| This investigation was carried out to reveal the removal rates of Ca, Mg and Na among the constituents of the litters in Phragmites communis Miscanthus sacchariflorus, Typha augustata and Scirpus tabernaemontani ecosystems in the lake Paldangho. The removal constants of Ca, Mg and Na were determined by the mathematical model and the time required to decay to any percentage of each constituent was calculated by using this model. The results obtained in this study can he abstracted as follows; The removal constants of Ca, Mg and Na of the litters were 0.91, 0.86 and 0.71 in Phragmites communis, 0.64, 0.62, and 0.50 in Miscanthus sacchariflorus, 0.66, 0.28, and 0.56 in Typha angustata and 0.40, 0.55 and 0.63 in Scirpus tabernaemontani, respectively. These values of each constituent in Phragmites communis are the highest among the compared species and in each species, Ca among the studied constituent is higher than the others. The half times of Ca, Mg and Na required for the removal or accumulation of the litters on the grassland floor were 0.76, 0.80 and 0.98 years in Phragmites communis, 1.08, 1.12 and 1.39 years in Miscanthus sacehariflorus 1.05, 2.47 and 1.24 years in Typha angustata and 1.73, 1.26 and 1.10 years in Scirpus tabernaemontani, respectively. Key words: Removal constant, Phragmites communis, Miscanthus scchariflorus, Typha angu-stata, Scirpus tabernaemontani Paldangho. Ca, Mg. Na. |
