采集7个断面水样并监测了其总磷(TP)、叶绿素a (Chl-a)、高锰酸钾指数(CODMn )、总氮(TN )。利用所得数据,采用模糊数学法综合评价了九龙江(芗城段)水体富营养化程度。结果表明:九龙江(芗城段)富营养化基本为Ⅴ级,个别断面富营养化为Ⅵ级或偏向Ⅵ级。
採集7箇斷麵水樣併鑑測瞭其總燐(TP)、葉綠素a (Chl-a)、高錳痠鉀指數(CODMn )、總氮(TN )。利用所得數據,採用模糊數學法綜閤評價瞭九龍江(薌城段)水體富營養化程度。結果錶明:九龍江(薌城段)富營養化基本為Ⅴ級,箇彆斷麵富營養化為Ⅵ級或偏嚮Ⅵ級。
채집7개단면수양병감측료기총린(TP)、협록소a (Chl-a)、고맹산갑지수(CODMn )、총담(TN )。이용소득수거,채용모호수학법종합평개료구룡강(향성단)수체부영양화정도。결과표명:구룡강(향성단)부영양화기본위Ⅴ급,개별단면부영양화위Ⅵ급혹편향Ⅵ급。
The water was sampled from seven sections of Jiulong River.The total phosphorus (TP),chlorophyll-a,total nitrogen (TN),CODmn were tested.Fuzzy mathematic method was employed to assess the water entrophi-cation of Xiangcheng section in Jiulong River.The results showed that the water entrophication was the fifth grade, and one of seven sections can reach the fourth grade.
