Abstract:environmental economics. Ecological location is one of important factors that influence the ecosystem service value. This paper took Beijing City as an example to conduct the research of ecological location correction of ecosystem service value. According to the resource scarcity theory, this paper plotted out the ecological location and assigned each ecological location a coefficient. Based on these coefficients, this research modified ecosystem service value of main types of land cover in Beijing, obtained from land use thematic may of 1980, 1995 and 2000, and gained the distribution of the value of ecosystem functions in Beijing in the three periods. The result showed that, the ecosystem service value of paddy field, forested land, shrub and water body dominate the whole ecosystem service value. The total ecosystem service value of each ecological location was increasing with the increase of the distance away from urban region. Form 1980 to 1995, there is decline in ecosystem service value of each ecological location, with a decrease of.21×107 Yuan in the whole ecosystem service value. Form 1995 to 2000, the whole ecosystem service value increased, but the value of 2000 is less than that of 1980, with a decrease of 3.07×106 Yuan.
