%X The temporal and spatial characteristics of surface water quality in Jiyun river are analyzed based on environmental measurement data.It was found that ground water quality of Jiyun river is deterioration from upper to lower part.Compared to the 1995 and 1990,there is no obvious change for most pollutants content except for the content of ammonia nitrogen.The reasons inducing the temporal and spatial change of surface water quality in Jiyun river are following:the land use change,such as increase of agricultural land and decrease of woodland or grassland,discharge of industry wastewatep and domestic sewage.
