摘要: 通过廊道系统自净和lysimeter渗滤实验进行了辽东湾芦苇湿地对陆源营养物质净化作用的初步研究.结果表明,营养物质N、P和CODcr在廊道系统中的自净率为 41.7%~64.71%.不同深度的土壤-芦苇系统对陆源营养物质N、P和CODcr的净化率为 60.0%~75.92%.N、P营养物质经湿地系统过滤后可满足海水水质 2类标准.通过收获地上部分生物量可使营养物质在陆地和湿地之间形成良性循环,不会造成污染物在湿地系统的过度积累.

关键词: 湿地, 陆源营养物质, 净化作用

Abstract: The preliminary study on purification function of reed wetland for nutrients from land sources were conducted by irrigation channels and lysimeters.The results show that the purification rates for N, P and CODcr are from 41.7%~64.71% in the channels and 60.0%~75.92% in the lysimeters.The contents of N and P reached the national second level standards of sea water after filtration by lysimeters.By harvest, the good recycle between wetland and land is formed without accumulation.
