evaluation variation trend in qualitative measures in natural even-aged stand in kheyroud forest
in this research with using of obtained information from a natural fraxinus the variation of quantities and qualitative measures of current stand in an 8 year period was conducted in chelir part of kheyroud forest. data collection was conducted by full callipering method in two periods of 1384 and 1392. during the period of study the parameters of dominant mean height and relative crown height ...
متن کاملDURAMETR - A New Stand for Estimating the Durability of Textiles
The new stand called DURAMETR with a computer program based on LabVIEW software to investigate textile creep is described. An analysis of filament creep under constant load is presented. A comparative analysis of changes of filament strain under constant load obtained from DURAMETR, and the INSTRON tester which uses the XII cyclic program is presented.
متن کاملa study on the dimensional characters of even-aged and mixed fraxinus excelsior stand (case study: chelir district, kheyrud forest)
knowing and conducting studies on size characters of trees is essential for assessing the tree volumeand/or other statistical parameters and also forest management. the characteristics of 529 treesincluding diameter at breast height (dbh) and total height were measured in an even-aged fraxinusstand for two periods from 2005 to 2012 in chelir district, a part of experimental kheyrud forest.resul...
متن کاملCrown Management and Stand Density
Stand density management allows a forester to utilize mortality and promote individual tree vigor. However, even after four decades of spacing studies, planning for stand density management remains a difficult problem. Forest management approaches the problem with sophisticated analysis, but the heart of the analysis depends on statistical growth models fit to data from empirical field trials. ...
متن کاملThe Application of Bayesian Model Averaging in Compatibility of Stand Basal Area for Even-Aged Plantations in Southern China
Stand growth-and-yield models include whole-stand models, individual-tree models, and diameter distribution models. Based on the growth data of Chinese fir (Cunninghamia lanceolata [Lamb.] Hook.) in Fenyi County, Jiangxi Province, in southern China, Bayesian model averaging (BMA) was used to forecast stand basal areas by combining these three types of models into a single predictive model. BMA ...
