Abstract

The purpose of this study was to examine the relationships between plants communities and certain PHYSIOGRAPHICal variables including elevation, slope and aspect as well as rainfall in BABOLROOD BASIN, Mazandaran province. Vegetation and topographic maps of the study area with the scale of 1:50000 were digitized. Digital Elevation Model (DEM) was constructed and slope and aspect images were derived from DEM. Rainfall map of the area was also prepared. Vegetation map was coreGIStered to other images. At least 90 points were randomly located and sampled in each vegetation types and their values were extracted from the slope, aspect, elevation and rainfall maps. Vegetation and different layers were overlaid and cross-classifed to examine the impact of the variables on discrimination of different PLANT COMMUNITIES. The result of ANOVA showed that there is a significant difference between vegetation types and the variables. Discriminant Function Analysis was performed to understand the discriminatory power of the variables. The results confirmed that the attitude and rainfall are the most important variables to distinguish spatial distribution of PLANT COMMUNITIES in the study area.
