Abstract:: Sandy soil of Poyang Lake is located in the south of China. Available water holding capacity of the sandy soil in four different plantation types was analyzed with method of pedotransfer functions. The results showed that ME and RMSE of Rawls model were 0.005 8 and 0.001 0, respectively, suggesting that Rawls model exhibited the higher projection accuracy, and was much fitter for estimating available soil water holding capacity of sandy soil in Poyang Lake region than Saxton model, Batjes model and Minasny model; the soil field capacity under different types of vegetation decreased in the order: Pinus elliotii > Fructus viticis > Robinia pseucdoacacia > natural grass; according to the values estimated by Rawls model, the permanent wilting point of soil under different types of vegetation decreased in the sequence: Robinia pseucdoacacia > Pinus elliotii > Fructus viticis > natural grass, the available water holding capacity of soil decreased in the order: Pinus elliotii > Fructus viticis > Robinia pseucdoacacia > natural grasst.
