Aleksiychuk Y. Peculiarity of biometric structure and merchantability structure of matures and overmatures Pine forest stands in Polissa of Ukraine

Object - regularities of distribution and interrelations of biometrics parameters of natural matures and overmatures Pine forests stands. Aim - to establish the biometrics characteristics of natural matures and overmatures Pine forests stands in Polissa of Ukraine and develop the appropriate norms their merchantability. Methods - in investigation process were using modern methods of forestry biometric and mathematical statistic. The main of them are correlation and regression analysis, estimation methods, models and approximation biometric indicators, methods of generalization and treatment forestry information. The collection of research information was fulfilled according to current instructions and standards. For estimation of mathematical models are used the typical statistical methods. The standard of merchantability for natural matures and overmatures Pine forests stands were treatment with involving statistical modulation methods. They based on the plenty of practical materials and checking ofthem accuracy was done. Novelty - in first regularities of biometric structure are done for natural matures and overmatures Pine forests stands. General rows of trees distribution by diameter classes and quality categories are obtained. Regional norms for estimate merchantability structure of these stands stock are established.Results of research - for implementation in practice of forest inventory and forestry the follow is being proposed: general rows of trees distribution by diameter classes and quality categories, merchantability tables for estimate of stock in natural matures and overmatures Pine forests stands. Branch - forestry.
