INVESTIGATION OF GROWTH RATE ASSESSMENT FOR LOCUST (ROBINIA PSEUDOACACIA) IN THE EASTERN ROMANIA

Gabriel Murariu

Abstract

Estimating the growth level per unit of hectare and the level of production of wooded areas for accurate obtaining and portfolio is significant in determining the supply of wood for an efficient management system. The present paper is based on the evaluation of six growth seasons locust tree (Robinia pseudoacacia). The monitored sectors are located in the eastern part of the Romania. The climatic gradient can also be neglected due to the nature of the studied areas. The timeframe in which the study was conducted ranged from 2010 to 2015. Some technological factors such as consistency, density, etc. were carefully measured based on annotations in the field. The results obtained through numerical approaches have shown that: (1) estimates of the growth rate can vary significantly when using different statistical and numerical methods; (2) using numerical optimization models, computer simulations can provide accurate estimates of the growth rate and hence the effectiveness of a given forest inventory; (3) common methods of numerical interpolation or uses of neural networks that do not always yield acceptable results.
