1) Sapwood area
边材面积
1.
In this article, sapwood area is used as a scalar to extrapolate the stand water use from whole tree water use measured by heat pulse velocity recorder(HPVR).
该文在单木液流测定的基础上 ,采用边材面积作为纯量 ,对京北山区水源保护林的主要树种油松、刺槐林进行由单木到林分耗水的推算 。
2) ratio of leaf area to sapwood area
叶面积/边材面积
1.
Combining with the tree morphological features and sap flux density,the whole-tree transpiration,canopy stomatal conductance,and ratio of leaf area to sapwood area were calculated by simplified Whitehead and Jarvis equation,and the effects of tree height on these three parameters were analyzed.
结合树木的形态特征、液流密度和简化的Whitehead&Jarvis公式,分别计算了整树蒸腾、冠层气孔导度和叶面积/边材面积比值,分析了树高对整树蒸腾、冠层气孔导度和叶面积/边材面积比值的影响。
3) Leaf/sapwood area
叶/边材面积比
4) bright sap
净面边材
5) The area of the stream out side
出汽边面积
