| Abstract: | On Aneurolepidium chinease grassland, the amounts of N, P and K transferred from deadplants into the litters are respectively 0. 7227, 0. 1137 and 0. 49749. 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. 1565and 0. 5963g. m-2. |
