| الوصف: | It is so important to know about ecological characteristics of trees of a stand, in forest management. The first step to achieve this knowledge is to recognize the spatial pattern of trees. Therefore, regarding the enviro-economic importance of F. orientalis in hyrcanian forests, this study checked spatial pattern of these trees. In order to do this research, 5 one-hectare plots with homogeneous environmental conditions were inventoried in natural stands of Fagetum in Nave Asalem, Guilan province accidentally. Then, measuring the angle between fagus trees and using indicators of uniform angle index (Wi), Mean directional inedx (Ri), Mean of angles index and Clark-Evans (CE), the spatial pattern in Fagus orientalis was analyzed. The results showed clumpy pattern of the Fagus orientalis trees which is also tended to be random, and using Wi, Ri and CE indicators together provides better results to determine the spatial pattern of trees. Also, using angular indicators, besides the high accuracy due to the lack of need to measure distances between trees, speeds up spatial pattern determination of forest stands. |
