摘　　要：以西安市为例,构建了城市化水平综合指标体系和生态环境综合指标体系,并应用灰色关联度模型及耦合协调度模型对二者关系进行了研究。结果表明:①1996—2010年,西安市城市化水平综合得分不断提高;②西安市生态环境综合水平呈现波动中向良性方向发展的态势;③灰色关联度分析表明,人均耕地面积等生态环境压力指标是影响西安市城市化的最主要因素,而人口密度等社会经济城市化指标是胁迫生态环境的主要原因;④西安市城市化与城市生态环境耦合度的时序变化表现出明显的波动性,耦合度以颉抗阶段为主,耦合协调度基本处于中高度协调水平。Xi′an was Taken as an example.The urbanization level comprehensive index system and the ecological environment comprehensive index system of Xi′an were established.The results showed that： ① from 1996 to 2010,the urbanization level of Xi′an continuously improved over the time;② ecological environment of Xi′an developed with a fluctuation pattern,however,the general trend became better and better;③ by gray relational analysis,it can be concluded that ecological environmental pressure index such as the cultivated land area per capita,was the main factor which affects urbanization of Xi′an,and social economy urbanization indicators such as population density,were the main reason for the ecological environment stress;④ urbanization and the coupling degree of ecological environment was fluctuation over the time.The coupling degree mainly antagonized the stage,basically at the high level of coordination.
