Abstract

A comparative description of the structural and functional organization of plant debris and forest litter during natural postagrogenic reforestation in the 12-, 40-, and 100-year-long chronoseries of ecosystems is given. With the increase in the age of forests, the total reserves and diversity of litters rise; and the portion of easily decomposed components and their pH and ash content become smaller. The grass ground cover is replaced by grass–dwarf-shrub cover, which indicates a decrease in the trophicity of ecosystems. The properties of forest litter are adequately reflected in the ground cover composition. Forest restoration is accompanied by a regular decrease in the decomposition intensity of the ground detritus and in the rate of the biological cycle. The spatial differentiation of litters plays a role of a trigger for the subsequent divergence of soil organic profiles.

南方针叶林造林后造林过程中植物残渣输入动态和森林凋落物的某些特性

摘要

给出了在12年，40年和100年时间序列的自然生态系统中自然农业后再造林期间植物碎片和森林凋落物的结构和功能组织的比较描述。随着森林年龄的增加，枯枝落叶的总储量和多样性增加；并且易于分解的成分的部分及其pH和灰分含量变小。草地覆盖被草地矮灌木覆盖所取代，这表明生态系统的富营养度降低了。森林凋落物的性质充分反映在地被植物成分中。森林恢复伴随着地面碎屑分解强度和生物循环速率的规律性降低。
