煤矿区生态累积效应评价研究进展

煤炭开采活动的特点决定了其对矿区生态环境的影响具有明显的累积效应。在梳理生态累积效应概念和特征的基础上,结合煤矿区各类活动的特点综述了煤矿区生态累积效应的影响源、途径、效应及类型,并评述了目前国内外有关煤矿区生态累积效应的相关研究。目前针对煤矿区生态累积效应的研究仍十分有限,评价方法也尚不成熟。关于煤矿区的生态累积效应研究主要集中在效应评价方面,有关生态累积效应的发生机理、指标体系构建、评价方法学、管理规划及应对机制,是未来应加强的重点研究领域。

A Review on Evaluation of Ecological Cumulative Effect in Coal Mining Areas

Coal mining activities usually make significantly cumulative effect on the ecosystem and local environment in mining area. In this study, the concept and characteristics of ecological cumulative effects (ECEs) of coal mining activities were summarized. Furthermore, the sources, pathways, effects, and types of ECEs of coal mining activities were reviewed and identified with considering the characteristics of various coal mining activities in coal mine areas, based on the studies focusing on ECEs of coal mining activities worldwide. This review found that most of the published literatures were focused on assessing the effects of coal mining activities in a specific area instead of ecological cumulative effects, and the methodology for the assessment of ECEs was not well established. Future studies are suggested to focus on the occurrence mechanisms of ECEs, selection of assessment indices, assessment methodology, and management strategies.
