Abstract: Because of the interference of human activities in the grassland ecosystem, grassland degradation intensifies. Scientific valuation of grassland ecosystem services is of great significance for grassland conservation and management. Through the integration of multi-source, multi-scale and multi-process ecological environment data in Qinghai Province, and combined with large-scale field survey data, both specific and comprehensive databases were set up. Based on the Millennium Ecosystem Assessment (2005) classification system and Costanza’s classification methods of ecosystem services, we selected the Qinghai ecosystem services evaluation index system according to the characteristics and ecological status of ecosystem in Qinghai, and developed a data-model fusion platform to quantify the values of Qinghai grassland ecosystem services during 1998-2012. It consists of 16 kinds of services, for example, solid carbon release oxygen, hydrology regulation, soil conservation, and biodiversity etc. With the support of data, the ecosystem services valuation could have higher time resolution, reflect more ecosystem processes, and become more intelligent in the future. The results showed that the total value of grassland ecosystem services in Qinghai was between 234.997-337.449 billion yuan during 1998-2012, with the mean value of 293.563 billion yuan and 928.7 thousand yuan per hectare, which is 1.55 times of Qinghai Province’s GDP in 2012. Finally, based on this data, we proposed Qinghai grassland ecosystem adaptive management strategy to provide the basis and decision support for the ecological province strategy of Qinghai.
