10 cities on northern slope of Tianshan Mountains(NSTM)is presented. By using the principal component analysis method, urban niche breadth model, and differentiation index model, niche breadth and differentiation characteristics of the urban agglomeration are measured and calculated. It is clear that the urban niche breadth of the primary city of urban agglomeration in NSTM is high while the indexes of other major cities are low, and the polarization is obvious. The comprehensive differentiation index of urban niche breadth shows first a decreasing tendency and then an increasing tendency,and the accumulative effect is enhanced. The niche breadth differences in economy and public service between the cities are apparent, while the niche breadth difference in infrastructure status is not so significant.

Key words: urban multidimensional niche, niche breadth, principal component analysis, urban agglomeration on NSTM
