Abstract
Based on the investigation and monitoring of water quality of Hefang Reservoir,the single factor and eutrophication evaluation on the current water environment was given.The results show that total phosphorus(TP) in most water areas was below the Ⅲ grade,total nitrogen(TN) was between Ⅱ-Ⅲ grade,and the TP was obviously beyond the standard,keeping at the stage of change from nutrion to eutrophication.In addition to natural factors,increasing human activities and mismanagement were major factors that levels of nutrients were higher in the reservoir.
