摘要
基于GIS技术,探索岷江上游植被空间格局与地形因子(高程、坡度、坡向等)之间的关系,得出不同地形地貌区的植被分布特征。研究表明,不同地形地貌区植被的分布状况不同,各种植被因受地形、水份等因素影响而具有一定的分布特征,GIS技术在植被空间分异研究中有很大的应用前景。
The relationship between vegetation distribution and different terrain factors, such as elevation, gradient, and aspect etc. in upper reaches of the Min River ＇based on GIS techniques are discussed to obtain the characteristics of vegetation distribution in various physiognomy areas in this paper. The results show that vegetation has their respective distribution characteristics due to the i^ffluence of terrain, moisture etc., and GIS has a good prospect of application in landscape ecology.
