摘要
本文根据10年的野外调查和定位研究结果,对东北地区水生植物地理学进行了初步研究。文中的东北地区是指东北自然地理区,将内蒙东北部归入东北地区更能体现出该区域的自然地理特点,而利于讨论东北水生植物的分布规律。文中将东北水生植物的水平分布规律分为经向与纬向地带性,并以长白山等为例阐述了水生植物的垂直分布规律。文中首次对水生植物的跨带分布进行了探讨,并试提出隔带分布概念。同时,根据地史演变和孓遗现象等对东北水生植物的分布区类型和隔带分布现象进行了探讨。
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.
