The Three-River Headwaters Region(TRHR) of China is within the hinterland of the Tibetan Plateau.As the source of the Yangtze,Yellow(Huanghe) and Lancang(Mekong) rivers,the TRHR is of key importance to the ecological security of China and Southeast Asia.This paper quantified the indirect value of ecosystem services in the TRHR by using the replacement cost approach,opportunity cost approach and shadow project approach.The results showed that the indirect value of ecosystem services was some 1.74×1011 yuan in 2008,which included water conservation of 1.07×1011 yuan accounting for 61.38%,soil conservation of 4.60×1010 yuan accounting for 26.50%,carbon sequestration of 2.01×1010 yuan accounting for 11.56%,and air quality regulation of 9.56×108 yuan accounting for 0.55%.The results highlighted the role of the TRHR as the important birthplace of water sources and its outstanding contribution to water balance,water cycle regulation and regional hydrology improvement.Besides,the results offered good information to policy makers on regional sustainable management and payment for ecosystem service policies.
