【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]:In order to better integrate with ecological environment and disaster geology, the second generation of national regional geological records compilation project stipulates that the Quaternary geological and geomorphological map is one of the necessary maps. The contents of the maps include the age of Quaternary geological bodies, genetic types, combination types of lithology and geomorphologic forms, active faults and transgression, and so on. At the same time, the typical sections of Quaternary geology and geomorphology and important landform scenic spots are attached. The geographic background of the map is the first time using the digital elevation model (DEM) data grayscale map as the background / 2) Quaternary geological content and geomorphology form type are the same as a map / 3) Quaternary geological body's face color is used as the origin type color. The geomorphologic part is divided into different types of genetic forms and microgeomorphological attractions. In a word, the map has the sense of three-dimensional, the terrain height difference is obvious, the layer is clear, the color is bright, is a brand-new map, may provide the disaster prevention and the geological tourism reference application.
