| Sumario: | This study aimed to adjust the hypsometric model of Trorey, Henricksen, Curtis and Stoffels in ecosystems of mopane (Colophospermum mopane) based on data from permanent plots established in Mabalane, Gaza Province, Mozambique. Statistical adjustment as coefficient of determination R2% and standard error of estimate (Syx%) were determined. Adjustment equations were validated using Chi-square and residual graphic analysis made. The results showed that the Stoffels model was presented the best adjustment compared to the other models, with R2%= 49.92 and Syx%= 17.97 satisfactory for all tested models.doi: 10.4336/2011.pfb.31.66.155 |
