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。
补充资料：当量比表面直径、表面积体积平均直径
分子式：
CAS号：
性质：又称当量比表面直径、表面积体积平均直径。是颗粒群表面积分布的平均直径。其意义为与颗粒群的粒形相同，总体积相同、总表面积相同，且粒度均匀的一个假想颗粒群的粒度。亦即指与该颗粒群的粒形相同，比表面积相同的一个颗粒的粒度。
