中文摘要：

菌根真菌是土壤中重要生物成员之一,不仅具有丰富的遗传多样性和物种多样性,其功能也是丰富多样,主要体现在：1）影响陆生植物起源、进化、演化与分布;2）促进植物的生长发育;3）提高植物的抗逆性;4）修复污染与退化土壤、改善土壤质量与健康状况;5）促进农林牧业的生产;6）保持生态平衡、稳定生态系统及其可持续生产力.随着技术发展和研究的深入,菌根真菌新功能将会不断被发现.

英文摘要：

Mycorrhizal fungi are an important member of soil microorganisms, not only rich in genetic diversity and species diversity, but also in functional diversity, which mainly manifest in： 1） affecting the origin, evolution, and distribution of terrestrial plants, 2） promoting plant growth and development, 3） enhancing plant tolerance against environmental stress, 4） remedying polluted and degraded soils, 5） promoting agricultural, forestry, and animal husbandry production, and 6） maintaining ecological equilibrium and stabilizing ecosystem and its sustainable productivity. With the development of technique and research, more functions contributed by mycorrhizal fungi would be discovered.
