چکیده

In this research the effects of some soil properties on range evening was studied. For the purpose of this study, three sites consisting of shrub land, grass-shrub land and herb land were selected according to the height range and geographical directions. Soil elements including Calcium, Magnesium, Phosphorus, Potassium, CaCO3, Ammonium, Nitrate, Organic Matter, Acidity, EC, Moisture, and Soil Texture were measured. Plant samples were taken in the key areas according to numbered of plant species one by one. Principal component analysis (PCA) was utilized to find the environment gradient. Duncan and variance analyses were used to compare plants evening in the three sites. Results showed that chemical properties such as organic matter and potassium and physical properties such as soil moisture and silt content caused soil fertility to increase and consequently increased ecologic habitats in the soil. This led to the growth of rare species of plants. Because these rare species need high level of soil fertility and consequently causing low canopy evening. Sites with weak soil fertility has a more plants evening than other sites.
