摘要
提出了城市地貌系统的定义和空间范围.认为,该系统具有开放性、有序性、连续性和整体性等特点.详细论述了城市地貌系统各子系统及诸组成要素的地位和作用,以及相互间的网络结构关系.认为,环境功能,经济功能和景观美学功能是该系统的基本功能.最后分析了城市地貌系统能量流、物质流、信息流与结构、功能的关系.
This paper gives out the definition and boundary ranges of unban geom-prphological system which is of the characters of integrality, continuity, orderliness and openness. The positions and roles of branchs, components, and their net structurel correlation in the system are analysed in detail. The author considers that environmental, economical, and landscape aesthetical functions are the most main function of urban geomorphological system. In the end. the relationships between energy fluxes and material fluxes and the structures and functions of the system are discussed.
