中文摘要 | 本研究係以福山闊葉林兩孔隙更新時期的兩樣區,已伐取94株喬木之資料,用兩 組異率迴歸式,以胸高直徑估算建造期與成熟期林分,樹體各耜位之生物量及葉面積。經分 析結果顯示,所有迴歸式皆呈現極顯著差異。利用綜合直線迴歸法和95%信賴區間兩種方法 比較兩組迴歸式,顯示各耜位生物及葉面積兩組迴歸式無差異。此一結果可確定只需要一組 迴歸式,即可以胸高直徑估算兩孔隙更新時期福山闊葉林的生物量和葉面積。 |
英文摘要 | Two groups of allometric regression equations were developed. These were derived from a mature-phase stand and a building-phase stand caused by gap regeneration, respectively, and relate the aboveground tree biomass component and leaf area to tree diameter at breast height (dbh) based on harvesting 94 trees in the Fushan broadleaf forest of northeasten Taiwan. After analysis, all equations were highly significant. Two methods, the general linear model (GLM) approach and 95% confidence intervals, were used to test whether the 2sets of equations are statistically equivalent. The results show no stand effect for the equations of biomass component and leaf area. It does appear that common equations can be applied the 2 stands of the Fushan forest due to gap regeneration. |
