叶片是植物进行光合作用的主要器官。光合作用是植物获得能量和干物质的基础。叶面积和叶片密度的分布是构成竹林冠结构的基本条件。合理的竹林冠结构是获得最大生物产量的决定性因素之一。准确掌握箭竹林和单株成竹叶面积的空间变化规律,了解林分叶面积密度的垂直变化和竹林冠的最大光合作用区,对揭示竹林同化产物的运输状况,研究竹林冠的光合作用和蒸腾作用,为缺苞箭竹的造林、花后复状更新的密度调节提供理论依据,从而为大熊猫建立稳定的主食竹基地。
The leaves are the main organs for photosynthesis in plants. Photosynthesis is the basis for plants to gain energy and dry matter. The distribution of leaf area and leaf density is the basic condition for forming bamboo canopy structure. Reasonable bamboo canopy structure is one of the decisive factors to obtain the maximum biological yield. Accurately grasp the spatial variation of bamboo forest area and individual bamboo leaf area, understand the vertical change of leaf area density and the maximum photosynthesis area of bamboo canopy, and reveal the transport status of assimilation products of bamboo forest, photosynthesis of bamboo canopy and Transpiration, providing the theoretical basis for the afforestation of Fargesia denudata, the density adjustment of rejuvenation after flowering, thus establishing a stable bamboo base for the giant panda.
