摘　　要：从经济、社会、生态3个方面建立了评价指标体系,采用综合集成赋权法确定各评价指标权重,运用TOPSIS评价模型对1997～2007年重庆市的城市土地利用效益进行评价。结果表明,1997～2007年土地利用综合效益的相对接近度从0.1240增加到0.8988,年均增幅达7.75%;同时,根据相对接近度的变化情况,土地利用效益呈现"波动(1997～2000年)、较快(2001～2005年)、放缓(2006～2007年)"3个明显的阶段。在此基础上,针对重庆市城市土地利用效益问题提出了几点建议。The evaluation indicator system of land use in Chongqing was established from the aspects of economy, society and ecology. Applying the method of comprehensive synthetic approach, the weight of each indicator was defined. Using TOPSIS evaluation model, urban land use benefits in Chongqing were calculated. The results showed that the opposite near degree of Chongqing＇ s integrative efficiency of urban land use was increased from 0. 124 0 to 0. 898 8 from 1997 to 2007. And it presented three apparent developmental stages, just from 1997 to 2000, from 2001 to 2005, from 2006 to 2007. Based on the state of urban land use efficiency in Chongqing City, a set of suggestions were put forward so as to relieve the state.
