摘　　要：近年来,由于人类各种活动的增加,使得湿地中陆源性溶解有机质(DOM)的含量在湿地总DOM中所占的比重不断增加,日益引起人们的关注。木质素为陆地维管束植物细胞壁的特有组分,也是湿地陆源性DOM的特有组分,在湿地环境中具有较高的化学稳定性和抗微生物降解能力,因此成为湿地中一种良好的陆源性示踪剂。利用木质素的这种独特性和稳定性,对湿地中陆源性DOM进行辨识已经成为现代研究的一个方向。本文主要对木质素作为陆源性DOM示踪剂的指示原理以及木质素在湿地陆源性DOM辨识中的具体应用进行了综述。总结提出了木质素作为陆源性DOM的示踪剂在湿地陆源性DOM识别研究中存在的问题,并对其研究前景进行了展望,为木质素在湿地中陆源性DOM的辨识提供理论参考。In recent years, the intensification of human activity has resulted in the increase of terrestrial organic matters in wetlands, which has received a wide concern from the public. Lignin is not only the component of the cell wall of terrestrial vascular plants, but also the component specific for wetland ter- restrial organic matters. It is highly stable al and resistant to microbial degradation in wetland environ- ment, thus may serve as a good terrestrial tracer in identifying the terrestrial organic matters in wet- land. Actually, the application of lignin to tracing terristorialterrestrial organic maters has evolved as a trend of modern researches. In this paper, we mainly addressed the application of lignin used as a ter- restrial organic matter tracer and its associating problems. We have also looked out the future of such trend, hoping to provide a theoretical reference for researching community.
