Abstract:

This paper, from connotation definition of the urban land intensive use based on sustainable development, establishes an index system to evaluate the urban land intensive use among nine cities in Fujian province, applies principal component analysis and entropy method to calculate their scores, and adopts clustering method to classify their intensive use levels. The results indicate that the urban land intensive use degree is highest in the southern coastal cities, moderate in the central Fujian province and low in the northern, due to a difference in their industrial structures, and that the urban land intensive use has a ladder-shaped spatial distribution due to their locality conditions. This paper analyzes the spatial difference on Fujian’s urban land intensive use and offers reference for evaluating urban land intensive use and reserve.

Key words: ustainable development, intensive use, spatial difference, Fujian province

摘要：

通过对基于可持续发展的城市土地集约利用内涵的界定，建立了基于可持续发展的城市土地集约利用指标体系，对福建省9个地级以上的城市进行城市土地集约利用评价，综合运用主成分分析法和熵值法，计算得出各个城市土地集约利用的分值，并尝试用聚类方法对福建省城市土地集约利用水平划分类别，并对结果进行分析，探究其原因。结果表明：1)靠近沿海的南部城市土地集约利用程度最高，中部城市次之，北部城市土地低度利用，这是由城市产业结构的差异造成的；2)在福建省省域空间上，城市土地集约利用呈阶梯状分布，这主要是由区域区位优劣造成的。通过对福建省城市土地集约利用空间差异的分析研究，反映了该区域城市土地集约利用的空间差异，为城市土地集约利用评价和城市土地储备提供了有益参考。
