摘 要 ：光呼吸是C₃植物体内重要的代谢过程。本文阐述了人类经济发展的同时对自然环境所产生的种种影响后果，包括CO₂浓度升高、紫外辐射增加、温度变化、强光等环境因子对植物光呼吸所产生的影响，如直接或间接导致植物光呼吸速率的变化，进而在植物生理和生态上产生相关的效应。C₃植物在受到环境胁迫时，可以通过光呼吸协调代谢功能,在一定程度上发挥规避环境、尤其是极端环境胁迫的效应。因此，可通过调节C₃植物的光呼吸规避环境胁迫，这为光呼吸研究在环境生态学领域的拓展指出新的方向。

Abstract:Photorespiration is an important metabolic process in C₃ plants. This article analyzes the effects of human and economic development like increased CO₂ emission, ultraviolet radiation, temperature, light, etc., which influence photorespiration such as directly or indirectly changing photorespiration rate that can lead to secondary effects on plant physiological and ecological development. When C₃ plants are under environmental stress, photorespiration corresponds to metabolism which eludes the stress, especially when the environmental stress is severe. Hence photorespiration of C₃ plants under environmental stress leads to a new direction of research in environmental ecology and photorespiration.
