摘要
凋落物分解可释放养分维持森林生态系统养分平衡和正常的物质循环,也释放化感物质影响伴生植物生长发育,在群落竞争和种群调节中具有重要生态作用。为林木凋落物分解和化感研究提供新思路,从林木凋落物分解影响因素、养分释放特征及对土壤生态环境和植物生长发育影响等方面对林木凋落物分解及化感作用的研究进展进行概述,并对未来凋落物分解研究进行展望。
Litter decomposition can release nutrients to maintain nutrient balance and normal substance circulation of forest ecosystem,meanwhile,release allelochemicals affecting the growth and development of associated plants.It plays an important ecological role in community competition and population regulation.The research progress on forest litter decomposition and its allelopathy is reviewed from aspects of factors influencing litter decomposition,nutrient release characteristics and its effect on soil ecological environment and plant growth and development to provide new ideas for the study of forest litter decomposition and its allelopathy,the future research on litter decomposition is prospected as well.
