摘要
2007年夏季和秋季,按照GB11607-1989《渔业水质标准》和GB3838-2002《地表水环境质量标准》,对陕西黄河湿地渔业水域环境质量的主要理化指标进行了现场监测,对渔业水域的主要水生植物进行了调查。结果表明:陕西黄河湿地渔业水域的池塘和大水面硫化氢(H2S)含量均符合标准,池塘和大水面的总磷(TP)及总氮(TN)均不符合标准。池塘和大水面渔业水域环境质量呈明显的富营养化现象,池塘比大水面富营养化现象严重,但湿地大水面的主要理化指标优于池塘,湿地大水面渔业水域生长的水生植物芦苇Phragmites australis和香蒲Typha orientalis对TP和TN具有一定的净化作用,通过监测分析提出了湿地渔业水域的保护措施。
In the summer and the autumn of 2007,the main physical and chemical indicators for environmental quality of the fishery waters in the Yellow River wetlands in Shaanxi Province were monitored,and the main aquatic plants in the fishing areas were surveyed according to GB11607-1989-＂Standards for Fishery Water Quality＂ and GB3838-2002-＂Standards for Surface Water Environmental Quality＂.The results showed that the content of hydrogen sulfide in the ponds and large fishery waters in Yellow River wetlands in Shaanxi was in consistence with the standards,but not for the total phosphorus and nitrogen contents.The environmental quality of the ponds and the large waters showed an obvious eutrophication,which was more serious in the ponds than in the large waters.The main physical and chemical indicators were better of the large waters than of the ponds.Furthermore,the aquatic plants Phragmites（Phragmites australis） and Typha（Typha orientalis Presl）growing in the large fishery waters of the wetlands had an effect of purification of TP and TN.
