杉木凋落物土壤生态功能研究进展

Research Advances in Soil Ecological Functions of Cunninghamia lanceolata Litters

凋落物作为连接植物与土壤的基本载体,在养分循环中起着至关重要的作用。目前国内外的研究主要集中于自然或人工林凋落物的产量、养分含量、能量流动及碳循环等方面,而针对杉木凋落物的土壤生态功能并未深入探究。通过查阅大量文献,在前人研究的基础上,文中简述了杉木凋落物的分解特性,详尽地阐述了杉木凋落物对于土壤物理、化学性质及土壤生物的影响,并在现有研究分析的基础上对今后凋落物研究的方向进行了展望。

As the basic carrier connecting plants and soil, litters play a crucial role in nutrient cycling.The present national and international researches are mainly focused on the litter quantity, nutrient content, energy flow and carbon cycle in natural or planted forests, but fail to describe the ecological function of soil for Cunninghamia lanceolata litters in detail.Based on the literature review, this paper briefly describes the decomposition characteristics of C.lanceolata litters, and elaborates on their effects on soil physical and chemical properties and the soil organisms.Finally, the future direction of litter research is prospected based on the existing research.
