The Determination of phytoclimates based on biodiversity and biological forms in Arasbaran

The area of Study was located in 50 km of northwest of kaleibar and 8 km of Aras river. This area has 38 50 38 - 52 north latitude and 46 44œ - 46 46œ east longitude. Average altitude is 1100 meter from sealveve. The region is bounded to Kalaleh village from north, to Vaigan village from east side, to Elgeneh Chay river from South and Teymour Baigloo village from west side. Rich amount of flora are showed suitable ecological condition and this flora be effected from diversity of climate and soil. Based on growth season and vegetation period all of the plant species were collected from region and determinated. The results were showed that this area has 220 species, 170 genuses and 61 families. We used from Raunkier Danish botanist category. Category of biological forms was done based on the position of live bud from soil surface. This study were showed that this area has 100 Hemicryptophyte species, 58 Phanerophyte species, 43 Therophyte species, 13 Geophyte species, 6 Camephyte species and vegetation physiognomy is with Phanerophyte plants. This ratios change in various ecological regions so as we can determine four climates: Phanerophytic humidity temperate regions, Hemicryptophyte moderate region with partial arid, Terophytic temperate regions and moderate with long arid season and Chamaephytic high width and high mountains. Based of carried out studies and said ratios Arasbaran region was placed on hemicryptophyte with moderate partial raid region. These biological forms include 45, 26, 19, 6 and 3 percent of all species respectively.
