中文摘要	通过对寒旱区生态修复技术的集成创新,结合寒区露天煤矿排土场植物生长条件特点,提出了适合矿区边坡的生态修复技术.选择典型煤矿排土场展开现场试验,观测人工种植植物的生长情况,并采用计算流体力学数值分析手段,对排土场边坡生态修复防止风力侵蚀和降雨冲刷的效果进行了分析.结果表明:采用边坡穴植植物装置实施的排土场生态修复工程效果良好,施工1 a后其边坡植被覆盖度达到95%,且边坡植物群落较为稳定,有效地消除了该地区冬季的风力侵蚀和夏季的降雨冲刷,彻底解决了排土场的水土流失问题.
英文摘要	Aimed at ecological restoration technology integration and innovation in cold and arid regions, combining with the characteristics of plant growth in cold and opencast coal mine, a suitable technique of slope ecological restoration in mining areas has been put forward. The functions of ecological restoration on mine dumps for prevent wind erosion and rainfall erosion are studied by field experiment in typical coal mine, observing the growth situation of artificial plant and using numerical analysis method of computational fluid dynamics. The results show that the hole-planting on slopes has excellent ecological restoration engineering effect; the slope vegetation coverage reaches 95% after one year’s construction, and the slope plant community is more stable, which effectively eliminate the wind erosion in winter and rainfall erosion in summer; the problems of soil and water loss, therefore, has been solved thoroughly in the region.
