| 摘 要： | 对羊草草地枯枝落叶和分解者之间的能量流动过程分析表明，每年因植物枯死输入到枯枝落叶的能量为3769.42kJ／m2／a；储存在枯枝落叶中的能量为：3424.10kJ／m2；每年被分解者所消耗的能量为1141.67kJ／m2／a，其中71.87%的能量用于呼吸作用。目前在羊草草地上，枯枝落叶和分解者之间的能量流动输入大于输出，能量处于积累阶段。当达到稳定状态时，储存在枯枝落叶中的能量为11305.61kJ／m2，分解者中的能量为1475.20kJ／m2。

| Abstract: | The results of the energy flow analysis on litter and decomposing organisms showed that energy to be input into litter is about 3769.42kJ/m~2/a owing to pl- ants death;the litter energy mass is about 3424.10kJ/m~2;the energy consumed by decomposers is about 1141.67kJ/m~2/a,71.87% of which is used for respi- ration of decomposers.At present,inputing energy is more than outputing ene- rgy in the process of energy flow between litter and decomposers,energy is on accumulating stage in Aneuroplepidium chinese grassland.Energy mass stored in litter will be 11305.61kJ/m~2 and in decomposers will be 1475.20kJ/m~2 at stea- dy state. |
