摘　　要：应用1986年和1994年两个时期TM图像判读制图．编制两期森林景观类型图，在ARC／INFO系统的支持下，建立空间信息库，套合叠加，获取子午岭地区森林景观类型动态转移数据矩阵，应用Markov链模型对未来森林景观格局趋势进行预测分析，总的趋势是朝着好的方向发展。但封、育、管、护、造林与毁林破坏同时并存的现象，增加了森林恢复的难度．By interpretation of 1986 and 1994's TM image, two kinds of forest land-scope type map was compiled. The dynamic transfer date matrix of forest landscope type inZiwu mountains was also obtained through constructing space information base and inter-linking the two kinds map using ARC/INFO software- Analysis and prediction on the devel-oping tendancy of forest landscope patterns with Markov chain model showed that is to-wards advantageous aspect but the difficuIt of recovering fdrest confronting is increasingwith destroy and cIosed forest, management, protection and afforestation at the same timeexist.
