摘要
区域土地利用与生态环境之间存在复杂的、非线性、动态耦合关系,这种耦合关系可以看作是二者以土地自然生态系统为公共界面耦合而成的具有鲜明耗散结构特征的复合系统,其内部存在明显的熵值平衡机制,演化轨迹也呈V型。在对二者耦合关系实质进行系统把握的基础上,归纳了二者关系存在四大基本特征,并运用灰色关联分析与系统动力学两种方法为二者关系的研究设计了两种思路,最后就区域土地利用与生态环境耦合关系的调控方向进行探讨。
There is a complicated no-linear relation of dynamic coupling between regional land use and eco-environ- ment by the common interface of land ecology system, which can be regarded as a composite system with vivid dis- sipation structure characteristics. The composite system has a balance mechanism of entropy, and evolves in logistic curve. Based on systemic understanding of the coupling/elation, the paper induces four base features and designs two kinds of thoughts by applying grey correlation analysis and system dynamics. At last, the paper makes a discussion on the regulation orientation of the coupling relation between regional land use and eco-environment
