摘要
地质灾害的发生和发展是地质环境因素和人类工程经济活动共同作用的结果,其易发性主要受自然因素和人为因素的共同影响。以山东省苍山县地质灾害易发区划分为例,探讨性地采用了地质灾害综合危险性指数法,定量划分了苍山县地质灾害易发区,结果符合当地地质灾害发育的实际情况,为苍山县地质灾害的预防和治理工作提供了科学依据。
Happening and developement of Geological hazards are the result of geological enviroment elements human engineering activities. Regarding easy - happening areas of geological hazards in Cangshan county as an example, by using synthetic hazards index method, geological hazards easy -happening areas can be classifed quanta- tively, and the result fits the facutal condition of geological hazards. It will provide scientific basis for prevention and management of geological hazards.
