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。

Abstract:

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).
