摘　　要：光是森林生态系统的关键能源输入。森林光环境的演变机制很复杂,我们通过对林缘、林内和林窗的光环境相关指标及监测方法进行了归纳总结,并在分析森林光环境特征的基础上,从时间尺度上对其日变化、季节动态和年际变化三个方面进行了总结。同时从个体、群落、生态系统等方面对森林光环境生态作用进行了探讨,旨在为深入了解森林植被时空动态与光环境间协同演变机制提供参考,为促进森林可持续管理提供依据。Light is a key energy input to forest ecosystems.The evolution mechanisms of light environment in forest are complex.We summarize the light environment indicators and monitoring methods at the forest edge, forest interior and forest window, and also summarize their daily, seasonal and interannual changes based on analyzing the characteristics of light environment in forest on a temporal scale.At the same time, the research progress of the forest light environment at home and abroad were reviewed from vertical and horizontal gradient.It also explores the ecological role of the forest light environment in terms of individuals, communities and ecosystems, with the aim of providing a reference for understanding the synergistic mechanisms between the spatial and temporal dynamics of forest vegetation and the light environment, and providing a basis for promoting sustainable forest management.
