山东省长山列岛北部海域浅表层海洋灾害地质特征及成因机制分析

Analysis on Geological Characteristics and Genetic Mechanisms of Shallow Surface Oceans in the Northern Sea Area of Changshan Islands in Shandong Province

摘要:

海洋灾害地质作为影响海洋资源开发、海洋工程建设活动的重要因素,越来越受到人们的重视。通过对长山列岛北部海域多波束测量、浅地层剖面测量工作成果资料的解译研究，分析了影响海底浅表层潜在海洋灾害地质的因素，查明了主要灾害类型、埋藏特征和分布范围，编制了灾害地质分布图,分析了灾害地质的形成机制及危害性,研究区灾害类型主要有海底冲刷槽、浅层气、埋藏古河道、断层等。为研究区海洋资源的开发利用，尤其海洋牧场建设等工作提供科学依据。

Abstract:

Marine disaster geology, as an important factor affecting the development of marine resources and marine engineering construction activities, is receiving increasing attention from people. Through the interpretation and research of the results of multi beam measurement and shallow profile measurement in the northern sea area of Changshan Archipelago, factors that affect the potential marine hazard geology in the shallow surface of the seabed have been analyzed, main types of hazards, burial characteristics and distribution range have been identified, hazard geological distribution map has been made, the formation mechanism and harmfulness of hazard geology have been analyzed, and main types of hazards in the study area have been found, including submarine scouring channels, shallow gas, buried ancient river channels and faults. It will provide a scientific basis for the development and utilization of marine resources in the study area, especially for the construction of marine pastures and other work.
