Abstract:A system of candidate indices, including physical-chemical parameters for water quality, parameters for sediment quality, aquatic organisms indices and physical habitat quality indice were set based on monitoring data collected from the river in Tongling area in 2010. Principal component analysis (PCA) and correlation analysis were used to select twenty parameters from thirty candidate parameters, and an integrated assessment index system was incorporated. The health level at each sampling site was analyzed using synthesis index based on standard variance method. The results showed that 2 of 60 sites were “healthy” level, 16 were “sub-healthy” level, 33 were “poor” level, and the last 9 were “sick” level, which suggested the serious degradation of river ecosystem in Tongling. Mining activities, agricultural non-point source pollution and domestic waste water were the main factors impacting the river healthy.
