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。

Abstract:Dissolved organic matter (DOM) was the primary active carbon pool in forest ecos ystems and played an important role in the cycling of carbon, nitrogen, and phos phorus, in soil formation and in the transport of pollutants. The aim of this re view was to summarize the origin, property and flux of dissolved organic matter in forest ecosystems. Recent studies showed that litter and humus were the most important DOM sources in forest ecosystems. The soil microbe was also considered as a potential, i mporta...
