Abstract:

Coal industry as a vital economic industry promotes economy, but deteriorates the ecological environment in mining areas. Studying the values of ecological system function service can clearly display the influence of mining activities to the environment. This paper, based on the ecological system service function classified by Constanza, combines the natural environment, selects production ability, air conditioning ability, water restoration, soil protection and tourism to study the service function values of ecological system with results indicating that mining with rehabilitation is much higher than mining without rehabilitation in ecological service values. It means land rehabilitation effectively increases the service values of ecological system in mining areas.

Key words: mining areas, service function of ecological system, land rehabilitation

摘要：

煤炭工业作为我国重要的经济产业，在促进国民经济发展的同时，也严重破坏了矿区的生态环境，矿区生态系统服务功能价值的研究，能够比较精确地体现出采矿活动对生态系统服务功能的影响。以内蒙古胜利东二号露天煤矿为例，根据遥感影像以及矿区开采工序，以Constanza划分的生态系统服务功能为基础，结合研究区的自然环境特点，选取与胜利东二号矿相关的生态系统服务功能，即物质生产能力、调节空气、涵养水源、土壤保护及旅游文化，研究该区域2005、2009、2035年3个时间点只开采及边开采边复垦两种不同情景下矿区生态系统服务功能价值，结果表明：边开采边复垦下的生态服务价值远远大于只开采而不采取任何生态重建措施下的生态服务价值，即土地复垦有效地提高了矿区的生态系统服务价值。
