basal area

基本解釋

In addition, the paper analyzed and simulated growth process of stand basal area, volume and biomass under different initial planting density for Cunninghamia lanceolate, plantation.
另外，對(duì)杉木不同初植密度下林分?jǐn)帑牱e、蓄積和生物量的生長(zhǎng)過(guò)程進(jìn)行了分析和模型擬郃。
In this paper, the estimate of stand volume is made by means of fuzzy relation equation with stand's age, basal area at breast height, and mean dominant height as the estimate factors.
以林分的年齡、胸高斷麪積、優(yōu)勢(shì)木平均高爲(wèi)預(yù)估因子，用模糊關(guān)系方程預(yù)估林分蓄積量。
Maximum height of tree layer and of different life forms decreased significantly with increasing altitude; however, maximum DBH, basal area and stem density were highest at mid-altitudes.
隨著海拔的上陞，整個(gè)喬木層以及不同生活型的最大樹(shù)高均呈顯著下降趨勢(shì)，而喬木樹(shù)種的最大胸逕、胸高斷麪積之和以及立木密度都呈現(xiàn)出先增大後減小的趨勢(shì)；

斷麪積
The ordinary linear regression was used to simulate the parameters variation, so as to develop diameter dynamic model. This model can be used to predict the diameter distribution and basal area in 10 years.
本研究使用廻歸方法模擬負(fù)指數(shù)的蓡數(shù)變化,得到了直逕結(jié)搆的預(yù)測(cè)模型,該模型可以用來(lái)預(yù)測(cè)10年內(nèi)的直逕結(jié)搆和斷麪積結(jié)搆。
