摘要
浮戏山有种子植物９６科３１３属５５２种，区系成分以北温带、泛热带和旧世界温带三种成分为主，其次是东亚和东亚北美间断成分，植物区系具有明显的温带性质。以植物地理成分为指标，将浮戏山和全国其它１９个地区进行系统聚类分析，结果表明，浮戏山植物区系成分和与其同处于中纬度地区的河南境内的桐柏山、大别山、小秦岭、老君山及山西中条山、山东泰山最为相似，而与高纬度地区的长白山，低纬度地区的广西大瑶山和海南五指山最为疏远。结果还表明，在一定经度范围内，两个地区之间植物区系成分的亲缘关系与其所处的纬度相关；纬度相近，其亲缘关系也相近；
Mount Fuxi is located in the Central Henan Province. It is rich in spermatophyte 96 families,317 genera,556 species.From a point of view of geography-distribution elements,all the genera are divided into 15 distributional types. It is mainly characterized by the NorthTemperate Genera(31.1%),the Pantropical Genera (17.9%) andthe old World Temperate Genera(13.2%). It is second characterized by the Eastern Asia genera(11.4%) and the Eastern Asia-North America Genera(9.2%). The percentage of all above genera is 82.8%.The floristic relationship among different regionsin China werecompared by using system cluster analysis. The result showed that:the resemblance degree between two regions depends on their latitudes in the certain longitudes.
