天水市城市化与生态环境交互耦合关系研究

A Study on the Coupling Interaction Between Urbanization and Eco-environment of Tianshui

应用刘耀彬等学者提出的城市化与生态环境耦合关系模型,结合天水市实际情况,遴选出天水市城市化与生态环境交互耦合评价指标体系,根据耦合关系模型中涉及的一系列函数,对天水市2001—2010年城市化与生态环境交互耦合度进行分析。结果表明:11年间,天水市城市化与生态环境耦合程度较低,基本处在拮抗阶段,城市化处于快速发展时期,需大量的资源为保障,因此生态承载能力下降,不能够完全吸收和消化城市化过程带来的影响。

In Ught of Liu Yao-bin's theory on the coupling interaction between urbanization and eco-environment and with consideration to the actual situation of Tianshui,an evaluation index system for the assessment of the coupling interaction between urbanization and eco-environment of Tianshui is selected;and by means of a series of functions involved in the index system,the coupling degree between urbanization and eco-environment of Tianshui in 2001-2010is tested.The result shows that in these 11 years the coupling degree between urbanization and eco-environment of Tianshui was low,still in the antagonistic phase.The reason might be that in the process of rapid urbanization,huge amount of resources were in demand,which caused many problems and resulted in the decline of ecological carrying capacity.
