嵩山与鸡公山、天目山种子植物区系比较

Comparison of Seed Plant Flora of Song Mountain,Tianmu Mountain and Jigong Mountain in Henan

摘要: 利用前期研究成果和最新植物区系研究资料,对嵩山与鸡公山、天目山的种子植物区系进行了比较研究,计算了相似性系数.结果发现嵩山与鸡公山、天目山的种子植物区系存在一定的差异:嵩山以温带成分为主,与华北植物区系联系密切;鸡公山和天目山的温带分布类型虽占有一定的地位,但热带成分丰富,过渡特点明显,加强了与华中、华东植物区系的联系;嵩山与鸡公山、天目山植物区系的相似性表现在:温带成分都占有一定的优势,支持了落叶阔叶林仍然是河南暖温带地区相对稳定的森林植被类型的观点.

Abstract: The Song Mountain,Jigong Mountain and Tianmu Mountain,situated in the middle and south parts of Henan province in China.On basis of comparison research carried out for the flora of Song,Jigong and Tianmu Mountain,we make use of a mathematic model to calculate comparability coefficient.Study result shows that there exists some difference between the flora of Song Mountain and that of Jigong Mountain and Tianmu Mountain.Song Mountain gives first place to temperate zone component closely related to that in Nor...
