摘要
收集了中国32个省市区壳斗科植物属与种的数据,探讨了中国壳斗科植物空间分布规律,并利用Jaccard相似性系数,来揭示全国各省市区之间的密切关系。研究结果表明:壳斗科植物在中国的分布很广,属与种的分布均由西南至华南、再向北依次减少,其中栎属种的分布遍及全国(除新疆),其余属种的分布集中分布于气候类型为亚热带和热带的南方地区。从属的相似性系数聚类水平上看,可以将中国壳斗科植物分布划分为3个区:北方少数区、南方丰富区和新疆孤立区;从种的相似性系数聚类水平上看,可以将中国壳斗科植物分布划分为5个区,各分区是地理上相近、气候类型基本一致的地区。
This paper explored the spatial distribution of Fagaceae flora in Chinaby coffectmgtne aata of genus and species of Fagaceae flora from 32 provinces in China, and used the Jaccard similarity coefficient to reveal the close relationship among provinces and regions all over the country. The results showed that the distribution of Fagaceae flora was very Widein China, with distribution of genus and species reducing gradually from southwest to South Chinaand then to north in which the genus quercus was widespread throughout the country （except Xinjiang）. The rest of genus and species was centrally distributed in southern China region of which climate belongs to subtropical and tropical- types. From the level of dendrogram of similarity coefficient of genus, Chings distribution of Fagaceae flora can be di- vided into three areas： the northern minority region, southern rich region and Xinjiang isolated region. From the level of dendrogram of similarity coefficient of species, China＇s distribution of Fagaceae flora could be divided into five areas, each areas was geographically close and basically consistent with climate type.
