本文在城市化与环境耦合关系模型的理论基础上，结合兰州市实际情况，通过构建城市化综合指数和生态环境综合指数的指标体系，根据耦合关系模型，对兰州市城市化与生态环境耦合演化的趋势进行量化分析，依此来反应兰州市城市化与生态环境的问题。耦合结果显示：兰州市城市化与生态环境耦合程度较低，主要表现为拮抗期，处于中等发展阶段，城市化滞后于环境发展，表明兰州近几年环境治理与保护程度提升。%In this paper, the theoretical basis of the relationship between urbanization and environmental coupling model, combined with the actual Lanzhou, by some indicators, the relative standard configuration values for the vari⁃ables were standardized, and finally coupling evaluation, in 2009 to 2013 in Lanzhou City Urbanization and Environ⁃ment coupling a brief analysis, and so to the reaction in Lanzhou city urbanization and ecological Environment. The results show that the coupling: lower degree of urbanization and ecological environment coupled Lanzhou, mainly as antagonistic stage, in the middle stage of development, urbanization lags behind in environmental development, indi⁃cating Lanzhou environmental management and protection in recent years has been improved.
