北京市房山区突发地质灾害空间分布规律研究

Study on the Spatial Distribution of Sudden Geological in Fangshan District of Beijing

随着气候条件及人类工程活动的变化,尤其是2012年7·21后,房山区突发地质灾害的发育特征产生了新的变化。为了掌握新时期区域地质灾害空间分布规律,服务于防灾减灾工作,本文借助全区突发地质灾害新一轮的详细调查数据,对全区的突发地质灾害空间分布规律进行了再研究。研究表明,构造形成的地形地貌仍是形成本区突发地质灾害的基础条件,而岩性及人类工程活动对地质灾害的形成具有强化及导向作用。

As the change of climate condition and human engineering activities, especially after the 7·21 rainstorm in 2012 the characteristics of geological calamity in Fangshan District appears new changes. In order to grasp the new spatial distribution of regional geological calamity and serve for the work of calamity prevention and mitigation, In this paper, with the help of the latest survey data of sudden geological calamity in the region, the spatial distribution of sudden geological calamity was studied again The study results show that the topography and geomorphology is the basic condition to develop the sudden geological calamities in this area, and the lithology and the human engineering activities play a guiding role in the development of geological calamity.
