关于植物种群的光能利用,植物生产力和净同化率等近年来有不少研究,但其中除了研究植物个体的净同化率外,多为农作物等草本植物群落或者用林业采收法的研究。对于自然木本植物种群及其不同层的植物与光、温度分配关系中用测定光合作用方面的研究工作还不多。 光合作用强度的测定,目前多用离体叶片或盆栽植物进行或者用收集落叶量与砍伐林木
In recent years, many studies have been done on the light energy utilization, plant productivity and net assimilation rate of plant populations. However, in addition to studying the net assimilation rate of plant individuals, most of them are herbaceous plant communities such as crops or the research on forestry harvesting methods. There is not much research work on the determination of photosynthesis in the relationship between plant and light and temperature distribution of natural woody plants and their different layers. The determination of photosynthesis intensity, the current use of more leaves or potted plants, or to collect the amount of deciduous and deforestation
