Abstract Share this page

Two types of urban corridor,artifitial corridor and natural corridor,is studied.The corridor effect concept is examined in the urban landscape structure.The analysis is undertaken by using a DistanceDecay Function,which is based on idea concerning the concept "corridor benefit".The demarcation line between artificial corridor and natural corridor is the synthetic benefit point from the theory analysis.It is suggested that there are two sunthetic benefit points on the curves of DistanceDecay Functions for the existence of a natural corridor between two artifitial corridors.In particular,it is necessary to avoid a high density of artificial corridors and to improve social and economic benefits in the natural corridors.The spatial growth of 8 corricors is examined in the central area of Beijing.This inner city study attempts to replicate several findings of green area and water system as a framework aroud and through the center of the city combined with the eight directions of natural corridor effects.Ideas of human and natural in perfect harmony is used in the urban ecological landscape planning.The landscape structure of Beijing should change from a multiple form to a star shaped multiple form in order to avoid the massive growth of the builtup area.
