    摘要:

    耦合InVEST模型和PLUS模型,本文计算了陕西省2000-2020年水源涵养量,并预测了未来2030年土地利用变化下的水源涵养量。结果表明:陕西省2000-2020年平均水源涵养量为132.25mm,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199.55×108m3,从行政区来看,安康市(308.96mm)水源涵养量最大。2030年陕西省水源涵养总量为285.16×108m3,相比2020年降低8.68×108m3。

    Abstract:

    The InVEST model and PLUS model were coupled to calculate the water conservation amount in Shaanxi Province from 2000 to 2020 and predict the water conservation amount under land use changes in the future in 2030. The results indicate that the average water conservation amount in Shaanxi Province from 2000 to 2020 was 132.25mm, with a spatial distribution characteristic of gradually increasing water conservation amount from north to south.From the perspective of vegetation types,forest land is the main body of water conservation in Shaanxi Province. The average annual water conservation amount is 199.55×108m3. From the administrative region, Ankang City (308.96mm) has the largest water conservation amount. The total amount of water source conservation in 2030 is 285.16×108m3,8.68×108m3 less than in 2020..
