Karst regions in southwest China are facing serious ecological problems, among which rocky desertification is the most serious one that is urgent to be controlled by more efficient and sustainable ways. We summarized the stress resistance of bryophyte, and the positive effects of bryophyte soil crust on soil stability, soil erosion resistance, soil organic matter content, soil nutrient status, water infiltration and evaporation, the redistribution pattern of precipitation in soil, the reproduction and survival of soil creatures, and the succession of vegetation and biodiversity in karst rocky desertification ecosystem. In those regions, bryophyte soil crust played irreplaceable roles in soil, hydrological and biological processes. The successful practices in desertification regions of north China indicated that artificially cultivated bryophyte soil crust had several advantages, including low cost and high compatibility with environment. In conclusion, artificial cultivation of bryophyte soil crust could be an important supplement to the current comprehensive control measures and will play an important role on the control of karst rocky desertification.
中国西南喀斯特地区正面临着严重的生态问题，其中石漠化最为严重，亟待采用更高效、可持续的方式加以治理。我们总结了苔藓植物的抗逆性，以及苔藓植物土壤结皮对土壤稳定性、抗土壤侵蚀能力、土壤有机质含量、土壤养分状况、水分入渗与蒸发、土壤中降水再分配模式、土壤生物繁殖与存活，以及喀斯特石漠化生态系统中植被演替和生物多样性的积极影响。在这些地区，苔藓植物土壤结皮在土壤、水文和生物过程中发挥着不可替代的作用。中国北方荒漠化地区的成功实践表明，人工培育苔藓植物土壤结皮具有成本低、与环境兼容性高等诸多优点。总之，人工培育苔藓植物土壤结皮可为当前的综合防治措施提供重要补充，并将在喀斯特石漠化治理中发挥重要作用。
