摘要
Abstract
Water quality at five monitoring stations in the upper reach of the Chishui River in the flood season (July ), dry season (January ) and average season (October ) in 2010—2012 was analyzed for spatiotemporal patterns.Spatiotemporal variations in water quality were analyzed;pollution sources were identified coupling utilization of single factor water quality identification index and multivariate analysis.This will provide some theoretical basis for water management in the upper reach of the Chishui River.It was found that the water quality in flood,dry and average seasons were rather similar.Water quality at Maotai station was the most polluted,HN+4-N and fecal coliforms all exceeded standard for water environment function area. Water quality at other monitoring station satisfies the standard of water environment function area,Data indicated that pollution was mainly from agricultural runoff of non-point source,coal and liquor in flood seasons. The primary pollutants were potassium permanganate index, fecal coliforms, BOD5 , CODCr . Corresponding measures can be taken according to pollution source. Renovation of water environment, development of ecological agriculture,improvement of the wastewater treatment efficiency,and increased recognition of discharge of liquor factory were highlighted from watershed management perspectives.关键词
