摘要

Preliminary height models, a volume model, a site index model and a survival analysis for Pinus halepensis Mill. in Chalkidiki (Northern Greece) were preliminarily developed based on measurements of 20 experimental plots established in 2010. The data for the height, volume and ‘mortality’ models consisted of 790 observations taken from 40 trees (20 dominant and 20 co-dominant). An equation derived from the hyperbolic function was selected to model the dominant height and the volume development. The height growth model was used as a guide curve to develop two site index curves. Mean dominant and codominant height was estimated at 10m (site I) and 7m (site II) (base age of 17 years). Kaplan-Meier survival and hazard functions applied for the ‘mortality’ analysis, confirmed the site index curves developed from the height model (SI10 and SI7).
