中国1:400万地貌图(构造地貌)

地貌:表起伏的形态，如陆地上的山地、平原、河谷、沙丘，海底的大陆架、大陆坡、深海平原、海底山脉等。根据地表形态规模的大小，有大地貌、中地貌、小地貌和微地貌之分。。本数据集为构造地貌图，由陈志明先生主编完成，将陆地和海洋地貌分为四级:A级为大陆地形形态分类、B级为大陆构造地貌分类、C级为大陆堆积物及堆积地貌、D级为地貌形态符号、E级为海底地貌分类。

Landform refers to undulating surface forms, including mountains, plains, valleys, and sand dunes on terrestrial land, as well as continental shelves, continental slopes, abyssal plains, and seamounts on the seabed, among others. Based on the scale of surface landform features, landforms can be categorized into macro-landforms, meso-landforms, small landforms, and micro-landforms. This dataset is a tectonic geomorphology map compiled by chief editor Mr. Chen Zhiming, which divides terrestrial and marine landforms into four hierarchical levels labeled A to E: Level A corresponds to the classification of continental topographic forms, Level B to the classification of continental tectonic landforms, Level C to the classification of continental sediments and depositional landforms, Level D to the symbols of geomorphic forms, and Level E to the classification of seabed landforms.
