摘要
本文对陕西省化龙山植被的垂直分布特点进行了初步研究。文中采用了数量分类结合对群落生态特点及区系组成的分析,划分出森林植被垂直带如下: 常绿、落叶阔叶混交林带,海拔1600m以下;落叶阔叶林带,海拔1600-2200m;亚高山针叶林带,海拔2200-2917m。
In this paper, the characteristics of the vertical distribution of the forest vegetation on Hualongshan Mountain was discussed. According to the altitudinal distribution of main woody-plant communities, using the methods of quantitative classification and the analysis combining the ecological physiognomy
and floristic composition of various altitude, three vertical zones of forest vegetation may be identified:1. The evergreen and deciduous broad-leaf mixed forest zone below 1600m.2. The deciduous broad-leaf forest zone (1600-2200m).3. The submountain coniferous forest zone (2200-2917m).
