The Mediterranean basin is considered one of the most vulnerable regions of the world to climate change and such changes impact the capacity of ecosystems to provide goods and services to human society. The predicted future scenarios for this region present an increased frequency of floods and extended droughts, especially at the Iberian Peninsula. This paper evaluates the impacts of climate change on the water provisioning and erosion control services in the densely populated Mediterranean Llobregat river basin of. The assessment of ecosystem services and their mapping at the basin scale identify the current pressures on the river basin including the source area in the Pyrenees Mountains. Drinking water provisioning is expected to decrease between 3 and 49%, while total hydropower production will decrease between 5 and 43%. Erosion control will be reduced by up to 23%, indicating that costs for dredging the reservoirs as well as for treating drinking water will also increase. Based on these data, the concept for an appropriate quantification and related spatial visualization of ecosystem service is elaborated and discussed.
地中海盆地被认为是世界上对气候变化最脆弱的地区之一，这种变化影响到生态系统为人类社会提供商品和服务的能力。该地区预测的未来情景显示，洪水的频率增加，干旱时间延长，特别是在伊比利亚半岛。本文评估了气候变化对人口密集的地中海流域水供应和侵蚀控制服务的影响。在流域尺度上评估生态系统服务及其制图，可以确定当前对河流流域的压力，包括比利牛斯山脉的源头地区。饮用水供应预计将减少 3%至 49%，而总水电产量将减少 5%至 43%。侵蚀控制将减少多达 23%，这表明需要增加疏浚水库和处理饮用水的成本。基于这些数据，详细阐述和讨论了生态系统服务的适当量化及其相关空间可视化的概念。
