盐城大纵湖疏浚前后沉积物-水界面环境化学变化
Changes in environmental chemistry at water-sediment interface before and after dredging of Dazong Lake in Yancheng City
摘要
Abstract
Sediment cores from Dazong Lake in Yancheng City before and after dredging of the lake were simulated using microelectrode technology.The changes in pH, Eh, and DO in the profile of the upper 2-cm surface layer were studied before and after dredging , in order to investigate the effect of sediment dredging on the control of eutrophication in shallow lakes.The results show that there are significant differences in the values of Eh and pH measured by traditional methods and the microelectrode technology , which plays an important role in micro-scale research.The thickness of the oxygenated layer of sediment before and after dredging were 8 mm and 13 mm, respectively, and the changes in pH, Eh, and DO before and after dredging can help control the eutrophication in shallow lakes.关键词
