摘要
包气带粘性土的特性及其分布规律是影响污染物自然衰减的重要因素。在分析粘性土类型和粘性土防污机理的基础上,探讨了微生物等因素对粘性土防污效果的影响,指出目前包气带粘性土防污研究中存在的若干问题。3S技术、ADM非确定理论有助于解决研究尺度偏小、量化指标不足的问题,多学科交叉复合将是包气带粘性土层防污研究的必然发展趋势。
The characters of cohesionless soil and its spatial distribution regularities are the key factors to the natural attenuation of contaminant.On the basis of analyzing types of clay soil and antifouling property,the effects on antifouling effect of clay soil were discussed,and the existing problems of antifouling property of clay soil were put forward.3S and ADM system were useful to solve the problem of the smaller scale and index quantification,and it points out that it was a hopeful research direction to the interdisciplinary studies.
