 note = {To scrutinize the microbial ecosystem and processing of water quality improvement under the artificial floating island, water quality parameteres, bacterial numbers and extracellular enzyme activities were measured biweekly flom 3, November 2001 to 20,April 2002 in Lake Paldang, Korea. Most of the mean encironmental parameters were not different from artificially floating island (AFI) site and control site. But,zooplankton numbers were about 100 times higher at AFI site than those of control site, even though the chlorophyll α concentrations were not so different. During winter, the rations of respiratory active bacteria to total bacterial number were two fold higher and enzyme activities of β-glucosidase and phosphatase were extremely higher at AFI site than those of contrl site. With these high densities of zooplankton, active bacteria and high rates of degradation under the AFI, the organic materials are eliminated at inside of lake with newly created ecosystem., Article, 信州大学山地水環境教育研究センター研究報告 2: 5-9(2004)},
