Abstract

Abstract:

Annual runoff and annual suspended sediment loads at five hydrological gauging stations (Waizhou, Meigang, Lijiadu, Hushan and Datong) in the five tributaries of the Poyang Lake Basin (Ganjiang River, Fuhe River, Xinjiang River, Raohe River and Xiushui River) were analyzed using Mann-Kendall trend test and linear regression method. The results indicate that (1) the changing patterns of runoff and sediment loads are different over the Poyang Lake Basin. No significant trend is found for annual runoff at all the stations at >95% confidence level. However, the changes of sediment loads demonstrate different pictures in the Poyang Lake Basin. The sediment loads show a decreasing trend at Waizhou, Meigang and Hushan stations (the increasing trend of Waizhou station is significant at > 95% confidence level after around the year 1998), but an increasing trend at Ljiadu and Xiushui stations; (2) the forest coverage changes have greater impacts on sediment load than on the runoff; extensive deforestation contributed less to the increase of sediment loads in 1958. Large-scale deforestation caused significant increase of sediment loads during 1971-1985; (3) Hydraulic facilities, especially water reservoirs, exerted more influences on sediment load changes than on runoff, being the major cause next to the decreasing trend of sediment loads. The results of this study are of great practical significance to a better understanding of the hydrological responses to climate changes and human activities across the Poyang Lake Basin, as a freshwater wetland in China.
