초록

인공연못녹화를위해국내 11개연못에서수집한84종의자생수생식물을 6m×3m×1.5m 크기의인공연못에식재하여 12개월간생장시킨후관상가치가뛰어나고, 체내 N, P함량이많아수질정화용으로이용가능성이높을것으로예상되는종을선발하였다. 체내N함량이높은종은마름, 어리연꽃, 수련, 벗풀, 물수세미였으며, P함량은물옥잠, 벗풀, 소귀나물에서높았다. 생태연못조성에이용할수있는종으로 4월에 5 종, 5월 19종, 6월 23종, 7월 32종, 8월 31종, 9월28종, 10월 26종을각
선발하였다. 연못의 pH는22개월동안 6.8~7.6수준이유지되었으며, EC는식물생장기인봄과여름에는비교적낮았으나가을로갈수록높았다. 인공조성연못의 1년경과후식생은당초 78종(Potamogeton octqandrus, Salvinia natans, Potamogeton malaianus etc.)에서 38종(Scirpus
tarbernaemontani, Scirpus karuizawensis, Scirpus triqueter etc)으로감소되었으며, 종다양성면에서종수는 38종, 총개체수는 1,437개, 종풍부성지수는 11.72,
최대다양성지수는 0.97로나타나인공연못이비교적안정되게유지되었다.

This experiment was conducted to acquire the basic data necessary for the artificial pond green­ing. Eighty four hydrophytes collected from 11 domestic small ponds and a farm were used in this experi­ment. The size of the artificial pond used was 6m×3m×1.5m (length×width×depth). Twelve months after planting, species were selected for their high ornamental values and tissue contents of N and P in each month. Tissue contents of N in Trapha nantan, Nymphoides indica, Nymphaea hybrid, and Murdannia kei-sak were high. Tissue contents of P in Monochoria vaginalis and Murdannia keisak were also high. The pH of artificial pond stabilized at a 6.8~7.6 range from May 2005 to March 2007. The EC was low in summer and high in autumn. From April to October, 5, 19, 23, 32, 31, 28, and 26 species, respectively, were selected for artificial pond greening. One year after planting, vegetation changed from 78 species (Potamogeton octqandrus, Salvinia natans, Potamogeton malaianus, etc.) to 38 species (Scirpus tarbernaemontani, Scir-pus karuizawensis, Scirpus triqueter, etc.). Species diversity in the artificial pond was as follows, indicating it being a stabilized artificial pond; 38 species, 1,437 total number of plants, species richness index of 11.72, and maximum diversity index of 0.97.
