The data truly reflects the macro spatial pattern of the region, with forests as the ecological core, grasslands and cultivated land distributed east-west, and wetland systems interwoven vertically and horizontally. The large and small Xing'an Mountains form a continuous forest body; The western Hulunbuir High Plain is dominated by vast grasslands; Farmland is fragmented and distributed on the southern edge and river valley plains. Special records were made on the segmentation of natural cover by the engineering corridor composed of linear engineering projects such as the China Russia crude oil pipeline CRCOPs I&II, G111/G301/G331 highways, and the Nenlin/Binzhou railways. This data provides key foundational cover parameters for analyzing the hydrothermal stability of engineering corridors and the environmental effects of permafrost degradation over the years.
