摘　　要：科学分析城市土地集约利用长期变化规律对于保护土地资源、完善城市土地管理有着重要意义。本文通过层次分析法和信息熵权法综合确定评价指标体系权重,运用灰色关联综合评价法分析了1990～2006年芜湖市土地集约利用水平变化规律。结果表明:(1)评价指标权重应主观和客观相结合确定;(2)芜湖市土地集约利用制约因子主要是经济效益因子和生态效益因子;(3)芜湖市1990～2006年土地集约利用水平总体上处于上升状态,但期间有3次波动,呈波浪式变化形态。Scientific analysis of long-term mutative law on urban land intensive utilization has great significance for the protection of land resources and improving land management. This paper confirms a comprehensive weight of evaluation index system by the AHP and the information entropy-weight method, then handle grey relational evaluation synthetic model for mutative law on land intensive utilization from 1990 to 2006 in Wuhu. The results indicate that： （1） The weight of evaluation index should confirm by combination of subjective and objective methods;（2） the main restricting factors of land intensive utilization are economic benefit factor and ecological benefit factor in Wuhu; （3） the level of land intensive utilization has been improving from 1990 to 2006 in Wuhu, but has three fluctuations and presents undee mutative shape in the mass.
