Abstract:
The relationships between the spatial pattern of vegetation in Yaoxian County and the terrain factors such as titude,slope,and aspect were analyzed using GIS. Yaoxian County was divided in to several districts ac-cording to its topographical state. The spatial pattern of vegetation was analyzed according to these terrain parame-ters and changes in vegetation index. The result showed that vegetation spatial pattern had a close relationship with terrain parameters.
