摘　　要： 对广东茂名页岩油工业固体废物堆置场中裸露的灰渣及植林 15年的试验区土壤的理化性质进行系统分析与比较 ,结果表明 :通过以人工营林为主的合理修复措施 ,在良性生物循环作用下 ,已使灰渣向新成土演化 ,土壤达到一定肥力水平 ,酸度得以调节 ,基质保水保肥能力加强 ,植物体内元素含量正常 .由此构建了良好的人工生态系统 ,并使系统内部及其与外界的物质与能量流动过程得到调节与优化 ,使整体环境得到整治 . Systematic analyses and comparison have been conducted to study the properties of the bare spent oil shale and the soil developed on the 15\|year experimental forestation field located in the solid waste dumping area of Maoming, Guangdong Province. The results reveal that reasonable remediation with forestation as the main measure has led to benign biological cycle of the elements. In this way, the spent oil shale has evolved into entisol with a certain level of fertility, the acidity may be adjusted, the capacity to conserve water and nutrients by the matrix has been strengthened, and normal elemental contents in the plants have been maintained. The benign ecosystem has been constructed with the adjustment and optimization of internal and external material and energy flows so that the environment has been remediated to a certain extent.
