摘要
有机碳是地表各种环境介质中的重要化学组分,是生态系统中能量与物质循环的重要介质。有机碳作为河流输移的主要物质,输运过程中对周围环境产生的效应不容忽视。本文结合近年来国内外研究动态,探讨并总结了河流作为碳源/汇角色的作用,有机碳对重金属迁移过程和水体生产力产生的影响;指出随着人类活动影响的加剧,河流有机碳正发生着显著变化,并影响到我们自身的生活;总结了传统的研究有机碳的方法,并对正在发展的研究方法做一下探讨。
Organic carbon is an important component in various environment media of the earth＇s surface. As the primary substance transferred by rivers, the effect of organic carbon on sunrounding environment during the transferring process is nonnegligible. Referring the recent researches home and abroad, This paper discusses and summarized the role of the rivers as the source and sink of carbon as well as the effects of riverine organic carbon on heavy metals emigration and river productivity. It points out that with the intensification of human activities, the riverine organic carbon is significantly changing and then affecting our own lives. The traditional research methods of organic carbon are summarizes, and the research methods undergoing developing are discussed.
