The paper investigated the forest landscape dynamics in the north of the Funiu Mountain, where considerable attention has been drawn in issues of slowing down the agricultural expansion into the remaining natural forests. Based on the theory of landscape ecology, the terrain gradient of forest landscape dynamics were examined by using geographic information system. The results showed that terrain niche index was valuable in describing the forest landscape dynamics in the north of the Funiu Mountain. In 1986 and 2003, the predominant ranges of forest landscape change on terrain niche index were 9-30 and 10-30 respectively and there was a slight trend of up slide. From 1986 to 2003, the three predominant ranges of forest landscape change on terrain niche index in the areas of the forest landscape unchanged, the forest landscape converted to non-forest landscape, and the non-forest landscape converted to forest landscape were 10-30,5-12 and 4-10,18-24 respectively. In addition, by using spatial analysis in Arc/GIS 9.2 and Spss 10.0, the correlation of forest landscape change and the terrain gradient were analyzed. It indicated that there were notable correlations between them, especially in predominant ranges of terrain gradient.
