摘要： 本文对滇产樟科植物22属，209种进行了属、种分布区类型的划分。属的分布区类型可划分为：全热带分布，热带美洲和热带亚洲间断分布，热带亚洲分布，东亚北美间断分布，以及中国特有5个类型，并结合滇产原始种类对相关属的起源发生进行了讨论，对各属在云南境内各区的种数进行了统计。种的分布区类型可划分为：热带美洲分布，旧世界热带分布，热带亚洲分布，地中海分布，东亚分布，以及中国特有分布6个类型。对滇产209种在各类型及在各区的统计发现滇东南樟科植物种类极为丰富，其原因是历史成因造成，并推断该地区是樟科植物的起源地之一或为其一部分。并且认为云南同四川、西藏、海南、广东、广西在樟科植物区系上是密切相近的。长江以南由于地质历史上较为稳定，而成为樟科植物在其起源之后的扩散地。

Abstract: From the study of the geographical distribution of Lauraceous 22 genera and 209 species in Yunnan Province, the distribution-patterns of genera and species are discussed. The distribution-patterns of genera are divided: Pantropic, Tropical Asia, Eastern Asia-North America, Tropical America and Tropical Asia, as well as Endemic in China. From the analysis of the primitive forms in Yunnan Province, the author discussed the origin of related genera. Furthermore, the author also counted up the number of Lauraceous plants for each genus in relation to the floristic regionalization in Yunnan Province. The distribution-patterns of spe-cies are divided: Tropical America, Old World Tropic, Tropical Asia, Mediterranean, Eastern Asia and Endemic in China. From the analysis of the distribution-patterns of 209 species in Yunnan Province, it was found that SE Yunnan is of great abandance in endemic species.
