摘　　要：[目的]为估算陕西省水源涵养量。[方法]通过耦合InVEST模型和PLUS模型,计算陕西省2000—2020年水源涵养量,并预测未来2030年土地利用变化下的水源涵养量。[结果]陕西省2000—2020年平均水源涵养量为132.25 mm,空间分布特征为水源涵养量由北向南逐渐增强。从植被类型来看,林地是陕西省水源涵养量的主体,年平均水源涵养量为199.55×10^(8)m^(3);从行政区来看,安康市水源涵养量最大(308.96 mm)。2030年陕西省水源涵养总量为285.16×10^(8)m^(3),相比2020年降低8.68×10^(8)m^(3)。[结论]陕西省未来2020—2030年水源涵养量呈略微下降趋势。[Objective]This study was aimed to estimate the amount of water conservation in Shaanxi Province.[Methods]The InVEST model and PLUS model were coupled to calculate the water conservation amount in Shaanxi Province from^(2)000 to 2020 and predict the water conservation amount under land use changes in the future in 2030.[Results]The average water conservation amount in Shaanxi Province from^(2)000 to 2020 was 132.25 mm,with a spatial distribution characteristic of gradually increasing water conservation from north to south.From the perspective of vegetation types,forest land was the main body of water conservation in Shaanxi Province.The average annual water conservation amount was 199.55×10^(8)m^(3).From the administrative region,Ankang City had the largest water conservation amount(308.96 mm).The total amount of water source conservation in 2030 will be 285.16×10^(8)m^(3)and 8.68×10^(8)m^(3)less than that in 2020.[Conclusion]The water conservation amount of Shaanxi Province will show a slight downward trend from^(2)020 to 2030 in the future.
