太行山龙泉关地区植被类型的研究

太行山龙泉关地处北纬38°50′,东经113°50′,海拔高度700-2280米,山区地形复杂。植物种类较丰富,记录野生高等植物共294种,隶属于71科,180属。其中乔木29种,灌木31种,草本234种。种子植物属的地理成分有15种分布区类型,其中北温带分布最多,占48％以上,热带分布共占18.3％,中国特有分布占1.4％。该地区地带性植被类型有寒温性针叶林、温性针叶林、落叶阔叶林、落叶阔叶灌丛、灌草丛、草原,非地带性植被类型有草甸。 太行山龙泉关地处北纬38°50′,东经113°50′,海拔高度700-2280米。按吴氏植物区系分区系统,太行山植物区系属泛北极植物区,中国-日本森林植物亚区,华北地区,华北平原、山地亚地区。至今,无人对该段山区进行地植物学方面的研究。1985年,我们对该段山区的植被类型进行研究,目的为开发利用太行山植被资源,开展山地生态系统的研究,维护山地生态平衡提供地植物学方面的依据。
