Abstract:

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.

摘要：

矿区是人类活动干扰最强的生态系统之一，矿区的开采利用对经济的发展起到了巨大的推动作用，但同时也对当地环境产生了重大影响。本文以平朔矿区为对象，采用了市场价值法、成本法和影子工程法等研究了该区域1985—2005年土地利用变化所引起的生态系统服务价值的变化。结果表明，1985—1990年矿区总的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，到2005年时为311 090.05万元。复垦地的增加带来了良好的生态效益，改善了生态环境，提高了生态服务价值，减少了因受损地增加而产生的负面作用。
