摘要
土壤大孔隙可导致优先流从而引起地下水污染,植物根孔属于土壤大孔隙的一类,它在导致优先流引起的地下水污染方面有特殊的作用。本文从土壤大孔隙的角度出发,综述了根孔有别于其他类型大孔隙的特性及其特殊的生态功能,一方面为更好的研究土壤大孔隙提供参考因素,另一方面为解决与土壤和地下水污染有关的环境问题提供新的思路。
The soil macropore could contain some preferential flow, which would lead to groundwater pollution. The root channel of plant is one kind of soil macropore and has a special function in the groundwater pollution. The paper summarized the features and ecological function of plant root channel, which differs from the soil macropore of other types. The research on plant root channel would be able to offer some references for better understanding of soil macropore and to provide a new idea of solving environmental problem related to soil and groundwater.
