Spatial and temporal quality of surface water at Wuyishan national park

Based on the data collected at 8 monitoring locations in Wuyishan National Park in different seasons from 2008 to 2009,the spatial and temporal characteristics of the surface water quality in the area were compiled.The results showed that the water qua1ity was significantly poorer in upstream;NH3-N,TP,NO3--N were significantly higher during dry seasons;and,TN and CODMn were higher in flood season,as the non-specific pollution could be induced by rain falls.The quality variations of the surface waters in the area were attributed to the geological and hydrological factors,human activities,as well as agricultural practices.
