Abstract Based on the main data source of Landsat TM remote sensing in 1987, 2000 and 2010 years, This paper studied the dynamic characteristics of alpine wetland ecosystem service values in Qinghai Lake basin through revising the ecosystem service value per unit area in China by means of biomass method. Results showed that the alpine wetland ecosystem service values from 1987 to 2010 years in Qinghai Lake basin increased to 232.34×108 Yuan RMB, with the annual mean rate of 0.18×108 Yuan RMB. Among them, the lakes, alpine meadow, alpine swamp and warm steppe ecosystem services value is the main part. Human activities and climate change drove its ecological service value dynamically. Ecological service function in the study area was mainly composed of hydrology regulation, waste management, climate regulation, and maintenance of biodiversity functions. Their service values accounted for more than 70% of the total value. Nearly 24 years, other ecosystem services' values were to some extent increased, except to the production function of the raw material. The most volatile in ecological service value were hydrology regulation, waste disposal and climate regulation functions.
