In order to understand the effect of different afforestation models on soil fertility of artificial water conservation forest, in August 2010, we chose three afforestation models: Pinus tabuliformis+Acer elegantulum+Amorpha fruticosa L.(Ⅰ), Pinus tabuliformis +Quercus mongolica+ Acer elegantulum(Ⅱ) and Amygdalus davidaiana+Castanea mollissima(Ⅲ) which were planted in Experimental Area of Artificial Water Conservation Forest in Taishitun town, Miyun county, Beijing, 2008, set three plots in corresponding afforestation models: standard one(S1), standard two(S2) and standard three(S3). The soil fertility of the three models of water conservation forest was evaluated by applying descriptive statistical analysis. The results show that: the order of soil organic matter status in each forest is Ⅱ>Ⅰ>Ⅲ, the organic matter content of S3 was 11.3 g/kg, which was 54.3% and 54% lower than that of S1 and S2, respectively; the oder of total N and total K contents is Ⅰ>Ⅱ>Ⅲ, the contents of total N in Ⅰ, Ⅱ and Ⅲ were and 1.63 g/kg, 1.34 g/kg and 0.80 g/kg; the contents of total K in Ⅰ, Ⅱ and Ⅲ were 2.65 g/kg, 2.32 g/kg and 1.71 g/kg, respectively; the contents of the available K in Ⅰ, Ⅱ and Ⅲ were 48.45 mg/kg, 96.65 mg/kg and 37.75 mg/kg. The botanic species is abundant, forest canopy closure is high and quantity of litter accumulation is much in the mixed needleleaf and broadleaf forest, which significantly improves soil fertility in artificial water conservation forest.
