中文摘要:

运用市场价值法、机会成本法、恢复费用法和影子工程法等生态系统服务价值评价方法,结合实地调查,对1949—2006年北京市门头沟区煤矿资源开采及其生态系统服务损失进行了系统评估.结果表明:研究区煤矿开采主要导致固废处置与压占损失、塌陷区复垦成本与粮食损失、水源涵养损失、居民搬迁损失和水土流失损失;研究期间,门头沟区煤炭开采所造成的生态系统服务损失价值约543亿元,是其市场销售价值(59亿元)的9倍左右,且其很难或需要相当长时间才能得以恢复.

英文摘要:

By using the evaluation approach of ecosystem services ( including market value, opportunity cost, restoration cost, and shadow project approaches) , and combining with situation investi-gation, the ecosystem service loss in Mentougou District of Beijing City caused by coal resource exploitation in 1949-2006 was systematically evaluated. In the study area, coal mining mainly in-duced the cost increase of solid waste disposal and sink reclamation, and the losses in food production, water self-preserving, residents moving, and water and soil resources. The ecosystem service loss caused by the coal mining in 1949-2006 was about 54. 3 billion Yuan RMB, approximately 9 times high of its market economic benefit (5.9 billion Yuan RMB). It was very difficult or needed a long time to restore the damaged ecosystem.
