摘　　要：【目的】调查浙江省庆云县范围内楠属Phoebe植物野生资源,以期为楠木合理保护与开发利用提供理论支撑。【方法】采用样方法每木检尺对庆元县域范围的野生楠木野生资源进行全面调查,掌握其分布数量、分布格局、生境及居群状况。【结果】庆元县域楠属植物有浙江楠P.chekiangensis、闽楠P.bournei、紫楠P.sheareri等3种,分布点23个,覆盖9个乡镇街道。浙江楠和闽楠多分布于800 m以下,紫楠水平分布跨度最大,垂直分布可达1250 m,但种群植株数量少。现有居群多存于村旁风水林或人为干扰较少的保护区,楠木群落主要建群种和优势种为壳斗科Fagaceae和樟科Lauraceae树种。【结论】庆云县楠木野生资源稀少,亟需保护,人为活动频繁及楠木自身光需求特性是导致濒危的主要成因。[Objective]This study is aimed to better utilize and preserve the wild resources of Nanmu(Phoebe).[Method]With the employment of tally and quadrat method,an investigation was conducted of the distribution,habitation and population of Phoebe species in Qingyuan County of Zhejiang Province.[Result]P.chekiangensis,P.bournei,and P.sheareri were found in Qingyuan County with a total of 23 distribution areas detected covering streets in nine townships.P.chekiangensis and P.bournei were mostly distributed below the altitude of 800 meters whereas P.sheareri enjoyed the largest horizontal distribution span with the altitude possibly reaching up to 1250 meters,but a relatively small population size.The wild resources of Phoebe in the counties are scarce with most populations located either in fengshui woods or protected areas with Fagaceae and Lauraceae as the main dominant and constructive species.[Conclusion]The endangerment of Nanmu mainly attribute to frequent human activities and their unique demand of light.
