地貌过程对山区城镇规划和建设的基本影响

Influences on Layout and Construction of Urbans and Towns in Mountainous Area

基于多年的实地工作，就地貌过程对山区城镇规划和建设的基本影响进行了探讨。研究认为，地貌过程，尤其是以滑坡、泥石流等为主的灾害地貌过程对山区城镇规划和建设具有非常明显的影响和作用，不合理的人为活动（边坡开挖切割、加载等）通过加速灾害地貌过程的发育去影响山区城镇的规划和建设，而新构造应力场则可在宏观上控制灾害地貌过程的发育和分布。在山区城镇规划和建设过程中加强灾害地貌过程的研究，具有重要的实用价值。

On the basis of investigations in field for years,some basic influences on layout and constructions of urbans and towns in mountainous area from geomorphological processes are studied.The results prove that geomorphological processes,especially catastrophic geomorphological processees (a mud- rock flow or a landslide) do important effect on the layout and construction of the urbans and towns.The paper also studies some effects on the urbans and towns from irreasonable human activities.
