北京市产业结构与生态环境的耦合性问题

基于因子分析法，运用SPASS统计软件，通过建立北京市产业结构与生态环境指标体系，并计算二者的耦合度与耦合协调度，来分析这两个系统的耦合协调发展状况。结果表明，北京生态环境质量有所改善但相对滞后，产业结构不断趋于合理化，经济发展未超出环境的承载能力，耦合状况稳定在高水平耦合阶段，耦合协调水平逐年上升，而且系统的改善情况明显。因此，未来在保证产业结构优化升级的同时，应将重点放在生态环境改善及保护方面。

The Coupling of Industrial Structure and Ecological Environment in Beijing

This paper is based on factor analysis by using SPASS statistical software and establishing Beijing city industrial structure and ecological environment index system. It calculated the coupling degree and coupling coordination degree of the two, to analyze the status of the coupling coordinated development of two systems. The results show that the ecological environment quality in Beijing has improved but is lagging behind and the industrial structure is more reasonable. Besides,economic development does not exceed the carrying capacity of the environment. The two is coupled with stable condition in the high level of coupling stage and the coupling and coordination level increased year by year, and the improvement of the system is obvious. Therefore, we should ensure to upgrade and optimize the industrial structure in the future.At the same time, the emphasis should be placed on improving and protecting the ecological environment.
