Abstract
This study was carried out in order to state the functional differences between the pure oriental spruce stands in subalpine zone. In the research, the pure oriental spruce stands in the subalpine zone were evaluated according to their wood production (F1), erosion control (F2), water production (F3), grass productivity-wild life habitat (F4), scenic beauty (F5) and avalanche prevention (F6) functions. Functional characteristics were rated as a scalar value between 1 (the worst) and 5 ( the best) according to some observations, and exact differences were fixed between the functional characteristics of the treeline and the timberline stands. Determinations were realized in total of 46 sampling plots. 23 of the sampling plots were in treeline and 23 of them were in timberline. According to the results the F1, F2 and F6 values in the timberline were more effective than treeline stands. However F3, F4 and F5 values in the treeline were more effective than timber line stands. The average F1 value was 1.22 in the treeline and 3.04 in the timberline, F2 value was 3.0 in treeline and 3.61 in timberline, F3 value was 2.91 in the treeline and 2.43 in the timberline, F4 value was 3.35 in the treeline and 2.74 in the timberline, F5 value was 3.70 in treeline and 3.43 in timberline. Average F6 value was 3.52 in the treeline and 3.57 in the timberline. The functional values from treeline and timberline stands were compared by discriminant analysis and 41 of the sampling plots (89%) were estimated in their real groups.
