摘要

在内蒙古皇甫川流域

利用凋落物样袋分解法对不同植被类型凋落物分解过程中营养元素的变化特征进行了研究。结果表明:在杨树叶、油松针叶和禾草3种植被凋落物分解过程中

营养元素随凋落物失重率的增高而降低

其中一部分营养元素回归土壤后

使凋落物样袋下相对应土层的营养元素含量提高;凋落物分解对恢复、补充和提高土壤肥力

防止水土流失

具有重要的实际意义。

Abstract

Studies on decomposing of litters and characteristic of nutritious elements in different were carried out in Inner Mongolia Huangfuchuan Watershed. The results showed that the nutritious elements in Populus simonii

Pinus tabulaeform leaf and Herbage decreased accompanied with the rising of weight loss rate. A fraction of litters being returned to the soil

led to the increase of nutritious elements in the corresponding soil horizon. The decomposing of litters play an important role in the respect of recovering

supplement and improvement of soil fertility.
