摘要

[Objective]The study aimed to analyze water quality of origin flows of Hotan River using Nemorow pollution index method.[Method]Based on data monitored at four monitoring sections of Yorungkash River and Karakash River during 2001-2005,water quality of Hotan River was assessed by using Nemorow pollution index method.[Result]During 2001-2005,Yorungkash River and Karakash River had clean water reaching the first standard.Nemorow pollution index was 0.15-0.69 at the first section of Yorungkash River,and it was 0.23-0.46 at its last section;there were few changes in water quality at the last section,while Nemorow pollution index showed a downward trend at the first section.Nemorow pollution index was 0.23-0.65 at the first section of Karakash River,and it was 0.23-0.47 at its last section,showing a downward trend at its last section.[Conclusion]Water quality of Hotan River belonged to first-class clean water.更多还原
