摘要
Ecosystem services emerged as a concept to bridge ecosystem conservation and the sustainable use of natural resources. Given the limited funding and resources available for ecosystem conservation, fully understanding and identifying the temporal-spatial patterns of ecosystem services can help establish a cost-efficient ecosystem conservation strategy. Although studies have indicated globally important ecosystem services on the Qinghai-Tibetan Plateau (QTP), key ecosystem services, such as carbon storage, water provision and habitat quality, have not been spatial-explicitly quantified, leading to a lack of understanding of key spatial patterns for conservation of this unique alpine ecosystem. To fill this gap, these three key ecosystem services were simulated for the QTP rangelands by using the Integrated Valuation of Ecosystem Services and Trade-off model, and the hotspots of those ecosystem services were evaluated and identified. It was shown that alpine meadows played a key role compared with alpine steppe and alpine desert in providing the ecosystem services of water provision, carbon storage and habitat quality in the alpine rangelands of the QTP. In addition, it was shown that there had been a considerable decrease in both the potential and the protected hotspots of ecosystem service between 1990 and 2000, implying that the existing conservation system (i.e. National Nature Reserves) could not effectively maintain these hotspots and that there was a need to restore those degraded rangeland ecosystems within the existing conservation system. The large-scale spatial heterogeneity among the different ecosystem services found in this study can be used to inform a more comprehensive conservation strategy for the provision of ecosystem services as well as biodiversity in the QTP rangelands.
