ABSTRACT:
Scientific determination of ecosystem service values (ESVs) is the basis and premise of realizing sustainable management of the regional ecosystem. Therefore, it is of great significance to explore the dynamic evolution of ESV in Qinghai-Tibet Plateau (QTP) to maintain the plateau landscape diversity and ecological environment protection. This paper constructed a compre-hensive basin analysis perspective of horizontal distribution, vertical distribution, and basin gradient to analyze the dynamic evolution of ESV in the Yarlung Zangbo River Basin (YZRB). The results showed that: The total ESVs of YZRB increased from 1980 to 2015, in which the ESVs of grassland and water decreased, and ESVs of other sites increased. The changes in ESVs in different land-use types had obvious differences in basin gradients. In general, ESVs presented a stepwise distribution pattern of “upper
