Abstract
The effect of different turnover time of water on the decomposition of emergent macrophyte litter (Zizania latifoliaGriseb.) was investigated using a microcosm experiment. Microcosm treatment represented different turnover time ofwater; 1, 2, 4 and 8 weeks. The litterbags from each treatment were retrieved every 2 weeks until the 8th week and thewater simultaneously sampled with the litterbag. The dry weight and the content of major cations in the litter, and thecontent of available N, P, and major cations in the water were analyzed. Dry weight loss after 8 weeks indicated the lowerdecay rates under the condition of short turnover time of water. Major cations from the litter and the water showed thatthe leached amounts of K and Mg from the litter were highest in the 2nd week and dramatically decreased from the 4thweek. The dynamics of available nitrogen and phosphorus in the water showed that as the water turnover time was gettinglonger, the amounts of available nitrogen and phosphorus remained higher. These results suggest that wetlands withlonger turnover time of water could maintain the increased nitrogen and phosphorus and no outflow of the nutrientscould cause eutrophication problem.
