摘　　要：根据山东半岛北部区域地质构造特点,结合地质灾害历史记录综合分析认为:山东半岛北部地质灾害以沿海城市易发的海水入侵、海岸侵蚀和汛期发生的崩塌、滑坡、地面塌陷、地裂缝等交发性地质灾害以及地震灾害、矿山灾害为主。其中崩塌、滑坡等灾害频繁但规模较小,多分布于鲁东山区,分布集中.形成条件大致相近,具有周期性变化规律.其诱发因素主要是地震和降雨。人类经济活动如筑路、修建水库和露天采矿等也日趋加剧了地质灾害的发生与发展.并且地质灾害活动有逐年加重之势。本文分析了其发育特点、形成条件及发展趋势.为全面认识灾情状况,制定区域减灾规划及防治措施提供了科学依据。According to regional tectonic features and geological hazards historic records in northern Shandong Peninsula, the general conclusion is that the main geological hazards in northern part of the Shandong Peninsula is sea water invades in coastal cities, coastal erosion and avalanche, landslide, sinking of ground and crack during the flood season, as well as the earthquake and mine hazards. Avalanche and landslide occur frequently but on a small scale. Most of the avalanche and landslide, which are induced by earthquake and rainfall periodically, are centralized distribution and broadly similar form in the mountainous area of east Shandong province. The humanity economic activity, like road building, reservoir constructing and open-air mining and so on, also intensify the occurrence and development of geological hazards, and it is aggravating potentially year by year. The development features, formation conditions and development trend of the geological hazards are analyzed, which can provide a scientific basis for understanding hazards situation, formulating the plans, preventing and controlling measures.
