[0002] The litter layer refers to the layer of organic matter formed on the surface of the mineral soil under the forest vegetation, also known as the dead vegetation layer, which includes undecomposed fallen objects and decomposed organic matter layers. The forest litter layer can be divided into three sublayers according to its degree of decomposition: the first is the undecomposed litter layer, which is composed of newly fallen leaves, twigs, fruits, bark, etc., and the original shape of the covering layer can still be identified; the second is the semi-decomposed litter layer, the covering layer of this layer has been partially decomposed, but their structure can still be distinguished; the third is the coarse humified litter layer, which has It is completely decomposed into mud and cannot be distinguished. As the main source of forest soil organic matter, it is of great significance to restore forest soil fertility, improve forest nutrition and increase forest productivity. Therefore, the study of the litter layer is of great significance to forest protection and forest ecology research.
