拉林河流域省界缓冲区水质现状评价及变化趋势分析
Water Quality Status Evaluation and Dynamics Analysis of Provincial Boundary Buffers in Lalin River Basin
摘要
Abstract
Based on the water quality monitoring data from 2007 to 2015,water quality up-to-stand-ard situation and dynamic trend of 4 provincial boundary buffers in Lalin River Basin were evaluated and analyzed by single factor index method.The results indicate that Jihei Buffer 1 of Lalin River and Maoniu River Jihei Buffer can meet water quality standards of water functional zone,while water quality up-to-standard situation of Lalin River Jihei Buffer 2 is relatively poorly qualified,and the factors exceeding the standards are ammonia nitrogen and total phosphorus,which exceed the standards more than six months a year.The maximum value of ammonia nitrogen can reach more than 1.4 times than that of the standard,while the total phosphorus is 2.55 times.The water quality of Lalin River Jihei Buffer 2 from 2007 to 2015 kept level Ⅲ-Ⅳ,the reasons of which are ammoniac nitrogen pollution in dry season and COD pollution in rain season,respectively.Concentration of ammoniac nitrogen in dry season exceeds averagely 0.07 to 1.2 times,while concentration of COD in rain season exceeds averagely 0.5 to 1.3 times.关键词
