摘要：The aim of this study was capability investigation of the satellite KFA-1000 colour and panchromatic images to determine an elongated tree border of two different vegetation communities of forest and rangeland, which have resulted from a natural and anthropogenic environmental gradient in northern flank of Alborz range. In this study we investigate the use of stereoscopic mapping to produce a classification of a tree line ecotone in Northern Alborz Mountains of Vazroud Basin using visual images which has supported with the field investigation as ground control in June 2008 as well. From north toward south parts the transition with altitude is from dense forest to treeless rangeland and herbaceous vegetation. The relationships between the probability of class membership for the two end-member classes of scrub and forest and rangeland and the percentage ground cover of these vegetation classes were highly significant: r2 = 0.89 and r2 = 0.95, respectively.
