Abstract: Reservoir and its joint rivers have good space continuity, and the deterioration of the reservoir water was caused by the input polluted river. In this paper, water quality was examined in 61 sampling sites in Dahuofang Reservoir and its joint rivers. Cluster analysis and principle component analysis (PCA) were used to analyze the spatial characteristics and major pollutants of water quality both in the reservoir and its joint rivers. Cluster analysis showed that the reservoir can be divided into 3 typical areas including upstream, downstream and reservoir on the basis of the similarity water quality. PCA indicated that water quality in upstream and downstream were mainly both affected by ammonia, total nitrogen and CODCr. In reservoir area, it was mainly affected by temperature, pH, turbid, dissolve oxygen, conductivity ammonia and total nitrogen. Ammonia and total nitrogen both had significant impact on water quality in upstream, downstream and reservoir, with the concentration of ammonia was 0.06, 0.10 and 0.19 mg/L respectively, total nitrogen was 0.13, 0.16 and 0.26 mg/L respectively. Affected by the tributary inflow, the reservoir water quality had resulted in space difference, where Shehe bay is better than Hunhe bay. In Dahuofang Reservoir, the concentration of ammonia nitrogen and total nitrogen were negatively related with the distance to river bank. The concentration of dissolve oxygen and pH were negatively related with the distance to estuary. This indicated that the input amount of pollutant from joint riversand non-point source pollution around the reservoir had a certain effect on water quality of Dahuofang Reservoir. © 2016 by Journal of Lake Sciences.
