摘要:
成果的有效应用服务是城市地质调查工作的核心驱动力，城市地质数据集作为城市地质调查工作的核心成果，是决定城市地质调查研究成果应用服务有效性的关键。中国地质调查局部署开展丹阳小城镇地质环境综合调查试点，本次共完成遥感解译1 047 km2 (3期数据)，调查点767个，钻探115个，累计钻探进尺8 720 m (其中第四系孔915 m，水文孔2 366 m，工程孔5 439 m)，采集第四纪地质样品2 904组，地下水样品240组，原状土样1 108组，土壤样2 482组，地下水位统测点70 个，抽水试验18组等。查清了丹阳市水文地质、工程地质、地质灾害等分布规律，并围绕丹阳市规划建设对地质工作的实际需求，对各类调查原始数据进行了专项加工，建立了数据集，为丹阳市规划建设提供了良好的支撑服务。文章对数据来源、数据收集方法、处理技术等方面进行了整理和归纳，形成了小城镇地质调查应用服务地质数据集的构建方法，为今后小城镇地质调查和数据集处理及应用提供参考。
Abstract:Effective application of survey results in social service is a core driving force of urban geological survey. As the key result of urban geological survey, the urban geological dataset is critical to the effective application of geological survey results in service. The China Geological Survey (CGS) has deployed a pilot project for comprehensive survey of geological environment in small towns of Danyang. The workload of the comprehensive survey involves the interpretation of remote sensing images covering an area of 1 047 km2 (including data from three phases), 767 survey points, 115 boreholes, accumulated footage of 8 720 m (including 915 m for the Quaternary boreholes, 2 366 m for hydrological boreholes, and 5 439 m for engineering boreholes), 2 904 Quaternary geological samples, 240 groundwater samples, 1 108 undisturbed earth samples, 2 482 groups of soil samples, 70 points for simultaneous measurement of groundwater levels and 18 pumping tests. In this work, the distribution laws of the hydrogeology, engineering geology, and geologic disasters in Danyang City were ascertained. Furthermore, in view of the geological demand in the planning and construction of Danyang City, the original data obtained from various surveys were specially processed and a dataset was developed accordingly, thereby, providing strong support for the planning and construction of Danyang City. In this paper, the method of developing a geological survey dataset of small towns for the purposes of application and social service was established by collating and summarizing data sources, data collection methods and data processing techniques, in order to provide references for a geological survey in other small towns as well as the processing and application of the geological dataset in the future.
