摘  要:
高山植物的光合作用受强辐射、低温和干旱环境的影响。近年来,大气CO_2浓度上升和全球气候变暖的趋势日益明显,影响着高山植物的光合生理。本文综述了强辐射、低温和干旱等高山环境因子以及全球气候变化引起的大气CO_2和温度上升对高山植物光合特性的影响,并提出未来高山植物光合生理的研究热点主要是开展不同地域的高山植物光合特性研究,环境因子交互作用对高山植物光合特性的影响研究,不同植物的光合特性对全球气候变化响应的差异,模拟土壤有效养分含量增高对高山植物光合特性的影响,建立数学模型预测全球气候变化对高山植物动态的影响以及通过长期定位研究探索不同生长阶段高山树木的光合特性。

摘  要:
Photosynthesis of alpine plants is affected by intense irradiance,low temperature and drought. Moreover,rising atmospheric CO_2 concentration and global warming exert a profound influence on photosynthesis of alpine plants in recent years. This paper reviewed the effects of intense radiation,low temperature,drought,elevated atmospheric CO_2 concentration and global warming on photosynthetic characteristics of alpine plants. Future researches should focus on photosynthetic characteristics of main plants in different alpine regions,interactive effects of environmental factors on photosynthetic characteristics of alpine plants,the effects of simulated soil available nutrient content on photosynthetic characteristics of alpine plants,the impact of global climate change on photosynthetic characteristics of alpine plants using mathematical models,and photosynthetic characteristics of alpine plants at different growth stages by long-term positioning study.
