基于联合国千年生态系统评估的基本理念和评价框架,从供给服务、调节服务、支持服务和文化服务4个方面对河南省义马矿区单位面积的生态功能价值进行测算,并分析了义马矿区生态系统服务价值在2005—2012年间的演化过程及敏感因素。结果表明:(1)义马矿区单项生态服务价值在2005--2008年间,废弃物处理、水源涵养、娱乐活动和控制侵蚀呈正向变化,食物生产、生物多样性、空气净化、土壤保持、气候调节呈负向变化,在2008--2012年间,仅有土壤保持功能价值为负向变化,其他均为正向变化;(2)矿区生态系统服务总价值呈现出降低-上升-缓慢下降的趋势;(3)农田和水域为义马矿区生态系统服务价值最敏感的因素,即矿区实现可持续发展的关键举措是进行土地与生态修复和水资源保护。
Based on the framework of Millennium Ecosystem Assessment ( MEA), ecological function value of per unit area of Yima coal-mining area was calculated from the aspects of supply service, regulating service, sup- port service and cultural service. In addition, evolutionary process of ecosystem service value of Yima coal-mining area from 2005 to 2012 was analyzed. Results showed that among individual ecological service values from 2005 to 2008, waste treatment, water conservation, recreational activities and erosion control had a positive change, while a positive change. Resuhs also showed that total ecosystem service value of Yima coal-mining area presented a trend of decrease-increase-slow decrease. Finally, results showed that farmland and water area were the most sensitive factors to ecosystem service value of Yima coal-mining area, which meant that land and ecological restoration and protection of water resources were key measures to realize sustainable development Yima coal-mining area.
