关于山谷型城市的防震

Earthquake prevention of valley-type cities

汶川地震对四川北部的山谷型城市造成了毁灭性的破坏,在应对地震灾害时该区域的城市空间布局表现出很大的局限性,而合理完善的城市空间布局对该类地区居民生命财产的安全以及震后的有效救援是相当重要的。以山谷型城市为例,运用系统论的方法,从宏观、中观、微观三个层面分析目前山谷型城市空间布局存在的不足,进而探讨合理的山谷型城市空间布局模式,以降低地震灾害对该类地区的影响。

The Wenchuan earthquake caused the devastating disaster to the valley city in the northern of Sichuan, the urban space layout showed a lot of limitations dealing with earthquake hazard, and reasonable and perfect layout of urban space for the life safety and rescue after earthquake is very important. the article analyses the current shortage about valley urban space layout from the macro, meso, micro -level by system concept, and then probe a reasonable urban space layout to reduce the impact of the earthquake disaster under the three levels.
