【摘要】 本文研究了埋藏在不同深度的3种典型湿地植物枯落物的热值在一个生长季内的变化特征,并初步探讨了其影响因素。研究表明小叶章和漂筏苔草枯落物热值呈现相同的变化特征:0-10cm、10-20cm、20-30cm三个层次两种植物的枯落物热值随着分解的进行,逐渐下降。30-40cm层次热值呈现波状起伏。而毛果苔草枯落物热值的变化起伏大,规律特征不明显。更多还原

【Abstract】 This text has studied the calorific values of litters in 3 kinds of typical wetland plant,and the affecting factors were discussed.The Calorific values of Calamagrostis angustifolia and Carex pseudocuraica presented the same variation tendency: The calorific values of litters in three levels:0-10cm、10-20cm、20-30cm depth droped gradually going on with resolving.Layer of 30-40 cm appeared rise and fall wavily.The calorific values of these two kinds of litters appeared the same trend.The changes of litter calorific values of Carex lasiocarpa rose and fell greatly,the regularity was not obvious.更多还原
