景观地带设置形式对人员疏散流动效率的影响研究*

为研究景观地带设置形式对周边人员疏散流动效率的影响，在实地调研景观地带设置形式基础上，运用Pathfinder软件设计8种情景模拟，探究不同景观点形状、位置和不同流动路径对人员疏散流动效率的影响。研究结果表明:在单边单向通行路径中，方形景观比圆形景观更有优势，将景观点以周边通道宽度的10%向人流输出方向平移设置，可获得最佳人员疏散流动效率；在双边双向通行路径中，圆形景观比方形景观更有利于形成稳定高效的疏散人流。

Study on influence of landscape zone setting form on personnel evacuation flow efficiency

In order to study the influence of landscape zone setting form on the evacuation flow efficiency of surrounding personnel,based on the field investigation of landscape zone setting form,the Pathfinder software was used to design 8 scenarios,and the influence of different landscape point shapes,locations and different flow paths on personnel evacuation flow efficiency was explored.The results showed that in the unilateral one-way traffic path,the square landscape had more advantages than the circular landscape,and the optimal personnel evacuation flow efficiency could be obtained by setting landscape point as 10% of the width of the surrounding channel with translation to the flow output direction.The circular landscape was more conducive to the formation of stable and efficient evacuation personnel flow than the square landscape in the bilateral two-way traffic path.
