杉木根系残落物是森林生态系统的重要组成部分,其分解可以为土壤生物提供生存环境以及所需养分,还可改善土壤条件,有利于杉木的生长发育,提高其生物量,促进森林生态系统物质循环以及能量流动。根系残落物分解体现了养分回归土壤的速率以及土壤生物利用残落物的效率。本文分别从杉木根系残落物自身因素和环境因素出发,对其分解的影响机制进行综合归纳论述,探讨研究中存在的问题并提出展望。根系残落物分解会向土壤和大气释放养分,是森林生态系统中潜在的营养物质来源,了解杉木根系残落物动态分解对杉木人工林经营过程中养分循环的优化具有重要意义。
Abstract:Chinese fir root residues are an important part of forest ecosystems. Their decomposition can provide a living environment and nutrients for soil organisms, while improving soil conditions, which is conducive to the growth, development, and biomass accumulation of Chinese fir and promotes the material cycling and energy flow in forest ecosystems. The decomposition of root residues reflects the rate of nutrient return to the soil and the efficiency of soil organisms in utilizing the residues. This paper elucidates the influencing mechanisms of root residue decomposition in terms of their own factors and environmental factors, explores the problems in related studies, and makes an outlook on the future research in this field. Root residue decomposition releases nutrients to the soil and the atmosphere, serving as a potential source of nutrients in forest ecosystems. Understanding the dynamic decomposition of Chinese fir root residues is of great significance to the nutrient cycling in the management of Chinese fir plantations.
