The flora, distribution area, vegetation structure, annual net primary production, and nutrient uptake of the vascular hydrophytes, hygrophytes and mesophytes were investigated in the wetlands of the Asan-Lake, Chungchongnam-do and Kyonggi-do, Korea from March to October in 1997 to reveal the correlation between the plant community and the lake environment. The flora was composed of 38 families, 89 genera, 106 species, 14 varieties or total 120 kinds of the vascular plants. The life from of the hydrophytes were classified as 14 kinds of emergent plants, 5 kinds of submerged plants, and 4 kinds of free-floating plants, respectively. The number of species was various to 4 ¡­85 kinds in each site. The dominant species was Zizania latifolia, and the importance values of Zizania latifolia, Typha orientalis, Phragmites communis, and Spirodela polyrhiza were 39.58, 14.90, 13.97, and 7.64, respectively. The distribution area of the emergent hydrophytes, hygrophytes, and mesophytes was 49.3 §µ (90.5%), and free-floating plants was 5.2 §µ (9.5%), whereas the floating-leaved and submersed plants were rare. Annual net production of the emergent hydrophytes, hygrophytes, and mesophytes was 547.9 ton D.W./yr (98%), and those of the free-floating plants was 10.5 ton D.W./yr (2%), and 558.4 ton D.W./yr in the whole lake ecosystem. The total uptake of nitrogen and phosphorus by the vascular plants was 7,099 and 1,891 §¸/yr in the whole lake ecosystem.
