1.1 The main contents of this standard are: groundwater types and water abundance, groundwater quality, controlling water points, characteristic symbols of special areas, boundaries and others, geological and structural elements, geographical elements, legend of cross-section drawings, schematic diagrams of drawing configuration and color codes. 1.2 This standard is applicable to the preparation of comprehensive hydrogeological maps and auxiliary maps at a scale of 1:200000 to 1:500000. The legends and color codes specified in this standard are important components of comprehensive hydrogeological maps and are the basis for the preparation and printing of comprehensive hydrogeological maps. 2 Reference standards

3.1 Principles for the compilation of this legend: Combined with the map capacity of 1:200000~1:500000 comprehensive hydrogeological map, ensure that the map content is complete, the levels are clear, the key points are highlighted, the meaning is accurate, and it is clear and easy to read: While considering the systematic and scientific nature, it also takes into account practicality and versatility; when formulating this standard, the commonly used legends and color codes in the domestic geological and hydrogeological circles were considered, and they were coordinated with similar international standards or schemes as much as possible to facilitate international exchanges; considering the current printing technology and level, it is convenient to compile and print economically. 3.2 The type and water-richness of groundwater are represented by general coloring; the water-richness of the underlying confined freshwater and the top plate burial depth are represented by reticulated symbols. For multi-layer aquifers, a layered compilation method can be adopted. When compiling the layers, the third and fourth aquifers can repeat the representation method of the first and second aquifers. 3.3 The quantitative classification in this standard takes into account the general situation in most areas of my country. For special cases not specified, it can be further subdivided or the design symbols can be supplemented according to the specific situation. 3.4 The diagram of the map configuration of this standard is used for compiling maps of different scales of various international divisions, and can also be used as a reference for the map configuration of self-designed comprehensive hydrogeological maps.
