Nitrogen Pollution of Streams in Wuyishan National Key Scenic Area
-
摘要: 为了解武夷山风景区溪流污染状况,2008~2009年间对武夷山风景区溪流水体中TN、NH3-N、NO3--N和NO2--N含量进行了连续监测,分析该流域溪流水体中氮素含量的变化特征。结果表明,景区溪流水体中氮素污染存在季节变化特征,NH3-N丰水期和枯水期均高于年平均值,NO3--N丰水期低于年平均值,枯水期高于年平均值。崇阳溪、黄柏溪TN、NO3--N污染较重;除NH3-N较高外,下梅溪各氮素污染均较轻;九曲溪各氮素污染较轻。Abstract: Nitrogen pollution of streams in Wuyishan National key scenic area was studied.Variations on TN,NH3-N,NO3--N and NO2--N were analyzed through continuous monitoring between 2008 and 2009.The results showed that the nitrogen pollution varied with the season.The concentration of NH3-N in either the flood or dry season was higher than the annual mean.That of NO3--N in the dry season was also higher than the annual mean.But that in the flood season was lower than the annual mean.Among the streams,the TN and NO3--N pollution in Chongyangxi Stream and Huangboxi Stream were more severe than in Jiuquxi Stream.The nitrogen pollution levels,except NH3-N,in Xiamei Stream were low.
