摘　　要：城市土地是城市社会和经济发展的基础,其利用水平的高低会给城市带来不同的经济、社会和环境效益。运用RS,GIS的空间分析手段,得出乌鲁木齐市近8 a来建成区发展演变图,并对土地总体集约利用趋势分析。利用多因素评价法建立潜力评价指标模型体系,通过AHP法得出各评价因子权重,建立潜力分级体系,对指标进行定量标准化处理,分别加权确定最终潜力值及值域。结果表明:乌鲁木齐市对应的城市土地集约利用潜力值是3.26,属于第3级,相对粗放利用,在当前的经济社会条件下,尚有潜力可挖。Urban land is the base of urban social and economic development,the different land intensive utilization brings us different economic,social and environmental benefits. We obtain the picture of built-up area＇s evolvement tendency of Urumqi city in recent eight years based on RS ＆ GIS and analyze the tendency of urban land intensive utilization. We construct a model of indicator system for evaluating urban land potential. Through AHP method obtaining weights of each evaluation factors and constructing a system of gradation for potential,we make indicators standardization and get the range of potential and value. The results show that the potential value of urban land intensive utilization in Urumqi is 3.26 and it falls into band 3. It has potential to develop in the current.
