摘　　要：对煤矸石山进行绿化是其处置与利用的有效途径，选择湿润地区淮南潘一矿煤矸石山作为研究对象，通过取样和室内测试分析，揭示了其理化特性。结果表明：该煤矸石山风化程度有限，70％左右的石砾或石块的粒径大干1mm，30％～40％的粒径大于3mm；pH值较高，碱性较强；除了有机质含量高于对照的农田外，其余营养元素都较为缺乏，尤其是速效养分缺乏；重金属含量远低于土壤环境质量二级标准，不存在重金属污染。因此，采取适当的基质改良和种植技术，就可实现该煤矸石山的绿化。The afforestation on the coal rejects dumping hill is an effective access to dispose and utilizate the coal rejects. The coal rejects dumping hill of Panji No. 1 mine in sub - humid areas, Huainan has been chosen, with the sampling and indoor test and analysis, the physical and chemical properties have been revealed. The result showed that weathering degree of this rejects hill was still limited, about 70% of the coal rejects diameters were greater than 1 mm, 30% -40% of the diameters of the gravel or stones were larger than 3 mm; pH values were comparatively high and alkalescence was comparatively strong; Besides that the organic matter content was higher than that of the contrast farmland, others were all comparatively deficient, especially available nutrients ; the heavy metal content is far lower than the secondary standard of soil environmental quality, the coal gangue had no heavy metal pollution. Consequently, the coal rejects dump could be planted if appropriate matrix improvement measures and planting technique could be taken.
