The changes in land utilization have big influence over the ecosystem service function in mining area. This paper, based on land utilization data in Pingshuo mining area, studies the ecosystem service value in different land types and the total ecosystem value, indicates that the ecosystem service value had a decreasing trend during 1985 to 1990, from 312.7 million yuan to 303.48 million yuan, and a increasing trend during 1990 to 2005, up to 3110.9 million yuan. Two simulations with rehabilitation and without had been set to compare. Without rehabilitation, the total ecosystem value is decreasing, only 264.01 million yuan in 2005; while the total ecosystem value is increasing with rehabilitation, up to 498.36 million yuan in 2005, implying the rehabilitation plays a vital part in the sustainable development of ecosystem in mining area.

Mining area is one of strongest disturbed ecological systems by human being. People's mining has a great driving force to economy, but a big impact to the local environment. This paper, taking Pingshuo as a case study, applies marketing value method, cost method and mirror project method to study the ecological system service value changes triggered by land utilization changes during 1985 to 2005, with the results indicating that the ecological value fell from 312.71 million RMB to 303.48 million RMB during 1985 to 1990, slowly rose to 311.09 million RMB during 1990 to 2005. Rehabilitation led to a good ecological profit, which improved the ecological environment, increased the ecological service value, and mitigated the impact to surface.
