摘　　要：本文梳理了影响渤海湾北岸生态文明建设的主要地质问题,结合近年来开展的区调工作分析了平原区1∶5万区域地质调查在解决这些地质问题中所能起的作用。平原区1∶5万区域地质调查能够查明第四纪地层结构,进而确定含水层的分布、时代和性质,为城市建设所需的应急水源地以及合理开采、利用地下水资源提供依据;能够查明区内主要断裂的分布及其活动性,为地壳稳定性评价提供资料支撑,也为重大工程建设规划和减灾防灾提供依据;能够详细调查区域岩相古地理,确定不同沉积相的分布空间,在此基础上查明河、湖和沼泽等湿地的形成演化过程,分析其控制因素,为改善生态环境提供依据。总之,平原区1∶5万区域地质调查能够为区域经济和地方政府在管理决策、环境治理、灾害防治等方面提供基础地质资料。This paper presents the main problems of ecological civilization in northern coast of Bohai Bay, and comes forward the functions of 1∶50 000 regional geological survey in solving these problems. 1∶50 000 regional geological survey can ascertain the age and property of aquifers, and analyze the characteristics of storage space and the channel of underground water, and provide the basis for using the groundwater resources and combating pollution. It also can investigate the main fault location and activity, provide the basis for the crustal stability evaluation and regional engineering geology and surface subsidence. It can investigate the formation and evolution of different wet lands, and analyze its controlling factors, and provide the basis for improving the ecological environment. In a word, it is basis geological information for local government to do well in the managerial decision, environmental governance, disaster prevention and so on.
