摘　　要：Mycorrhizal mulberry is a plant, whose mulberry root and Arbuscular Myc-orrhizal fungi came into being a symbiotic relationship by a mean of natural or artifi-cial inoculation. Mycorrhizal mulberry coupling with main ecological barriers, such as barren soil drought in rocky desertification area, wil be beneficial to recovering the karst degraded ecosystem by removing these stresses. So, mycorrhizal mulberry is considered a new effective way in ecological control of karst rocky desertification. The research summarized the structures and the characteristic eco-physiological functions of arbuscular mycorrhizal fungi （AMF）, and preliminarily discussed its availability and research in karst rocky desertification restoration ,including investiga-tion of AMF diversity, the key affecting factor of AMF species diversity, the sym-biosis mechanism between AMF and mulberry, promoting the development of agri-cultural economy in Karst Rocky Desertification area by mycorrhizal mulberry. These elaborate efforts are to demonstrate mycorrhizal mulberry adapting to karst environ-ment from a new view, lay a theoretical basis for karst degraded-ecosystem restoration, and final y guarantee sustainable development of mycorrhizal mulberry in rocky desertification area.菌根桑能与石漠化地区贫瘠、干旱等主要生态障碍相耦合,有利于减轻贫瘠干旱胁迫,成为喀斯特石漠化生态治理的一种新的有效措施。在综述丛枝菌根真菌的结构、生理生态功能的基础上,初步探讨了石漠化恢复过程中菌根桑的可利用性以及在调查桑树根系丛枝菌根真菌多样性、影响丛枝菌根真菌多样性的关键因子、筛选优良抗性菌株、丛枝菌根真菌与喀斯特石漠化地区桑树的共生机制等几个方面开展前期研究工作,旨在从全新的角度探讨菌根桑对喀斯特生境的适应对策以及为岩溶生态系统退化与恢复机理奠定基础,从而保证菌根桑在石漠化地区的可持续发展。
