摘　　要：地质生态环境是承载城市的重要物质基础,与城市发展存在极其复杂的关系,从时间和空间层面上对二者演进趋势、时序规律和空间分异差异进行归纳和认识有助于促进地质生态环境与城市化协调发展。首先构建地质生态环境与城市化的指标评价体系,利用SPSS21.0软件分别获得了1990—2015年重庆市地质生态环境与城市化评价指标的主成分权重系数,及2015年重庆市38个区县若干地质生态环境指标水平与人口密度、人均GDP、城市空间发展强度、工业综合能耗等城市化指标水平的皮尔逊相关系数。借助关联耦合分析方法,从时间和空间层面获得了重庆市地质生态环境与城市化的关联度、耦合度和协调度大小。结果表明:经济城市化和绿化生态水平分别对城市化系统和地质生态环境系统的贡献份额最大; 1990—2015年重庆市地质生态环境与城市化的耦合协调水平呈现持续增长态势,关联度、耦合度和协调度从低关联—低水平耦合—严重不协调—城市化发展滞后,过渡到高关联—高水平耦合—高级协调—地质生态环境滞后阶段; 2015年重庆市38个区县地质生态环境与城市化的关联度、耦合度和协调度都存在显著的分区差异,渝西较发达地区的耦合协调程度普遍高于渝东北和渝东南远郊欠发达地区,区域经济发展水平与耦合度、协调度存在很大的空间对应关系。正确辨识地质生态环境与城市化耦合协调关系的时空演化规律和特征,通过城市规划的主动干预作用,采取适当的城市发展政策和环境保护战略对促进地质生态环境与城市化的协调可持续发展具有重要意义。Geo-ecological environment is the important material basis for cities,and has extremely complex relations with urban development.Summarizing the evolution trend,time rules and spatial differences from the aspect of time and space contributes to the coordinating development of geo-ecological environment and urbanization.An index evaluation system of the geo-ecological environment and urbanization was first constructed.The main component weight coefficient of the geo-ecological and urbanization evaluation index of Chongqing from 1990 to 2015,and the Pearson correlation coefficient of geo-ecological environment index level and population density,per capita GDP,urban spatial development intensity,industrial comprehensive energy consumption and other urbanization index levels of the 38 districts and counties of Chongqing for 2015 were respectively obtained using the SPSS 21.0 software.Using the correlation coupling analysis method,the correlation degree,coupling degree and coordination degree of the geo-ecological environment and urbanization in Chongqing were obtained at time and space levels.The results showed that the economic urbanization and greening ecological level made the largest share of contribution to the urbanization system and the geo-ecological environment system,respectively.From 1990 to 2015,the coupling and coordination relationship between the geo-ecological environment and urbanization in Chongqing had shown a continuous growth trend,and the correlation degree,coupling degree and coordination degree had transitioned to a high correlation-high level coupling-high level coordination-geo-ecological environment lagging stage from low correlation-low level coupling-serious in coordination-urbanization development lagging.Furthermore,the correlation degree,coupling degree and coordination degree of the geo-ecological environment and urbanization in the 38 districts and counties of Chongqing for 2015 had undergone significant regional differences.Moreover,the degree of coupling coordination in more develo
