Study of environmental factors effects on vegetation,case study: Iran

摘要：

The distribution of plant species under environmental factors effects was examined in Veresk rangelands of Iran.Six vegetation types were recognized in the study area.Canopy cover percentage of plants in different types was estimated based on randomized‐systematic vegetation sampling procedure within 1 m2 quadrates.Soil sampling was performed from 0‐30 and 30‐60 cm depths.The characteristics of soil samples in addition to slope, aspect and elevation of quadrates locations were considered to test their relations with distribution of vegetation using multivariate analysis.The results showed that separation of understudy types was mainly affected by texture, gravel percentage, N, OM, pH, and Ec.
