    摘要:

    将InVEST(integrated valuation of ecosystem services and tradeoffs)模型中的产水量模型应用于太湖流域,定量评价太湖流域的水源涵养能力及其变化特征。结果表明:总产水量变化上,1990—2010年太湖流域生态系统总产水量波动性明显;空间分布上,南部地区单位面积的产水量较高,山区丘陵地带产水量比平原地带高。流域水源涵养能力分异性特征明显,降水量较土地利用/覆被更显著地驱动产水量的变化。

    Abstract:

    The water yield model of integrated valuation of ecosystem services and tradeoffs(InVEST)model was employed to estimate the water source conservation capacity of the Taihu Lake Basin and analyse its variation characteristics. The results show that the total water yield of the Taihu Lake Basin fluctuates obviously from 1990 to 2012. Water yield per unit area in the southern region is higher. The water yield of hilly area is higher than that in plain area. The differentiation of the water source conservation capacity of the Taihu Lake Basin is obvious. Compared with land use/land cover, rainfall significantly drives the change of water yield.
