内梅罗法对侗河国家湿地公园地表水的环境质量评价

在侗河国家湿地公园9处地表水监测断面取水样进行水质监测分析,测定pH、DO、CODCr、BOD5、NH4-N、Cr6＋、Pb、Cd、As、Hg共10项水质指标,对侗河国家湿地公园地表水的环境质量进行评价。结果表明,9处监测断面中矮寨多样性保护区受到重污染,而李家寨、司马河皆受到轻微污染,其他6个监测断面水质良好。

Surface Water Environment Qualities Assessment of Dong River National Wetland Park

The water samples was took from nine monitoring？points in Dong？River National？Wetland Park, and ten water quality factors were analysised（including pH, DO, CODCr,BOD5,NH4-N, Cr6 ＋,Pb, Cd, As, Hg）. The relative pollution values for each individual factors were calculated by single factor assessment method, and the comprehensive environmental pollution indexes were abtained with the way of Nemerow pollution index. Thus, the water qualities in the Dong River National Wetland were evaluated to determining the extent of the contamination and major pollutants. The results showed that the pollution in Aizhai diversity protection area was moderate, and Lijiazhai,Sima river were subject to slight pollution, and the other six monitoring sections showed good water quality.
