摘要
林木细根在森林生态系统能量流动和物质循环中起着重要作用。近年来,随着人们对细根功能的深入认识和研究方法的发展,细根研究成为当今森林生态学的研究热点之一。本文简要介绍了细根研究普遍采用的研究方法及其优缺点、适用性;并综合前人的研究成果,对林分细根生物量、分布、分解和周转以及细根在养分循环中的作用等研究结果进行综述。
Fine-root plays a significant role in energy flow and nutrient cycling. In recent years, with the reseacher＇s full realization for the importance of fine-root and the development of study methods, the fine-root has become one of hot spots of forest ecology. This paper introduced briefly meet of methods used in fine-root researchs, their advantages and disadvantages, suitablility and comparison between different methods. The fine-root research results of biomass and its vertical distribution, decomposition and turnover were also reviewed.
