人居环境系统生态流作用机制研究

A Study on the Action Mechanism of Ecological Flows in Human Settlements System

人居环境各子系统之间或它们与系统外部环境之间,不断地进行物质、能量和信息的交换,并且通过生态流(Flow)的集聚与扩散形式联接起来,以此实现人居环境各种功能的正常发挥。将生态流的作用机制概括为人口迁移、物质循环、能量流动(消耗)、信息传递和货币增殖,并构建人居环境系统生态流作用机制模型,以此加深对生态流的作用机制的认识,有助于人居环境的优化调控和可持续发展。

Constant exchanges of substances, energy, and information can be found within the sub - systems of human settlements and between the outside environments, which are connected with centralization and diffusions of the ecological flows so as to exert the functions of human settlements. The article classifies the action mechanism into five categories, i.e. migration, substance recycle, energy consumption, information transfer, and currency multiplication, based on which the model of action mechanism is established to promote the understanding of the action mechanism of ecological flows, and to take measurers to optimize human settlement and attain the goal of sustainable development.
