摘　　要：现代林业生产实质上是经营光合作用的企业,因林业经营和管理的森林生产力高低受制于树木的光能利用率大小。本文回顾了光照和辐射与林业生产的关系研究,剖析光谱、光时和光强3个因素对林业生产的影响。随着林业科学技术的发展,今后在选育高光能利用率的林木品种、模拟天然林合理的林分结构以及制订整套科学的经营措施和管理方案,将成为有效提高森林光能利率的方向。Modem forestry production is an enterprise of managing photosynthesis, and is affected by the rate of using light energy in the tree size because of the high and low productivity of forest management. This paper reviewed the research on the relationship between light and the radiation and forestry produc- tion, and analyzed the effects of spectral components, illumination time and light intensity on forestry pro- duction. With the development of forestry science and technology, such factors as the rate of tree species selection of high light energy utilization ,the simulation of natural reasonable forest stand structure ,and the formulation of management measures and scientific management scheme would become effective ways to improve forest light rate in the future.

关 键 词：光能利用率 光谱成分 光照时间 光照强度 生产力
