Quantitative assessment of ecosystem services is a precondition for scientific management of ecosystems, and hence of great significance to guaranteeing sustainable development and human well-being of a region. So, based on the Integrated Valuation of Ecosystem Services and Trade-offs model (InVEST) and the Conversion of Land Use and its Effects at Small Region Extent model (CLUE-S), quantitative assessment of the three ecosystem services of the Wuma River Valley, i.e. water yield, nutrient translocation and sediment retention, under the present land cover and that in 2030, encompassing two scenarios, that is, scenario of economic development(SED) and scenario of ecological protection(SEP). Results show that at present, the total water yield, the total outputs of nitrogen and phosphorus, and the total sediment retained of the Wuma River Valley is about 2.7×108 m3, 630 t, 142 t and 2×108 t, respectively, and will remain almost unchanged in the SED of 2030, but about 600×104 m3, 34.8% and 35.4%,and 0.7×106 t higher, respectively, in the SEP of 2030. Generally speaking, the three kinds of ecosystem services of the Wuma River Valley are closely related to land cover, and will significantly be improved in the SEP of 2030. This study may serve as reference for further efforts on evaluation of ecosystem services and formulation of development plans for the Wuma River Valley.
