摘　　要：通过对280自燃煤矸石山的调查研究和试验测试,分析得出影响自燃煤矸石山植被构建的限制因素有14个,包括:干旱、积水、高温、低温和高温同时胁迫、盐害、酸害、压实、养分、水土流失、污染气体、重金属、扬尘、陡坡、地形破碎。其中,干旱、高温、盐害、酸害、压实、养分缺乏和水土流失是最重要的影响因子;高温是影响植物成活的主要因素;这些因子单一或交互于植物,对植物生存生长产生影响。研究结果对于自燃煤矸石山植被恢复、生态重建和煤矿区生态环境改善具有重要意义。With the investigation study and the test and measurement on the 280 Spontaneous Combustion Coal Rejects Hill, the paper an- alyzed the 14 factors limited to the vegetation restoration of the spontaneous combustion coal rejects hills. The 14 factors were including the drought, ponding, high temperature, low temperature and high temperature joint, salty disaster, acid disaster, compacting, soil nutrient, water and soil loss, polluted air, heavy metal, dusting, steep slope and topography broken. Among them, the drought, high temperature, salty disaster, acid disaster, compacting, soil nutrient and water and soil loss were the most important influence factors. The high temper- ature would be the main factor affected to the growth of the plants. Those factors would be individually or multi affected to the plants and would have the influences to the growth of the plants. The study results would have the significance of the spontaneous combusted coal re- jects hill restoration and the ecological reconstruction and the ecological environment improvement of the mine area.
