摘要:
通过遥感、水文和水化学、综合物探、地质取样、钻探以及静力触探等多种调查手段与方法,首次在我国重点经济区——珠江三角洲的近岸开展了1∶10万比例尺海洋地质环境与地质灾害综合调查,对调查区水域的海水化学要素、环境质量、水动力、地形地貌、沉积物、浅地层结构、潜在地质灾害以及海底工程地质条件进行了综合分析与研究,对海洋地质环境进行了综合评价与预警,并对该区海洋开发和工程建设提出了建议.

Abstract:
A 1∶100000 coastal marine geological environment and geological hazard investigation was carried out for the first time in the Pearl River Delta,one of the most important economic zone in China,basing on integrated method of remote sensing,hydrology and hydrochemistry,comprehensive geophysical survey,geological sampling,geological drilling,and static sounding. The chemical parameter of seawater,marine environmental quality,hydrodynamics,topography and geomorphology,sediments,shallow stratigraphic structure,potential geological hazards and submarine engineering geological conditions were analyzed,and the marine geological environment was assessed and forecasted. Finally,reasonable suggestion about coastal marine development and engineering construction were put forward.
