摘要：

可溶性有机物质 (Dissolved Organic Matter)是森林生态系统主要的可移动碳库及重要的养分库。系统综述了森林生态系统 DOM的来源、组成、性质、季节动态 ;DOM释放与存留机制及影响因素 ;森林生态系统 DOM的流动及干扰对 DOM动态影响等。已有研究表明 DOM在森林生态系统 C、N、P循环、成土作用、污染物迁移等方面起着重要作用。今后森林生态系统 DOM的研究应集中于以下几方面 :(1 )确定森林生态系统中 DOM源和汇 ;(2 )评价森林水文条件对 DOM释放与存留的调节作用 ;(3)探讨全球气候变化对森林生态系统 DOM的影响 ;(4)可溶性有机氮 (Dissolved Organic Nitrogen)、可溶性有机磷 (DissolvedOrganic Phosphorus)动态与可溶性有机碳 (Dissolved Organic Carbon)动态的差别。
