摘　　要：以干旱区生态城市兰州市的不同功能模块为研究对象,在各模块污染指数和适宜度指数的基础上,运用生态位理论和方法,分析了2002—2006年兰州市不同功能模块生态位格局变化规律.结果表明,大气、水和声环境的污染生态位呈下降趋势,城市绿化适宜度生态位呈上升趋势,自然生态环境系统明显改善;第三产业模块生态位上升趋势明显,第二产业模块生态位处于较高水平,而第一产业模块生态位变化不大,经济系统的产业格局逐步趋于合理;社会基础设施、社会资源配置和社会生产与保障模块均呈上升趋势,只有人口模块呈下降趋势,社会系统在较低水平上呈发展趋势.Based on the niche theory and method, this paper studied the development of different urban functional modules and discussed the rules of niche pattern change of different functional modules in Lanzhou City from 2002 to 2006. The results showed that： （1） The urban virescence niche increased, while the atmospheric niche, water niche and sound niche had a decreasing trend. It proved that the natural environmental system is improved significantly. （2） The tertiary industrial niche went up, and the secondary industrial niche came down, but the primary industrial niche had a little change. The structure of industry was more and more reasonable. （3） Social basic establishment suitable niche, social resource distribution suitable niche and social production and insurance suitable niche increased, but only population suitable niche went down in social system.
