我国海洋地质环境研究始于20世纪50年代，80、90年代发展迅速。灾害地质引领海洋环境地质，全球变化研究也卓有成效。全球变化、区域海洋环境地质调查、沿岸的城市地质、滨海地下水环境、海洋灾害地质、海底不稳定性、湿地、人类活动对海洋地质环境的影响等是我国未来海洋环境地质研究的主要内容。中国海岸带地质环境具有构造活动强烈、入海泥沙量大、涌浪频繁、人为环境特征突出等特点。海岸带基本环境问题表现为地质资源利用、人工工程环境、流域环境变化和海平面上升对海岸带环境的影响。黄河三角洲、长江三角洲和珠江三角洲既有共同的特点，又存在着独特的环境地质问题。海底不稳定性和危险地质因素是近海环境地质研究的主要内容。中国近海海域存在构造、斜坡、海底和构造不稳定性以及约40种危险因素。根据地质环境特征，中国近海可划分为17个环境地质区。
Researches of marine geological environment in China began in 1950s, and developed rapidly in 1980s and 1990s. Hazardous geology leads marine environmental geology, and global change study is also fruitful. Global changes, regional marine environmental geological survey, littoral urban geology, coastal groundwater environment, marine hazardous geology, seafloor unstability, wetland, and human influence on marine geologic environment are the main contents of study of future marine environmental geology in China. Coastal geologic environment of China is characterized by strong tectonic activities, huge silt discharge into sea, frequent surges, and prominent artificial environmental features. Basic coastal environmental problems are represented by geologic resource utilization, artificial engineering environment, drainage-area environment changes, and influences of sea-level rise on the coastal environment. The Yellow River, Yangtze River and Pearl River deltas have some common features and also some particular environmental geological problems. Seafloor unstability and hazardous geologic factors are the main concern of offshore environmental geological study. China offshore areas have tectonic, slope, bottom and structural unstability and about 40 kinds of hazardous factors. According to geological environmental characteristics, offshore China can be divided into 17 environmental geologic areas.
