摘　　要：利用粉煤灰和酒糟的理化特性,将二者按照一定比例配成混合基质,通过白花三叶草的盆栽试验,分析种植前后混合基质的理化特性及三叶草的生长情况,并检测基质和植株中的重金属含量。结果表明:当粉煤灰与酒糟的质量比为4∶1时,基质最适合三叶草的生长,而且基质和植株体内的重金属含量均未超出国家标准。因此,可以将该基质作为矿区塌陷地的复垦基质。According to their physical and chemical properties, fly ash and lees are mixed into a substrate in certain proportion and used in the pot experiment of white clover （ Trifoliurn repens）. The physical and chemical properties of the mixture substrate before and after the planting and the growth of white clover are analyzed and the heavy metal content of the substrate and the white clover are measured. The results show that the substrate with a fly-ash to lees ratio of 4：1 is the most suitable for the growth of white clover and the heavy metal content of the substrate and the white clover doesnt exceed that specified in the national standard. Therefore, this substrate can be used for the land reclamation in the subsidence mine area.
