| Abstract: | On Aneurolepidium chinease grassland, the amounts of N, P and Ktransferred from deadplants into the litters are respectively 0.7227, 0.1137 and 0.4974g·m-2·yr-1.After oneyear, the loss rates of them are respectively 59.71, 73.21 and 83.26%.Under imbalancestate, the input of these three elements is larger than their output, being at accumulationstage, while under stable state, their contents in litters are respectively 1.1859, 0.1565 and 0.5963g·m-2. |
