Abstract:

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.

摘要：

研究土地利用变化对矿区生态系统服务价值的影响具有重要意义。本文以平朔矿区土地利用的动态数据为基础，对该矿区不同类型土地的生态服务价值及矿区总的生态服务价值进行研究。结果表明：1985—1990年矿区生态价值呈下降趋势，从31 270.98万元降至30 348.14万元；1990—2005年生态价值逐渐上升，2005年为311 090.05万元。矿区无复垦措施和有复垦措施两种情景设置结果显示：在完全没有复垦措施的情况下，矿区总的生态价值呈下降趋势，2005年仅为26 401.6万元；而在有完全复垦措施的情况下，总生态价值呈急剧上升状态，到2005年为49 835.55万元。说明土地复垦及生态重建工程对矿区的生态可持续发展起到重要作用。
