Abstract: Basod on the results obtained through ten years fixed positional studies, the geography of aquatic plants from Northeast China was discussed in the paper.The natural region of Northeast China should include Northeast Inner Mongolica which can further show the natural geographical caracteristics of the region. The horizontal vegetation zone of aquatic plants was divided into the dispersal patterns of either longitude or latitude. The vertical vegetation zone was clarified with the examples from Changbaishan Mountains etc. The extensing across zones and partitive zones of the distribution of aquatic plants were explored and the areal-types of aquatic plants were also expounded.

Key words: Northeast China, Aquatic plants, Areal-types, Geographical distribution, Partitive zones
