摘要:

在构建土地生态系统服务和城市化2个子系统指标体系的基础上,采用价值系数法核算福州市各种土地生态服务的价值,并提出采用匀滑技术来弥补城市化系统个别指标数据片断的缺失,最后,利用协同学思想构建2个子系统之间的耦合度模型,探讨了不同序参量上、下限的选择对系统耦合关系的影响,并对福州市的土地生态系统服务与城市化之间的耦合关系进行了测定和互动关系分析。研究结果表明:① 序参量上、下限值的选择对土地生态系统服务与城市化系统的耦合度具有一定的影响,但对区域时间序列总体变化趋势的影响不大。② 福州市土地生态系统服务与城市化的交互耦合在2000年处于磨合阶段,而后进入高水平的耦合阶段,且两者的耦合协调度值处于0.36~0.82之间,除了2000年处于低度协调,2000年以后均处于中度协调及以上水平。③ 动态耦合模型与容量耦合函数模型两者计算得到的耦合度变化规律高度一致。

Abstract:

Based on the coupling and coordinative characteristics of environment system and urbanization system in Fuzhou, taking land ecosystem services and urbanization as two composite systems respectively, through the quantitative integration measure, this article aims at probing into the coupling interaction and coordinating relationship of environment and urbanization system of Fuzhou City, which locates in the Economic Zone on the Western Coast of the Taiwan Straits, China. Firstly, the land ecosystem services are evaluated by the method of value coefficient, and the lack of data fragments of the urbanization indicators are complemented by the smoothing method. Then, on the basis of Synergistic Theory, the theoretical models of land ecosystem services and urbanization were constructed to measure the coupling and coordinative degrees, and to analyze the effects of different upper and lower limits of the order parameters on the coupling and coordinative degrees and the interactive relationship between the two composite system from 2000 to 2009 in Fuzhou City. The results show that: firstly, the coupling and coordinative degrees are greatly affected by the different upper and lower limits of the order parameters, while the time sequence trends of the coupling and coordinative degrees in different limits are the same. Secondly, the coupling and coordinative degrees of land ecosystem services and urbanization are at run-in stage in 2000, then they enter into a high level coupling stage after 2000. Thirdly, the coupling degree values from the dynamic coupling model are highly consistent with those from the capacity coupling model. The studies provide the theory basis and the practical guidance for realizing environmental coordinated development. To maintain the present situation of higher coupling and coordination degrees of environment and urbanization system in Fuzhou, the government, the enterprises, together with the residents, should control their own behavior, including policy formulation and effective implementation, application of advanced environmental technology, the guide of market mechanism, and the enhancing of public environmental awareness.

Key words: ecosystem services, urbanization, coupling degree, Fuzhou City
