摘　　要：全球气候变化对陆地生态系统产生了巨大的影响,植物作为陆地生态系统的主要生产者,不可避免地受到各种环境因素的影响。为了探索全球气候变化背景下早春植物生长所受的影响,笔者归纳了早春植物对不同环境因子响应的国内外文献数据。在既有研究成果的基础上,笔者详细总结了增氮、降水变化对早春植物的功能性状的影响,并对上述变化做了合理的分析。笔者发现目前关于环境因子对早春植物生长影响的试验中,很多都是短期模拟试验,而且大多数试验大多是单一环境因素影响研究,缺乏多种环境交互因素影响的探索。笔者认为在今后的研究中应该将模拟时间进一步延长,增加多种环境交互因子的研究并对造成响应变化的机理进行探索,旨在为我国不同环境因子对早春植物影响的演化研究、生物多样性的保护提供科学依据,从而揭示气候变化背景下早春植物乃至生态系统的变化趋势。Global climate change has had a huge impact on terrestrial ecosystems. As the main producers of terrestrial ecosystems, plants are inevitably affected by various environmental factors. In order to explore the impact of early spring plant growth under the background of global climate change, the author summarized the domestic and foreign literature data of early spring plant response to different environmental factors. On the basis of the existing research results, the author summarized in detail the effects of nitrogen increase and precipitation changes on the functional traits of early spring plants, and made a reasonable analysis of the above changes. The author found that most of the current experiments on the impact of environmental factors on the growth of early spring plants are short-term simulation experiments, and most of the experiments are studies on the impact of a single environmental factor, and there is a lack of exploration of the impact of multiple environmental interaction
