The Comparative Study of Temperature Elements in Forest and Non-forest Environment: Case Study: Climatic and Research Station of Botany Park of Tehran University

In this article we have studied temperature elements (dry temperature, wet temperature, minimum and maximum temperature) and their fluctuations forest and non-forest environments. In order to observe temperature in two climatic stations the study was carried out in three elevations of 170, 130 and 5 cm at three local time zones 07:30, 12:30 and 18:30. Results showed that in forest environment the average dry temperature and maximum temperature was low as compared with non-forest environments and great differences occurred in 5 cm elevation in forest and 4.6C at 12.30 p.m. and 4.2C at 18:30 p.m. Average minimum temperature in forest environment was higher than non-forest maximum differences which was in 170 cm elevation at 06:30 a.m. as high as 0.3C. The authors did not observe any trend in wet temperature element.
