摘要
近年来,气候变暖对人类生活的影响越来越明显,同时气候变暖也从一个学科问题上升为一个全球性问题,并对作为地球主要生产力的植物光合作用产生了影响,因此研究气候变暖对植物光合作用的影响以及植物适应气候变化的机制十分必要。自气候变暖问题提出以来,大量学者对其影响和机制进行了大量的研究,但目前还缺乏这方面的综合性研究报道。本文对气候变暖对植物光合作用的影响进行了系统的综述,将影响因素简单分为温度、CO2浓度、盐分和干旱,最后提出了该领域未来的研究重点和目标。

Abstract
The impact of climate warming on human life has become more and more obvious in recent year. At the same time, climate warming has moved from a disciplinary issue to a global one. It also influences the plant photosynthesis which was the primary productivity of the Earth. So it’s necessary to research on the effects of climate warming on plant photosynthesis and the mechanisms of plant adaptation to climate change. Since the issue of climate warming was raised, a large number of scholars have done a lot of research on its effects and mechanisms while there is still a lack of generalized reports on research in this area. This paper provides a systematic review of the effects of climate warming on plant photosynthesis. We simply divided the impact factors into temperature, CO2 concentration, salt and drought. Finally, future research priorities as well as goals in this area are proposed.
Key words: Climate warming; Photosynthesis; Metabolism; Salt stress; Drought
