| 摘 要： | 目前水溶性有机质（Dissolved Organic Matter)已逐步成为陆地生态系统中的一个研究热点。系统地评述了陆地生态系统中DOM的组成特点及其环境效应。尽管关于陆地生态系统中DOM的研究还不完善，至今对其性质，组成和分类方法等问题看法不一，但现有结果已经表明DOM是一种十分活跃的重要化学组分，它对陆地生态系统中污染物质的溶解，吸附，解吸，吸收，迁移和生物毒性，微生物活动以及土壤形成过程等均有显著的影响。影响DOM在地生态系统中的环境效应的主要因素包括：DOM与污染物的络合作用，污染物溶解／沉淀作用，土壤对DOM的吸附作用，土壤质地，酸碱缓冲作用等。

| Abstract: | Researches on dissolved organic matters (DOMs) have been increasing in water and soil studies since the concept of DOM was proposed in 1970's. Although most former researchers considered that humic substances might substitute soil organic matters in liquid phase, more and more later studies made sure that DOMs, which were water extracted, could represent soil organic matters in liquid phase more properly than humic substances. Results of IR, NMR, RPLC and other spectrum analyses revealed that there were gre... |
