生物土壤结皮的研究进展

The Research of Biological Soil Crust

生物土壤结皮存在于沙漠化的土壤中,是荒漠地区最具特色的景观之一。综述了近年来干旱半干旱荒漠地区生物土壤结皮的组成和分布,重点介绍了生物土壤结皮的生态作用以及在退化生态系统植被恢复与重建中的作用,并对其研究前景进行了展望,这对进一步探明生物土壤结皮的生态作用具有重要的理论和实践意义。

Biological soil crust exists in the soil of desertification and are one of the most unique desert landscapes of the region.Composition and distribution of biological soil crust in the arid and semi-arid desert region in recent years are summarized and the ecological role of biological soil crusts and the role of recovery and reconstruction in degraded ecosystems are explained in this paper.The research progress is put forward for important theoretical and practical meanings of ecological role of soil crust.
