Analysis on the evolution trend of water resources and water environment in Xiangjiang River basin

摘要：

　　According to the daily flow data collected by three representative hydrological stations in the Xiangjiang River basin which are the Guiyang station in the upstream section,the Hengshan station in the midstream section,and the Xiangtan station in the downstream section,and the water environment data collected from the Hunan Water Resources Bulletin,Mann-Kendal method was used to analyze the changes of the annual average flow of the Xiangjiang River basin in the past 20 years as well as the variation of water environment quality in the whole year,flood season and non-flood season.Based on these analysis,the evolution trend of water resources and water environment in the Xiangjiang River basin is further forecasted.The results show that the annual runoff of the upper reaches of the Xiangjiang River basin tends to be stable,and the runoff of the middle and lower reaches is decreasing.The water quality of the Xiangjiang River basin got deteriorated from 1996 to 2010.A sudden change occurred around 2012,and the water quality of the basin gradually improved.
