| 3. | The result showed there was some logistic relation between them , but not significant
利用逻辑斯蒂回归分析表明，树干熏黑高度和胸径对虫害发生数量有一定影响但不是很显著。 |
| 4. | The number of trees planted should be more than adequate to compensate for the trees lost in terms of the aggregate dbh
以树木胸径的方法计算树木损失的数量，然后栽种相等或更多的树木作为补偿。 |
| 5. | 3 the influence of water on vegetation growth : ( 1 ) soil water shortage refrains the height , basal diameter and stock of trees
3土壤水分对林分生长的影响： ( 1 )土壤水分亏缺严重制约着树高、胸径和材积的生长。 |
| 6. | Description : large evergreen trees to 30 m tall and 1 m in dbh ; twigs glabrous except grayish puberulous on nodes when young
形态特徵:常绿大乔木，高15 - 30米，胸径可达1米；小枝无毛，但嫩时芽及节上被灰褐色、平伏的微柔毛。 |
| 7. | However the density of trees increased , and at the same time , shrubs density , maxium proportion of tree number of certain dbh range trend to decrease
而乔木密度呈增加趋势，而灌木密度和乔木树种的最大株数比例的胸径范围呈不断降低趋势。 |
| 8. | The model was reliable and accurate , it can be used to forecast of diameter growth and can amplify and develop the methods of population ' s development and prediction
经检验，该模型预测胸径的生长量具有较好的可靠性和精度高等优点，从而丰富和发展了种群增长模拟与预测预报的方法。 |
| 9. | Result showed that different waterlogging depths have obvious effects on tree height , diameter at breast height , under branch height , trunk morphological structure , stem base form , and growth process
结果表明：不同水分条件对池杉的树高、胸径、枝下高、干形、树干基部形态及生长过程均产生明显的影响。 |
| 10. | The results show that the water consumption of transpiration can be reckoned through standard specific conductivity of standard tree and the relative model between breast height diameter of tree and sapwood area
结果表明，通过标准木的标准比导率和树木胸径和边材面积的相关模型，可以比较准确地推算出林分的蒸腾耗水量。 |
