山东省主要地质灾害有矿山地质灾害、海（咸）水入侵、岩溶塌陷、水土流失、崩塌、滑坡、泥石流及地面沉降、地裂缝等，其发育和分布严格受地质构造、水文地质条件的制约，同时也受气象、人类活动等因素的影响。这些灾害危害很大，往往造成巨大的经济损失，并伴有人员伤亡。文中对其分布规律、危害程度、致害因素及区域活动性等做了分析，并提出了防治对策及防灾减灾建议。 Major geological disasters in Shandong Province include mine geological disasters, seawater intrusion, karst collapse, soil erosion, landslide, landslide, debris flow and land subsidence, ground fissures, etc., whose development and distribution are strictly controlled by geological structures and hydrogeological conditions , But also by the weather, human activities and other factors. These disasters are so damaging that they often result in huge economic losses and casualties. The paper analyzes the distribution, the degree of harm, the factors that caused the damage and the activity of the region. It puts forward the countermeasures of prevention and mitigation and the proposals of disaster prevention and mitigation.
