摘要
植被空间分布格局受光、热、水、土等的影响表现出一定的规律性。海拔是影响光、热、水、土等分配的因子之一,进而影响植被分布。为了探索植被沿海拔空间的分布规律,以糯扎渡自然保护区为例,按每100 m为一海拔带把整个保护区划分为13个带,并利用其数字高程模型和植被图,使用ArcView、ArcMap、ERDAS、EXCEL等软件,进行了该保护区植被沿海拔空间分布的研究。通过研究,给出了该保护区13种植被类型的分布规律、适生海拔区间和每一海拔带的优势植被类型,并制作了按海拔带分布的三维立体植被图。该研究成果为开展本保护区的科学研究和管理提供了科学依据。
The spatial distribution of vegetation is following a certain pattern detenuined jointly by factors like light, heat, rainfall and soil etc. Mtitude is a key factor that affects the distribution of light, heat, rainfall and soil, consequently affects the distribution of vegetation. To study the vertical distribution pattern of vegetation in Nuozhadu Nature Reserve, the nature reserve was zoned into 13 belts according to altitude with an interval of 100 meters, then vertical distribution of vegetation in the 13 belts were analyzed using an digital elevation model and a vegetation map with aids of ArcView,ArcMap.ERDAS.EXCEL etc. The outputs of the study included vertical distribution pattern of 13 vegetation types, their suitable altitude range, dominant vegetation types for each altitude belt and a vertical distribution map of vegetation. The results from the study were able to provide with useful information for further study and management improvement of the nature reserve.
