    一幅新的第四纪地质及地貌图的编制——以宁夏与山东为例

    The compilation of a new Quaternary geology and geomorphology map with special reference to Ningxia and Shandong

    • 摘要: 为了更好地与生态环境及灾害地质紧密结合,第二代全国区域地质志编制项目规定第四纪地质及地貌图为必编图件之一。图件内容包括第四纪地质体的时代、成因类型、岩性和地貌成因形态组合类型、活动断裂及海侵范围等重要地质内容,同时,附第四纪地质-地貌典型剖面和重要的地貌景点。图件特点:(1)图件的地理底图是首次用数字高程模型(DEM)数据灰度图作背景;(2)第四纪地质内容与地貌成因形态类型同编为一幅图;(3)第四纪地质体的面色用成因类型色表示;(4)地貌部分划分了不同级别成因形态类型和有特色的微地貌景点。总之,图面有立体感,地形高差明显,层次分明,色彩鲜艳,是一幅崭新的图件,可供防灾治理和地质旅游参考应用。

       

      Abstract: Quaternary geology and geomorphology map is one of the series of maps in the second edition of the National Regional Geology Annals, with special attention paid to the close integration with ecological environment and geological disasters. The map includes such important geological contents as Quaternary geological epoch, genetic type, combination type of lithology and geomorphology genesis, active faults and transgression range with the attachment of the typical profiles of Quaternary geologygeomorphology and important landscape attractions. The map has the following characteristics: (1) Digital elevation model (DEM) grayscale image is for the first time used as background for the geographic base map. (2) Quaternary geology features and geomorphologic genetic types are compiled on the same map. (3) The colors of Quaternary geological bodies are indicated by the colors of genetic types. (4) Geomorphologic part is divided into different levels of morphological types and geneses of distinctive micro-topography attractions. In short, the map is a brand new one with three-dimensional drawing, obvious terrain elevation, fine arrangement, bright color, and availability for disaster prevention and control and geological tourism applications.
