荒漠化地区生物结皮的研究进展

Advances of Bio-Crust Research in Desertification-Prone Areas

防沙、治沙和固沙一直以来是荒漠化生态环境建设的热点问题。作者从生物结皮对荒漠化地区生态环境的影响,以及在生态系统演替中起到的重要作用等方面进行了综述,指出了地衣在生物结皮中所占有的重要地位,展望了生物结皮研究与应用的前景。

The job of sand-protecting, sand-controling and sand-fixing is the most important research forefront in ecological environment. This paper focuses on the concept of crusts, the influence of hydrological distribution and soil characteristics. It points out that bio-crust plays an important role in ecological condition and succession of desert ecological system and lichen crust is quite useful and widespread in the desert regions. Some preliminary suggestions are further given for understanding more the relationship between bio-crust ecosystem and the prospect in future research about desertitication-prone areas.
