水文地质普查测绘比例尺的大小常按要测绘地区的地质、地貌、水文地质条件的简繁程度及其在国民经济上的意义而定。虽然普查测绘所用之比例尺不同,但其所要解决的主要问题是一致的,如:地区的地层、地貌及水文地质条件的变化,以及规律性和其互相间的因果关系,最终提出其在国民经济上的意义。因而,衡量该区水文地质成果是否合格,应视其能否满足编制该区国民经济远景规划的需要。为使水文地质普查测绘工作能更进一步地多快好省的发展,现将个人在测绘工作中的点滴体会提供于下:
The scale of hydrogeological census surveying and mapping often depends on the geological, geomorphological and hydrogeological conditions of the surveying and mapping area and the significance of their significance in the national economy. Although the scales used by the census surveys are different, the main problems to be solved are the same, such as the change of stratigraphy, geomorphology and hydrogeological conditions in the area, as well as the regularity and the mutual causal relationship between them, and finally put forward their proposals in the national economy On the meaning. Therefore, if the hydro-geological achievements in this area are qualified, it should be considered whether it can meet the need of compiling the plan for national economy in the area. In order to enable the development of hydrogeological census surveying and mapping work to be more rapid and economical, the present personal experience in surveying and mapping is provided below:
