SURVEY OF AFFECTED ECOLOGICAL FACTORS TO JUNIPERUS EXCELSA REGENERATION IN GHASEMLOU VALLEY BY EMPLOYING THE ECO-PHYTOSOCIOLOGICAL METHOD
Journal Title: Romanian Journal of Biology - Plant Biology - Year 2017, Vol 62, Issue 1
Abstract
Physiographic maps of Juniperus excelsa distribution including hypsometric, slope and direction maps have been carried out at the scale of 1:8854 in the studied area by ArcView 3.2a. To study the field, Braun-Blanquet method was used. Sample plots located as a randomly systematic method used quadrate minimum area (40 40m2). The relationship between qualitative and quantitative species features and ecological properties were determined using CCA ordination method through PC-ORD Ver.4. The establishment of species had positive correlation with slope degree and direction, soil texture, pH and altitude. Sorensen similarity index surveyed between communities which contained Juniperus excelsa species using NTSYS-pc Ver.2.02e.
