摘　　要：土地集约利用评价研究能够有效推进土地节约集约利用,为我国发达地区城市土地集约利用提供科学依据.以构建的基于压力-状态-响应模型(PSR)的城市土地集约利用评价指标体系为基础,运用熵权法计算权重,采用障碍度模型进行障碍因子诊断,对苏州市土地集约利用进行综合评价,结果表明:①2008-2017年,苏州市土地集约利用总体呈波动上升趋势,压力、状态、响应3个子系统得分不断上升,但三者增长率差异显著.②指标层第一障碍因子由地均社会消费品零售额向人均建设用地转变,苏州市土地集约利用的核心因素由经济发展因素向人口压力转换.③压力、状态系统的障碍度处于增长态势,土地状态系统是阻碍苏州市土地集约利用水平的重要因子.In order to further promote the economical and intensive use of land in Suzhou and to provide a scientific basis for the intensive use of land in other developed cities in the east of China,an evaluation index system of urban land intensive utilization based on PSR model was constructed.The weight was calculated with the entropy weight method,and the obstacle factor diagnosis was carried out,using the obstacle degree model to comprehensively evaluate the intensive utilization of land in Suzhou.The results showed thatfrom 2008 to 2017,the overall trend of land intensive use in Suzhou rose in a fluctuating way,and the scores of pressure,state and response were constantly rising,but the growth rates of the three subsystems were significantly different;that the first obstacle factor of the index layer changed from the average retail sales of consumer goods to the per-capita construction land,and the core factor of intensive land use in Suzhou shifted from economic development to population pressure;and that the obstacle degree of pressure and state system was growing,and the land state system was an important factor that hindered the intensive utilization of land in Suzhou.
