大城市边缘区人居环境系统结构与功能研究

The Structure and Function of Human Settlements in Metropolis Fringe

从系统角度分析大城市边缘区人居环境的结构与功能.在垂直方向上,将人居环境系统划分为7个层次,即家居、建筑、社区(邻里)、城市、区域、国家、全球人居环境,不同的尺度构成了人居环境的尺度链,而且随着空间尺度的增加,人居环境的过程速率逐步放慢,空间分辨率不断降低,事件频率也逐渐变低.大城市边缘区人居环境系统是一个社会——经济——自然复合生态系统,除了具有生活、生产、消费、还原和调节5大基本功能外,还具生境功能、滤网功能、通道功能、源功能和汇功能等特殊功能,并指出系统功能发挥的必要条件.

Human settlements system is a complex gigantic open system whose structure and function are dialectic and unitive. In the level aspect, the system can be separated into five sub-systems, i.e. nature, people, community, inhabitancy, and support sub-systems. In the uprightness aspect, the system comprises seven distinctions, i.e. furnishings, architecture, community, city, region, country, world scales which constitutes human settlements scale chain. It puts forward that human settlements system in metropolis fringe is a special society-economy-nature complex system with the common functions of living, producing, consuming, revivification and modulation, as well as the special functions of inhabiting, filtrating, channels, sources and collection, and then the necessary conditions of exert ing functions are proposed.
