In this paper, a new method based on the space syntax is presented to optimize the urban space configuration. Space syntax theory is used to detect systematically whether one urban space configuration is optimal or not from four aspects including traffic space, cognition space, land use space and culture space. After introducing the computational and cognitive aspects of space syntax for the research of urban space, a framework of urban space optimization based on space syntax is proposed, then the integration with GIS and the extension to third dimension are discussed. Finally, a case study for Kanmen town of Zhejiang province of *** is illustrated by using Axwoman tool.

'5.12.汶川地震次生灾害中,有两类山地灾害至今仍对公路运营安全影响很大,其一是高高堆积在坡体之上且规模较大的松散(动)危岩体,其二是与岷江大致正交的泥石流沟泥石流。它们共同的特点是危险物源分布相对位置高、体量大、来势凶猛、冲击破坏性极强,加上它们发生的时间或空间的不确定性,致使常规防治措施无能为力并极易遭到破坏。复式明洞工程则是针对上述灾害专门提出的公路实用性防护工程。经过前期运行,已明显体现出这类工程的优越性,同时也凸显出一些尚需进一步改进的地方。
