河南山地植被的垂直分布规律

河南山地植被分布的垂直带谱是比较简单,但比较明显.植被的垂直分布规律是:植被垂直带谱基带的植被类型是该山地的纬度水平地带的植被类型;优势垂直带是分布幅最宽的基带,但过渡地带的优势垂直带是基带以上的一个带;植被的各垂直带分布高度的上限从南向北逐渐降低;从基带向上,各垂直带植被类型的变更,类似水平地带由低纬带至高纬带的植被类型的变更.

THE VERTICAL ZONATION OF MOUNTATIN VERTATION IN HENAN

The structure and characteristics of vertical vegetational belt spectrum of mountains in Henan have been studied.The vertical vegetaational belts are simple and obvious.The distributional laws are as follows:1. The vegetational types of basic vertical vegetational belts are just the vegetational types of horizonal zones of mountains.2. The dominant belts are certainly the basic vertical vegetationel belts that distribute widest on mountains.The dominant belts in transitional zonation are above the basic vertical belts.3. The distributional altitudes of the vertical vegetational belts are lower gradually from south to north.4. Changes of vegetational types from basic belts to each upper belt are similar to those from low lat-itude to high latitude of horizonal zones.
