In-depth study of the spatial-temporal change process of the ecosystem service value in Loess Plateau reveals the evolution of the ecological environment in the region, which is of great significance to the improvement and protection of the ecological environment in Loess Plateau. In this paper, based on comprehensively considering the spatial heterogeneity and temporal evolution of ecosystem service, the authors selected the Loess Plateau ecosystem service value dynamic evaluation model to assess the ecosystem service value in Loess Plateau. The ecosystem service value variability index was used to assess the impact of land use change on ecosystem service value and the environmental economy coordination degree index(CDEE) was used to evaluate the coordinating relationship between eco-environmental quality and social and economic development in Loess Plateau. The results show that, from 2000 to 2010, the ecosystem service value of Loess Plateau increased by 48%. This is mainly due to the desertification control in the Loess Plateau which had led to an increase in regional vegetation coverage and a corresponding increase in ecosystem services. The ecosystem service value change rate in grassland was the highest (13.45). The CDEE was 0.115 3 in Loess Plateau from 2000 to 2010, which was at a low level of coordination. This study can provide a scientific basis for ecological environment governance and evaluation of protection effectiveness in the Loess Plateau.
