论黄山松林在庐山植被垂直带谱中的位置

ON THE POSITIONAL PROBLEM OF THE PINUS TAIWA ANENSIS FOREST IN THE VEGETATION ALTITUDE BELTS OF MT.LUSHAN

黄山松林是我国东部亚热带中山地区垂直带上特有的山地温性针叶林,垂直分布高度从梅拔600～700m以上的山坡、山脊。上限可分布到1750～1900m左右的山顶。庐山的黄山松林主要分布在海拔800～850M以上至山顶的地段。本文通过对庐山黄山松林的生境、区系性质、生活型谱、以及群落动态和残存群落的分析,有关孢粉资料的考证和与周围山地的对比,认为黄山松林是温性针叶林。尽管目前由于人为活动而使之成为庐山海拔1000m以上地区现存植被的优势类型,但在植被垂直带划分中它应从属于山地落叶阔叶林带。

The Pinus taiwanensis forest is a kind of temperate coniferous forestfound only in the vertical distribution of the mountain vegetation in thesubtropical area of East China. It appears on mountain Slopes and rid-ges, from elevations of about 600-700m with upper limit of about 1750-1900m on mountain peaks its vertical distribution range is from 800-850m above sea level to the peak. This paper deals mainly with the po-sition of this pine forest in vegetation altitude belts of Mt. Lushan, Having analysed the habitats, flora, life form spectrum, and the sy-ndynamic of the forest, as well as the clastotype of broadleaved forest,studied some relative materials of pollen analysis and compared Mt. Lu-shan with neighbouring mountains, we regard the Pinus taiwanensis forestas temperate coniferous forest although the anthropogenic influences areso powerful that it now becomes the dominant vegetation of Mt. Lushanat elevation of about 1000m, it nevertheless still belongs to the mountaindeciduous broad-leaved forest belt and not to any type else.
