城市化与生态环境的耦合度模型及其应用

在城市与生态环境耦合规律的基础上，利用协同论的观点构筑了它们之间交互作用的耦合度模型。模型包括两部分即耦合度计算模型和耦合度预测模型。耦合度计算模型由功效函数、耦合度函数和城市化-生态环境耦合评价指标体系构成其中指标体系的选择是耦合度计算正确与否的关键。耦合度预测模型采用人工神经BP反馈网络。最后，以徐州市为研究对象应用此模型研究了该城市化与生态环境耦合的现状和发展趋势，为协调好它的城市化与环境建设提供了量化的决策依据。

COUPLING DEGREE MODEL OF URBANIZATION AND ECOLOGICAL ENVIRONMENT AND ITS APPLICATION

Based on Synergistic Theory and the coupling rule between urbanization and ecological environment, the Coupling Degree Model of urbanization and ecological environment has been put forward, which is composed of two parts, i.e. Coupling Degree Model and Forecasting Model. The Coupling Degree Model includes Efficacy Function, Coupling Degree Function and its index system, in which the index system is crucial and determines its available application. Forecasting Model of Coupling Degree adopts BP network according to artificial network characteristics. At last, the coupling degree and forecasting coupling degree of Xuzhou city have been investigated and to some quantitive suggestions developed.
