Abstract
This research was performed to study the relationship between vegetation cover and geomorphologic facies in Zirkoh regional which is located 170 kilometers northeast of the Birjand in Southern Khorasan Province. Frist, for better evaluation of plant communities in the region working unit maps were prepared. Then the vegetation types were created using the provided working unit map and field observations. Based on the working unit area and vegetation types the systematic random sampling were used along 3 to 5 transect of 100 m long. Plotes were placed in each transect at 10 m intervals, where in the dominant species lists, vegetation combination and canopy cover were determined. According to the working unit area between 1 to 3 soil samples were taken from depths of 0 to 30 cm of top soil, including sand, silt, clay and other soil factors such as: PH, Ec, phosphorus, potassium which later standard laboratory methods were used for further estimatetion. To determine the most important factors affecting the distribution of vegetation types and the relationships between soil factors, vegetation and the geomorphological factor; the principal component analysis (PCA) was used by PC-ORD software version 4.1. The result showed that among soil factor the sand and silt percentage and potassium content and among the geomorphological factors; the height and the gradient play significant role on the establishment and distribution of plant species in the region. It was found that the soil factors are more important than topographical factors, so that there was more diverse vegetation types in the plain and lower altitudes region, comparison to the mountain and high altitudes region, while it was not observed any certain vegetation types.
