This study was conducted on the basis of Chinese terrestrial ecosystem service value equivalent. Considering that ecosystem services vary in different time and different space, ecosystem service evaluation model was improved on time and space scale in this paper. Thus the change of value equivalent that was resulted from social development, resource scarcity change and spatial heterogeneity could be reduced. Then the Loess Plateau ecosystem service value dynamic evaluation model was built. Based on the model, we can analyze the ecosystem service value change characteristics on time and space scale. The total value of Loess Plateau was 633.391 billion, 767.995 billion and 939.046 billion in 2000, 2005 and 2010, respectively. The total value increased by 48% from 2000 to 2010. The value of soil conservation which is provided nearly 80% by forestland and grassland is the highest of all the ecosystem service values. So, the key to control soil erosion in Loess Plateau is to maintain and improve the quality of forestland and grassland. If we analyze the ecosystem service value in space scale, we can find that the higher ecosystem service values distribute in Shanxi, He’nan and the central south of Shannxi. And the growth rate of neimenggu’s service value was the first in the Loess Plateau. There were two reasons for the increase of ecosystem service values, one is the contribution of ecological protection measures, such as returning farmland to forestland and grassland, Sanbei shelter forest, the other is human pay more attention to ecological environment.
