Research on the Temporal and Spatial Variation of Water Quality of Pi River in Luan City

WANG Wan-fen et al (Department of Urban Construction and Environment Science,West Anhui University,Luan,Anhui 237012)  
By using the improved grey correlation analysis method,the water quality of Pi River in Luan City during 2001-2007 were roundly evaluated and analyzed.Centralization method was used to make the non-dimensional treatment of series.The point-to-interval distance method was used to calculate the correlation coefficient.It overcame the deficiencies of the traditional grey correlation analysis method to make the evaluation results more reasonable and feasible.The results showed that the water quality of Pi River in 2001 wasⅢ-grade,belonging to slight pollution.The water quality in 2002 and 2004 was cleaner,belonging to Ⅱ-grade.The water quality in 2002 was better than that in 2004.The water quality in 2003,2005 and 2006 was clean,belonging to Ⅰ-grade.And the water quality in 2003 was better than that in 2005 and 2006.The water quality in 2007 was Ⅲ-grade,belonging to slight pollution.The water quality of Pi River during 2001-2007 could reach its planning targets.The water quality was gradually improved from 2001 to 2006,but it had a rebound trend in 2007.In 2007,the water quality in the sections of Yaogangzui Bridge and Dadiangang were Ⅰ-grade,that in the sections of Guanghua Factory Ferry and Xinan Ferry were Ⅱ-grade.The water quality in each section was cleaner.In 2007,the water quality of Pi River in dry season,flood season and usual discharge season were Ⅰ-grade,Ⅱ-grade and Ⅲ-grade respectively.The overall water quality was cleaner.But the water of Pi River in usual discharge season was slightly polluted.
