5) diameter at breast height(DBH)
胸径
1.
Taking Guangxi Standard Standing Volume Formula as a basis,electric volume table about the main timer tree species has been made with VB programming language,with which you just need to input the values of diameter at breast height(DBH) and tree height rather than table checking or manual computation,and then you can obtain the corresponding timber volume value.
利用该程序,不需查表或手工计算,只需输入或批量导入胸径和树高值,即可求得相应的材积值。
2.
Regression equations among the leaf area index(LAI),bamboo stock diameter at breast height(DBH),density of bamboo plantation and the number of branch strata were set,and it was discovered that there were close correlations among these indices.
通过建立四季竹叶面积指数与立竹胸径、密度、枝盘数等因子间的回归经验式,发现其间存在着显著的相关关系,且均是影响竹笋产量的重要林分结构因子,其中叶面积指数与竹笋产量紧密相关,当叶面积指数为10。
