摘要：We assessed the effects of landscape change on the climate regulation ecosystem service in amountain river basin of Portugal, through the quantification, valuation and mapping ofcarbon sequestration and storage. The analyses were based on land use and land cover(LULC) changes that took place between 1990 and 2006 and on expected changes defined bythree LULC change scenarios for 2020. We used the Integrated Valuation of EcosystemServices and Tradeoffs model for scenario building and carbon assessment and valuation,and several modelling tools to assess past, current and future carbon in four different pools.Soil organic carbon data was obtained through an extensive sampling scheme across theentire study area. Recent (1990–2006) and expected landscape changes (2006–2020) affectedconsiderably carbon sequestration and storage. Observed landscape changes generally promoted carbon sequestration and storage, and had a positive effect on the climate regulationecosystem service, both biophysically and economically. Expected LULC changes furtherextend the capability of the landscape to increase carbon sequestration and storage in thenear future. The carbon sequestered and stored in vegetation and soil contributes to avoidsocio-economic damages from climate change, while increasing the economic value ofparticular LULC classes and the whole landscape. These results are essential to inform landplanning, especially on how, where and when changes in landscapes may affect the provisionof the climate regulation ecosystem service.
