地质编图和其他地学编图一样,它是传输工具,信息积累器,是研究客观实体(或观察实际)的模型,是地学分析研究的手段。积极开展淮河流域地质编图工作,对于加速淮河的治淮,推进四化建设,既是必要的,也是可能的。建国之初,淮河流域曾是全国开展水利水电建设,进行水文、工程地质工作较早的地域之一。卅多年来,随着工业、农业的发展,从山区到平原,从地表到深层,都进行过较为广泛的地质勘探(加上地质、石油、交通、城建等部门的勘探),积累了极其丰富的第一性资料。但是至今却没有一份系统的流域性的地质图件。一方面可能是范围较大,另一方面是勘探目的各不相同,流域机构又没有倡议,因而资料随做随存,束之高阁,缺少综合利用和全面分析。随着治淮事业的推进,规划工作不断向深度发展,要求具有完整的、系统的地质图系,已逐渐提到 Geological mapping, like other geography books, is a transmission tool, accumulator of information, a model for studying objective entities (or observing reality), and is a means of geoscientific analysis. To actively carry out the work of geological mapping of the Huaihe River Basin is both necessary and possible to speed up the Huaihe River’s Huaihe River administration and promote the four modernizations. At the beginning of the founding of New China, the Huaihe River Basin was once one of the regions where hydropower and hydropower construction was started in China and hydrology and engineering geology work earlier.卅 Over the years, with the development of industry and agriculture, more extensive geologic exploration (plus exploration in geology, oil, transportation, urban construction and other departments) has been carried out from the mountains to the plains and from the surface to the deep level, accumulating extremely rich The first data. But so far there is no systematic geological map of the basin. On the one hand, it may be a large area, on the other hand, different exploration purposes and no initiative by the basin authorities. As a result, the data are stored on the shelf and shelved. There is a lack of comprehensive utilization and comprehensive analysis. With the advancement of the Huai River harnessing project, the planning work has continuously progressed to a deeper level, requiring a complete and systematic geological mapping system, which has been gradually mentioned
