凉水与帽儿山自然保护区植物区系的比较研究

通过凉水红松阔叶次生林与帽儿山红松阔叶次生林的区系成分对比分析,阐明了凉水自然保护区与帽儿山自然保护区的区系成分的差异及其影响差异的因素。结果表明,纬度差异是两个自然保护区区系成分差异的重要因素,凉水自然保护区纬度偏高,温带成分占有很大比例,而帽儿山自然保护区纬度偏低,增加了许多华北植物区系成分及热带、亚热带植物区系成分。凉水自然保护区共有种子植物80科243属441种,帽儿山自然保护区共有种子植物87科328属750种。在特有成分上,两个保护区也有差异,帽儿山自然保护区含有更多的中国特有种。

Comparison on Floristic Components between Liangshui Nature Reserve and Maoershan Nature Reserve

The comparison analysis on floristic components of Korean pine broad-leaved secondary forest in Liangshui Nature Reserve and Maoershan Nature Reserve illustrated the difference of floristic components and the influencing factor between two nature reserves.The results showed that the latitude difference was an important factor of the floristic components difference in both areas.The latitude of Liangshui Nature Reserve was on the high side and the temperate composition occupied very large proportion.However,the latitude of Maoershan Nature Reserve was on the low side and it added a lot of floristic composition of North China and tropical,subtropical floristic composition.There were 80 family,243 genus and 441 species in Liangshui Nature Reserve,and there were 87 families,328 genus and 750 species in Maoershan Nature Reserve.In the peculiar composition,there were differences between the two nature reserves,where Maoershan Nature Reserve had more Chinese endemic species.
