摘　　要：本文对罗浮山植物区系与邻近地区植物区系作了比较分析，通过相似性指标以及计算机聚类分析的方法探讨罗浮山与邻近地区的区系关系．统计分析表明，罗浮山与鼎湖山联系较密切，与尖峰岭的相似性也很高，而与庐山的植物区系关系较少．he Luofushan mountain in Guangdong Province is located at 23°15′-23°22′N and 113°57′-114°4′E. It is of mild climate all the year, abundant rainfall and various plant species. On the mountain 1168 speCies of vascular plants (including varieties and cultured plants) have been identified, in which there are 676 genera in 201 families. A comparative study of the floristics relationships betWeen the Luofushan mountain and its adjacent restons is made with computer cluster analysis in which the similarity index is used . The result indicates that the flora of the Luofushan mountain is the most similar to that of the Dinghushan in mid-west Guangdong, the Percentages of common family, genera and species are 97. 4 %, 94. 7%,, 82. 3 % respectively. It is also similar to those of the Jianfengling in Hainan Island, Cheboling in North Guangdong and Yinnashan in East Guangdong, Its family, genera and species common to those of the Jianfengling are 88. 0%, 67. 3% and 37. 5% to those of the chebaling are 87. 2%, 67. 1 % and46. 5% 1 and to those of the Yinnashan are 87. 2% , 56. 4 % and 40. 8% respectively. But itsrelationship to the flora of the Lushan in Jiangxi Province is not so close. The common family,genera and spotes account for 77. 8 %, 57. 4 % and 30. 6% respectively.
