摘　　要：鉴于废弃物堆积引起的环境恶化和水土流失、矿山开采等导致土地退化,利用废弃物改良土壤、修复生态环境的研究和技术推广便具有十分重要的意义。文章介绍了粉煤灰与若干有机固体废弃物的理化特性,分析了其单一施用改土的弊病,重点阐述了粉煤灰与有机固体废弃物配施对土壤理化生性质的影响。认为粉煤灰与若干有机固体废弃物配施具有良好的土壤改良效果,也是我国固体废弃物处置和利用的最佳途径之一。此外,分析了有关废弃物配施改土中有待进一步解决的问题,并提出了今后工作的若干建议。Because of the serious environmental degeneration due to the accumulation of various solid wastes, soil erosion and mining activities, it is very important to study the soil improvement and environmental renovation by utilizing solid wastes as soil additives. In this paper, the properties of fly ash and some biosolids and the shortages of their separate use as soil additive are discussed. The influences of mixtures of fly ash and biosolids on the qualifies of soil and the growth of plants are particularly analyzed. The utilization of mixtures of fly ash and biosolids in soil amendment is suggested to be one of the best methods of solid waste disposal and utilization. Some suggestions on further studies of the utilization of solid waste mixtures in soil amendment are also given.
