摘要
CO2浓度和温度是影响植物生长的关键因子。目前,以CO2浓度和温度升高为特征的气候变化对植物生长的影响已受到了科学家们的普遍关注。近年来,国内外有关CO2浓度和温度升高对植物影响的报道较多,因而要想对升高CO2浓度和温度对植物的影响进行全面的综述是相当困难的。因此,本文只对国内外近年来有关CO2浓度和温度升高对植物养分含量、分配影响的研究结果作一简要的综述和评析.大多数研究表明:CO2浓度升高,植物养分浓度降低。温度升高及温度和CO2浓度同时升高对养分浓度的影响尚无统一认识。不同的元素、不同的树种,不同的组织在气候变化条件下其养分变化也各异。
Carbon dioxide（ CO2） concentration and temperature are key factors that affect plant growth. At present, effects of global change characterized mainly by elevated CO2 and temperature on plant growth have already been concerned by scientists worldwide. It is quite difficult to review on all aspects of the effects of elevated CO2 and temperature on plant although there are already a lot of researches and reviews recently. Therefore, only approaches and results of researches on effects of elevated CO2 and temperature on plant are summarized and reviewed briefly in this paper, expecting to be helpful to domestic research. Most studies have showed that elevated CO2 decreases plant nutrient concentrations, but there is no consensus on the effects of increased temperature and elevated CO2 and temperature on plant nutrient concentration. Furthermore, the effects of global change on different elements, plants and tissues are different.
