| چکیده انگلیسی مقاله |
Dena Biosphere Reserve located in Iran and is a 550 Biosphere Reserve in the worlds. This research was investigated in the two protected and non-protected areas, in a Dena Biosphere Reserve, Kohkeloye va Boyrahmad province, and central zagros forest, southwest of Iran. Inventory methods designed by systemetic-randomaiz method by use the rectangular plots that were 15×30 meters in the 100×100 m Net. In each plots information include qualities and quantities tree parameter measured. T-test was used to analysis of mean quantities tree parameter differences between protected and non-protected area. Data analyzing was done by Excel and SPSS16 software’s. Results showed that the DBH distribution in the reduced uneven- aged stand in protected area and reduced even aged in the non-protected area. Results showed that the mean of forest characteristics including DBH, height, canopy cover and, and density in the protected area are 38.5 (±5.5), 6.51 (± 0.9), 38 (±5.5) and 530 (±35) and this quantities parameters in protected area higher the non-protected area. Overall results showed that the qualities and quantities tree parameters in the non-grazed area higher the grazed area, and grazing has a negative effect on the qualities and quantities tree parameters. |
