This paper investigated the forest landscape dynamics in Luoning County, the Yiluo River Basin, 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 integrated geographic environmental factors on forest landscape dynamics were examined by using geographic information systems. The results showed that geographic factors such as elevation, slope, distance from village centers, and distance from forest edge had significant impacts on forest landscape changes, and the integrative geographic environmental factors index was valuable in describing the landscape dynamics in Yiluo River Basin. In 1983 and 1999, the predominant ranges of forest landscape change on geographic environmental factors index were 12-30 and 10-30 respectively and there was a slight trend of downslide. From 1983 to 1999, the three predominant ranges of forest landscape change on geographic environmental factors 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 11-30、1-8 and 6-13 respectively. In addition, by using spatial analysis in ArcGIS 9.2 and SPSS 10.0, the correlation of forest landscape change and geographic environmental factors index was analyzed. It indicated that there were notable correlations between them, especially in predominant ranges of geographic environmental factors index.
