Introduction of plant groups of Yahya Abad region and their relationship with environmental factors
The region of Yahya Abad is located at Southern slops of Karkas mountains with about 6000 hectare area, at 35 kilometer-SW of Natanz in Isfahan, is one of arid mountain ecosystems in Iran. The aim of the study is grouping the plant species and their relationship with various environmental factors such as elevation and soil characteristics. sampling carried out in systematic-random method with 1.5×2m quadrates and percentage of plants cover estimated. In this research different methods of Cluster Analysis and Ordination were performed in order to study of plant groups and their relationship with environmental factors. Cluster Analysis demonstrated eight plant groups and Different methods of ordination indicated the altitude factor as the main factor in the separation of plant groups. Due to relatively uniform topography and livestock's grazing in this region there wasn’t clear relationship between altitude and diversity indeces.
