摘要 微生物结皮与土壤水文过程的关系一直是微生物结皮研究中最具争议性的热点问题。文章对国内外这一领域的研究进展进行了综述,系统地介绍了微生物结皮在降雨入渗、水分保持和土面蒸发等土壤水文过程中的功能,总结了微生物结皮土壤水文学研究中的各种观点,针对不同观点之间产生的争议,作者认为微生物结皮的时空特殊性、复杂性以及研究手段和方法的多样性是产生争议的主要原因。最后,从试验方法和研究目标上对该研究领域进行了展望。 The relationship between microbiotic crust and soil hydrology has been being the most disputed hotspot in the microbiotic soil crust research field. This paper reviewed the advances of domestic and overseas studies on the influence of microbiotic crust on soil hydrology, including soil-water infiltration, soil-water conservation and soil-water evaporation. The contradictory research conclusions and their disputed causes were synthetically analyzed. It was considered that the space-time particularity, complexity of microbiotic crusts and the diversity of studying methods are the principal causes of the contradictory results.
