A STUDY ON COMMUNITIES OF AQUATIC VASCULAR PLANTS IN BEIJING

15 types of aquatic vescular plant communities are reported. They are Co. Phragmites australis , Co. Typha angustifolia , Co. Nasturtium officinale , Co. Veronica undulata , Co. Polygonum lapathifolium , Co. Lemna minor , Co. Spirodela polyrrhiza , Co. Hydrocharis dubia , Co. Salvinia natans , Co. Nymphoides peltatum , Co. Potamogeton distinctus , Co. Potamogeton crispus , Co. Batrachium bungei , Co. Potamogeton malainus+Potamogeton perfoliatus and Co. Myriophyllum spicatum . These communities belong to 4 vegetation types: emergent aquatic plant community, freely floating aquatic plant community, floating leaved aquatic plant community and submergent aquatic plant community. Cosmopolitan species and temperate species are main distribution types in these communities. Besides, ecological value, human interference, conservation and utilization of the communities are also discussed.
