徐州市生态环境-社会经济系统耦合态势分析

城市发展过程中生态环境问题已成为制约城市可持续发展的主要瓶颈,如何实现城市生态环境与社会经济协调可持续发展,已引起全社会的普遍关注。以徐州市为例,基于耦合理论,运用系统演化思想,建立徐州市生态环境—社会经济动态耦度模型,对徐州市1978—2005年28a间生态环境—社会经济耦合态势进行了分析,结果显示:徐州市生态环境—社会经济系统的耦合度分布在-90°～90°之间,生态环境—社会经济系统经历了协调化发展、生态环境恶化与修复重建,再到社会经济与生态环境均衡发展的过程。最后,通过对徐州市生态环境变迁与社会经济发展的研究,总结出几点经验教训,为确切掌握近年来徐州市生态环境和社会经济的状况、科学地认识区域生态环境系统与社会经济系统的演变规律,并为制定科学可行的城市规划与发展方案提供决策支持。
