| 摘要: |
| 木兰科(Magnoliaceae)植物作为被子植物中现存较为原始的类群，在被子植物起源、发育和进化研究中具有重要的科学价值。广西木兰科植物资源十分丰富，包含8属43种，且拥有多种珍稀特有植物。本文系统综述了广西木兰科植物的物种分布、生境特征、系统分类、光合生理、遗传多样性及繁育技术等方面的研究进展，认为其分布受地形和气候的显著影响，且不同物种在遗传结构与环境适应性上存在差异。目前，广西木兰科植物面临着栖息地破碎化与人为干扰加剧的双重威胁，部分特有、濒危物种的研究与繁育利用尚不充分。基于此，本文提出了加强广西木兰科植物资源监测、深化环境适应性与抗逆机制研究、推动属种间的系统比较分析、构建多维综合研究框架等建议，旨在为广西木兰科植物的资源保护和可持续利用提供科学依据。 |

| Abstract: |
| Magnoliaceae,as a primitive family among extant angiosperms,holds significant scientific value for studies on the origin,development,and evolution of angiosperms.Guangxi is particularly rich in Magnoliaceae resources,harboring 43 species belonging to 8 genera,which include many rare and endemic taxa.This review provides a comprehensive overview of the research progress in the species distribution,habitat characteristics,taxonomic systems,photosynthetic physiology,genetic diversity,and reproductive techniques of Magnoliaceae in Guangxi.It highlights that species distribution is significantly influenced by topography and climate,and different species exhibit distinct adaptive traits and genetic structures.However,plants of this family in Guangxi currently face considerable threats such as habitat fragmentation and intense human disturbances,with insufficient studies on the propagation and utilization of some endemic and endangered species.On the basis of the current research,suggestions including strengthening resource monitoring,expanding research on environmental adaptation and stress resistance mechanisms,promoting systematic comparative analyses across genera and species,and establishing a multidimensional integrated research framework are proposed,aiming to provide a scientific basis for the conservation and sustainable use of Magnoliaceae resources in Guangxi. |
