Thirty-three water sampling sites in Heihe River of the upper and middle reachers were set to characterize its water quality with spatiotemporal distribution. Water sampling trips were conducted in May (wet period), August (flow period), December (dry period) of 2017. Spatial and seasonal variations of water quality were analyzed by using the multivariate statistical methods and water quality were assessed by employing the comprehensive water quality identification index. The results indicated that the main types of water quality in the region were Class II and Class III, it also had a certain space-time differentiation. In temporal terms, the order of pollution was dry period > wet period > flow period; the spatial pollution situation was the upper tributary > the lower main stream > the middle reaches. According to landscape difference, the sampling sites were divided into 4groups:grazing and industrial area (Group A), reservoir area (Group B), agriculture and urban area (Group C). The results of factor analysis and APCS-MLR show that NH3-N, BOD5 and CODMn were typical pollutants in this region, and the pollution sources of group A were mainly from organic matter, followed by nutrients; the water quality of group B was mainly polluted by the accumulation of organic matter and nutrients, while the influence of natural factors were relatively weak; group C was mainly polluted by biochemistry, followed by non-point source nutrients pollution. The results show that human activities were still the main factors affecting the deterioration of water quality. Although the interception effect of dams could improve the quality of discharge water, the pollutants accumulated in the reservoir area all the year round have the potential risk of secondary pollution with the change of environment, such as the activation and release of nutrients in sediments.
