基于熵理论和尖点突变模型的生态城市建设机理分析

Analysis of Ecological City Construction Mechanisms Basing on the Entropy Theory and Cusp Catastrophe Model

从生态经济学视角出发,基于熵理论,应用尖点突变模型,力图从新的视角揭示生态城市建设的作用机理。研究表明：生态城市建设是稳定的,单纯线性增长机制在改善城市的生态状况方面,效果并不会太明显,并容易引起生态城市建设的逆向选择问题;生态城市建设的突变依赖于特定的条件,即存在着微小但却是导致有序的涨落机制;生态城市建设允许多样性,即生态城市建设中存在着多种不确定的非线性机制。

In the high-speed economic development, the city ecological environment is deteriorating. To explore the mature mode of ecological city construction has gradually become the focus of all fields. This paper tries to re- veal the mechanism of ecological city construction from a new perspective, beginning with ecological economics and basing on the entropy theory and cusp catastrophe model. The research shows that the construction of ecologi- cal city is stable. Using pure linear growth mechanism to improve the city ecological situation, the effect would not be too obvious and can lead to adverse selection problems of the ecological city construction. The catastrophe of ecological city construction depends on specific conditions, i.e. there is a small but actually causes fluctuation mecha- nism orderly. The construction of ecology city allows diversity, i.e. there exist many uncertain nonlinear mecha- nisms in the construction of ecological city.
