THE DEVELOPING PATTERN OF LANDSLIDE GEOLOGY FATALITY IN ZHEJIANG PROVIENCE

The Landslide Geology Fatality has posed serious disadvantages on the safe and development of local socity in Zhejiang province. This article analyses and studys the regularities of distribution and developing pattern of the Landslide Geology Fatality in Zhejiang province based on studying the developing condition and anatomizing the typical types of Landslide Geology Fatality. The results are that the landslide is main geology fatality in Zhejiang province, it has the characteristics of group-development and small size and soil-landslide first and rock-landslide second. The soil-landslide mainly locates at volcaniclastic rock zone in northern and east-northern Zhejiang province; the rock-landslide mainly locates at the sedimentary rock zone in west-northern Zhejiang province. Man-made action and heavy rainfall in flood season are the prime reasons of landslide in Zhejiang province. The heavy rainfall phase is the most likely period of landslide development. This resultes is going to provide the enacting reasonable and effectual countermeasure for calamity with the important environgeology decision-making gists in Zhejiang province.
