摘要
文章根据已有的地质灾害资料，对诸暨市地质灾害发生与分布特征进行了较系统的总结。玄武岩和变质岩分布区地质灾害最为易发，其次是细碎屑岩，地质构造对地质灾害的发生有着很大的控制作用，滑坡主要发生在中等坡（15°～30°），崩塌主要发生在陡坡与急坡（〉30°）。根据地质环境条件，将诸暨市地质灾害区域分为2个中易发区、5个低易发区。
On the basis of the existing geo-hazard data of Zhuji city, Zhejiang Province, the occurrence and distribution characteristics of geo-hazards are systematically summarized.In the areas where basalt and metamorphic rocks outcrop, geological disasters are mostly prone, secondary followed by the area where fine clastic rocks distributed. The geological structures have a great control effect for the geo-hazards. Landslide occurs mainly in middle slope with a range of 15° to 30 °, the collapse occurs mainly in steep and sharp slope with slopeanlge more than 30°. According to the geological environment conditions, two medium-degree prone geological disaster districts and five low-degree prone geological disaster districts in the whole Zhuji city area are outlined.
