| 摘 要： | 在基岩裸露区进行地层解译是比较方便的,但在黄土高原区,尤其是当其还受到林木覆盖时,地层的解译就有一定的难度,问题在于所有基岩的直接解译标志都会被掩盖或受到干扰。在这种情况下,建立间接解译标志就显得十分重要。这些标志包括河道的宽窄变化,曲流强度,色彩差异以及纹形图案等。它们是由岩石成分结构所决定的物理性质、化学组成以及由此派生的波谱特征的外在表现,因而其解译结果是可靠的。

| Abstract: | It is more difficult to interprete the stratigraphy in loessial plateau regions, particularly in woodland places, than in the well-exposed area, because the direct interpretable marks are all obstructed or disturbed by loess and woods. As a result, it is very important to establish the criteria of the indirect stratigrphic interpretation. These criteria include variations of valley width, meandriform, color differences, and schlieren patterns.These features are external expression of the physical and spectrum characteristics of rocks, and in fact they are related to the rock's compositions and texture. Therefore, the interpretation of above criteria is considered reliable. |
