| 摘 要： | 在阐述城市化与生态环境耦合涵义的基础上,利用协同学思想构建二者之间的耦合度模型,并对1985年以来的中国城市化与生态环境耦合度的时空分布进行了分析。研究结果显示:①从时间上看,中国城市化与生态环境交互耦合的时序基本处于颉颃阶段,且二者的耦合协调度较低;②从空间上看,中国省区城市化与生态环境的耦合度和耦合协调度都明显存在着地域性差异,且耦合协调度表现出东部省区普遍高于中西部省区的规律,同时它还和区域经济发展水平存在很大的空间对应关系;③由于经济发展、历史基础、自然条件和政策影响的差异作用,中国省区城市化与生态环境的耦合强度与耦合协调程度在空间分布上不具有对应性。 |

| Abstract: | Based on Synergistic Theory and the coupling rule of urbanization & ecological envi-ronment,the coupling degree model (CDM) of urbanization & ecological environment has been put forward,which is divided into coupling degree function and coupling coordination degree fun-ction.The temporal & spatial distribution of the coupling degrees and the coupling coordinationdegrees in China has been analyzed with CDM.The results show that:firstly,the coupling coordination degrees of urbanization & ecological environment are lower and the time sequence of their coupling degrees is basically at resisting stage from 1985 to 2002.Secondly,there obviously exists regional disparity of the coupling degrees and coupling coordination degrees,i.e., the coupling degrees in the eastern regions are higher than those in the middle & western regions;meanwhile,there exists spatial corresponding relationship between the coupling coordination degrees and the levels of economic development,which the coupling coordination degrees are higher in the provinces (regions) where the levels of economic development are higher,otherwise,the coordination degrees are lower.Thirdly,the spatial distribution of coupling degrees and coupling coordination degrees is inconsistent because of differences in economic development,historical evolution,natural environment and policies.Hence,people should adjust its relationship to avoid adverse effect of urbanization development on resources & environment. |
| Keywords: | regional economics coupling degree urbanization ecological environment temporal & spatial analysis |
