H、C、(?)(1963)认为:用图例符号表示各种级别及各种时代的构造形态的图叫做构造图。构造图可分为表示构造形态的地质构造图和纯构造图(概要的和区域的构造图)和专题构造图。如果研究者的目的是编制反映构造形成时代及历史的纯构造图,那么他们时常要碰到图例问题。这时就应当解决以下问题:怎样在同一张图上采用各种图例符号表示历史意义,即 H, C, (?) (1963) that: the legend with various symbols and various levels of tectonic patterns of the times called the construction map. Tectonic maps can be divided into geological tectonic maps and pure tectonic maps (synoptic and tectonic maps of regions) and tectonic maps that represent the tectonic patterns. If the purpose of the researcher is to compile purely constructed maps that reflect the age and history of the formation, they often encounter the problem of legend. At this time, the following questions should be solved: How to use the legend symbols in the same figure to indicate historical significance
