森林生态系统植物热值的研究综述

Review on the Studies of Plant Caloric Value in Forest Ecosystem

植物热值是衡量植物体能量利用策略的指标,反映了绿色植物在光合作用中转化光能的能力,是评价生态系统能量固定﹑转化和利用效率的基础。该文论述了森林生态系统中不同群落演替阶段、群落内不同层次、相同林内种间关于植物热值研究相关成果,以及森林热值的季节动态,并对热值的研究进行了展望。

Plant caloric value is the index which measures the energy utilization policy in plants. It reflects the ability of photosynthesis in green plants, and it is the basis to evaluate the efficiency of was the basis of energy fixed, energy conversion and energy utilization in ecosystem. This paper reviewed the research achievements on the plant caloric value in the succession stage of different community, in the different layers in community, in the interspecific crossing of the same forest, and reviewed the the seasonal variation of plant caloric value. Finally, this paper look into the distance to the research trend of plant caloric value.
