煤炭去产能对矿区生态环境的影响研究

摘要

China's coal production began to decline in 2014,ending a 14-year growth in the situation.In this context,Chinese government implemented policy of cutting overcapacity,closing great amount mines with backward production capacity,integrating a large number of small and medium-sized mines,which laid the foundation for the sustainable development of new normal coal industry,but the impact of this policy on ecological environment of mining area attracted rare attention.Based on SPOT5/ZY-3 high-resolution remote sensing images in September 2008,December 2010 and December 2015,by remote sensing (RS) and geographic information system (GIS),taking Peibei coal mine of Xuzhou as an example,establishing the evaluation model to evaluate the ecological environment quality in 2008,2010,2015,then compared with the coal production in this mining area.The results show that coal production can improve the ecological environment of mining area,and the coal production is negatively correlated with the change of ecological environment.%2014年我国煤炭产量开始下降,结束了连续14年增长的局面.国家随之实施煤炭产业去产能政策,关闭了大量落后产能矿井,整合了大量中小型矿山,为煤炭产业新常态可持续发展奠定了基础,但是这一政策对矿区生态环境的影响目前还鲜有关注.为此,以江苏省徐州市沛北矿区为例,基于2008年11月、2010年12月和2015年12月的3景SPOT5/资源三号高分辨率遥感影像,采用遥感技术(RS)和地理信息系统技术(GIS),利用建立的评价模型,评价了该矿区2008年、2010年、2015年的生态环境质量,然后将之与该矿区煤炭产量状况进行对比分析.分析表明,煤炭去产能对矿区生态环境有改善作用,煤炭产量变化与生态环境变化呈负相关关系.
