Abstract

This study used satellite photos of 1985, 1990, 1994, 1999 and 2005 in Pingshuo mining area, for the purpose of researching on the change of Ecosystem Service Value (ESV) in the past 20 years. It calculated the change amplitude, change velocity and relative change rate of ESV and compared the Sensitivity Index (SI) of ESV coefficient. The result is that, the total ESV of Pingshuo mining area descended from 31270.98×104 Yuan in 1985 to 30348.14×104 Yuan in 1990. When the destroyed land had been reclaimed from 1990, ESV had been raised to 31109.05×104 Yuan in 2005. The change amplitude, change velocity and relative change rate of destroyed and reclamation land were the first and second highest among the types of land use in mining area. SI of dry land is the highest, while the destroyed land’s is the lowest. It could conclude that the ESV coefficient of mining area is inelastic. Reclamation should be strengthening in mining area in order to recover ecosystem efficiently.
