摘　　要：以陕西省耀县为例,通过GIS空间分析方法,分析了耀县植被空间分布格局与地形因子(高程、坡度和坡向)的关系,研究了植被指数随地形的变化趋势。研究结果表明,植被空间分布与地形因子关系密切,并呈现一定的规律性。The relationships between the spatial pattern of vegetation in Yaoxian County and the terrain factors such as altitude, slope, and aspect were analyzed using GIS. Yaoxian County was divided into several districts according to its topographical state. The spatial pattern of vegetation was analyzed according to these terrain parameters and changes in vegetation index. The result showed that vegetation spatial pattern had a close relationship with terrain parameters.
