Impact of LUCC and Climate Change on Sediment Load in the Yanwachuan Watershed on the Losses Plateau
This paper studied on the sediment change based on the statistical analyses in Yanwachuan watershed from 1981-2012.Double mass curve was used to test the catastrophe point.We defined the time before catastrophe point as the base period and the time after as the changing phase.Origin 8.0 was used to fit the sediment data in the reference period and we built the model to make a quantitative analysis of the sediment during the changing phase.The results showed that the trend of runoff and sediment was declined,the correlativity of sediment and runoff was better.The year of 2001 was confirmed the catastrophe point and during the changing phase,the sediment discharge had reduced 0.25 million ton.
