摘要
在镇江内江设置水质监测断面,分析水质常规指标,运用模糊综合评价的方法,评价镇江内江现有的水质状况。研究结果表明,内江水体污染程度相当严重,较大区域的水体为Ⅳ类,部分区域为Ⅴ类,总磷(TP)对水质的影响程度最大,其权重在各监测时期内各监测断面中均在30%以上,另外总氮(TN)指标也偏高,权重仅次于总磷(TP),最大达到30%多,也是内江水体的主要污染指标。
The water quality monitoring sections are set up, the indexes of routine analysis for water pollution are analyzed, and the state of water quality in Neijiang River is evaluated by the fuzzy conr/Jrehensive assessment method. The findings indicats that the water pollution de- gree in Neijiang River is quite serious, in which the water- quality stan ＇dards grade is IV level in wide range, and the partial regions being Vlevel; the effects of the total phosphorus （TIP） on water quality is severe and its weight at each monitor time is all above 30% in each monitoring section; moreover, the total nitrogen （TN） is also high, its weight being second only to TP and most greatly achieving 30%, is also the main pollution index in Neijiang River.
