Diversity of Vegetation in Pardisan Forest Park and Climatic Adaptation of its Dominant Species in the Region

The relation between a climate and its vegetation cover is a function of special condition. Climate is considered as one of important ecologic factors and has the most important effect on quality and quantity of vegetation cases. Selection of plants per improvement and recovery of each region should be simple implemented based on the knowledge of that region concentration of special species of each region is determined by three factors namely temperature, precipitation and humidity, which today are named as biological variables. The goal of this study was to investigate diversity of vegetation in Pardisan forest park and climatic adaptation of its dominant species in the region.
In this research by collection of tremendous species of vegetation coverage of Pardisan Park, preliminary recognition of vegetation cover and collection of information such as their names, growth forms, dispersion and application in the land landscape was done. Given the Pardisan Park management didnt have any statistical data of the numeral and position of hand planted plants. The general location and areas of prevailing species of the park was determined and was marked on the map of the park by using GIS software. The frequency of each gens and of each family were ordered by each software. In next step after getting the information and statistics and the values of climate logical parameters related to geophysical station from meteorological organization, we studied them and analyzed their relation to the survival of prevailing species of the park.
Climatology and ambrotermic diagrams and curves were plotted based on climatic parameters and finally echo gram curves of dominant vegetation cover of Pardisan Park were analyzed based on climatology parameters.
Results show that, given that there is no significant difference in the micro climate of different areas of the park, factors such as microclimate, soil, direction and amount of access of plants to water resources play the most important role in the diversity of vegetation even of Pardisan forest park.
