摘要
研究目的:分析不同地域矿区煤炭开采引起的生态效应及其地域分异现象,为差异性土地复垦与生态重建技术提供依据。研究方法:综述法、实地调查法和比较研究法。研究结果:煤炭开采扰动生态系统要素,改变生态系统结构和功能,其生态效应明显;这种效应在矿区内和矿区间表现程度和形式不尽相同,存在分异现象;影响生态效应差异的主要因素是采矿扰动因子和本底生态条件。研究结论:开展矿区生态监测和修复需要分区对待,并探索其敏感性指标或建立综合性指标评价体系。
The purpose of this paper is to analyze the ecological impacts of coal mining and the regional differentiation to provide evidence for differentiated technologies of land reclamation and ecological rehabilitation. Methods employed include literature comprehensive analysis, field survey and comparative research. The results show that the mining activities disrupt the ecosystem with sharp ecological effects. In different mining area or different places in intra-mining area, the effects vary in degree and mode. The main factors that cause the differentiation are mining disturbance and background ecological conditions. Therefore, it is essential to have differential treatment while dealing with ecological monitoring and restoration in different mining areas.
