摘　　要：保护生物多样性不仅是国家战略,已上升为全球使命,而生物多样性保护离不开珍稀濒危植物的保护利用。楠木类树种为亚热带和热带树种,是组成常绿阔叶林的主要树种,亦是驰名中外的珍贵用材树种,以中国资源最为丰富。由于历代砍伐利用,致使这一丰富的森林资源近于枯竭,此类树种多数被列为珍贵树种和濒危植物,是典型的代表性珍稀濒危类树种。本文围绕楠木类树种,对其文化、生物学特性、资源现状、保护培育以及在园林绿化中的开发应用进行了总结归纳,并就其资源保护未来重点研究方向及在城市绿化中应用的机遇和挑战进行了阐述,以期对其更好地保护和挖掘利用,进一步做好其资源的保护和保育研究,推动楠木类珍贵树种在上海及其他地区的绿化应用,极力提高城市生物多样性。Protecting biodiversity is not only a national strategy,but also a global mission.Biodiversity protection cannot be separated from the protection and utilization of rare and endangered plants.The most precious“Nanmu”tree species are subtropical and tropical species,serving as the primary tree species in evergreen broad-leaf forests.They are also well-known precious timber species both domestically and internationally,with China having the most abundant resources.Due to historical logging and utilization,this rich forest resource has been almost depleted.Kinds of these tree species have been listed as the national key protected plants and are typical representative rare and endangered tree species.This article comprehensively summarized their cultural connotation,natural resources,conservation status,and the development and utilization in landscaping.It also elaborated on the future key research on resource protection and the opportunities and challenges of its application in urban greening,in order to better protect and utilize them,and promote the conservation of these tree species and their ex situ protection in Shanghai and other cities,contributing to urban biodiversity conservation.
