摘    要:通过廊道系统自净和lysimeter汉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地滤后可满足海水水质2类标准,通过收获地上部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

关 键 词:湿地  陆源营养物质  净化作用  海水  水质

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.
Keywords:Wetland  Nutrients from land sources  Purification function
