基于模糊数学的黄河内蒙古段水环境质量评价
Assessment of Water Environmental Quality in Inner Mongolia Section of Yellow River Based on Fuzzy Mathematics
摘要
Abstract
Objective] The sampling data from 24 cross sections of 5 monitoring sites ,including Sansheng‐gong ,Sanhuhekou ,Baotoudengkou ,Zhangliwenyao ,Lama Bay ,were used for studying the water quality of Inner Mongolia section of the Yellow River .[Methods] Choosing the dissolved oxygen(DO) ,chemical oxy‐gen demand(COD) ,ammonia nitrogen ,total phosphorous(TP) and total nitrogen(TN) to evaluate the water quality of the Yellow River by means of comprehensive assessment of fuzzy mathematics .[Results] DO was between 7 .2 and 8 .1 mg/L ,which indicated that the water quality of the Yellow River belong to class I . COD varies between 17 and 33 mg/L ,indicating the water quality between the class Ⅲ and Ⅴ .Ammonia nitrogen varies between 0 .5 to 1 .3 mg/L ,water quality was within the class Ⅱand Ⅲ .TP was between 0.12 to 0 .28 mg/L ,water quality between the class Ⅱ and Ⅲ .TN was between 1 .4 to 2 .7 mg/L ,and water quality was the class Ⅳ ,even occasionally worse than that of the class Ⅴwater quality standard .COD and TN were the main pollutants .The water quality of Yellow River in Inner Mongolia are roughly in the classⅢ or Ⅳ ,and its vale varies between 3 .3 to 4 .2 mg/L .[Conclusions] Through the evaluation ,it is found that the water quality in the Inner Mongolia section of the Yellow River is gradually deteriorating .The main reason is the import of foreign pollutants .关键词
