Abstract
This paper studies the correlation between urban spatial morphology and urban comprehensive strength. We select 31 cities with the population over one million in 1990 as our samples. Specifically, we introduce a new clustering methodology, affinity propagation clustering, published in Science in 2007, to cluster urban spatial morphology indicators. Then, using principal component analysis, we evaluate the 31 cities'comprehensive strength in 1990 and 2000, calculate the comprehensive scores and rank the cities for three-level hierarchy.Finally, we test the results of urban spatial morphology clusters and urban comprehensive strength hierarchies by means of Rand Index. Results suggest that the cities which increased comprehensive strength ranking in 2000 are planned more regularly and compactly. In the end, according to the coupling relationship between urban spatial morphology morphology and urban comprehensive strength,we propose some pohcy suggestions for urban planning.关键词
