藓类生物结皮的生态适应及在石漠化修复中的作用研究

Ecological Adaptation and Restoration of Moss Biological Crusts in Rocky Desertification

喀斯特石漠化是土地荒漠化的主要类型之一,而中国西南的石漠化又是石漠化最严重的地区,其治理和恢复的难度是世界之最,这对石漠化地区生态环境的可持续发展造成了严重影响。通过野外考察和查阅文献,总结了藓类生物结皮的形态结构、持水能力、生理适应,并阐述了其在石漠化修复中的作用。

Karst rocky desertification is one of the main types of land desertification, which it is the most seri-ous rocky desertification area in southwest China. However, it is extremely difficult to deal with the environ-mental problems in karst regions and hard to recover and govern if once deteriorated. Consequently, rock de-sertification has been severely restricted the sustained development in this areas. By collecting literature and experience of field investigation, we summarized the structure, water holding capacity and physiological ad-aptation of moss biological crusts and its ecological restoration in controlling rocky desertification.
