| 摘 要： | 从物理、化学、生物三个方面分析了人工湿地堵塞的机理,指出湿地堵塞的过程实质上就是有效孔隙率减少的过程,湿地的堵塞与否,堵塞的程度如何,可由其饱和水力传导系数来表征。对几个与人工湿地堵塞有关的数学模型作了介绍和分析,并探讨了一些预防人工湿地堵塞的措施以及其未来的研究方向。

| Abstract: | This paper briefly reviewed the physical,chemical and biological causes of clogging in constructed wetlands with subsurface flow,indicating that clogging was virtually caused by the decrease in substrate effective porosity and that values of saturated hydraulic conductivity of the substrate could be used to evaluate clogging status.Some models related to clogging as well as solutions to clogging problems were enumerated. |

| Keywords: | constructed wetlands clogging saturated hydraulic conductivity effective porosity modelling |
