Climate change poses a very serious threat to woody plants, and it is important to study its impact on the distribution dynamics of woody plants in China. However, there are no comprehensive quantitative studies on which factors influence the changes in the area of woody plant habitats in China under climate change. In this meta-analysis, we investigated the future suitable habitat area changes of 114 woody plant species in 85 studies based on MaxEnt model predictions to summarize the future climate change impacts on woody plant habitat area changes in China. It was found that climate change will result in a 3.66% increase in the overall woody plant suitable areas and a 31.33% decrease in the highly suitable areas in China. The mean temperature of the coldest quarter is the most important climatic factor, and greenhouse gas concentrations were inversely related to the area of future woody plant suitable areas. Meanwhile, shrubs are more climate-responsive than trees, drought-tolerant plants (e.g., , , and ) and plants that can adapt quickly (e.g., , and ) and their appearance will increase in the future. Old World temperate, Trop. Asia and Trop. Amer. disjuncted, and the Sino-Himalaya Floristic region are more vulnerable. Quantitative analysis of the possible risks to future climate change in areas suitable for woody plants in China is important for global woody plant diversity conservation.
气候变化对木本植物构成了非常严重的威胁,研究其对中国木本植物分布动态的影响具有重要意义。然而,对于气候变化下哪些因素影响中国木本植物栖息地面积变化,目前尚无全面的定量研究。在这项荟萃分析中,我们基于最大熵模型预测,调查了85项研究中114种木本植物未来适宜栖息地面积的变化,以总结未来气候变化对中国木本植物栖息地面积变化的影响。研究发现,气候变化将导致中国木本植物适宜总面积增加3.66%,高度适宜面积减少31.33%。最冷月平均温度是最重要的气候因子,温室气体浓度与未来木本植物适宜面积呈负相关。同时,灌木比乔木对气候更敏感,耐旱植物(如……)以及适应能力强的植物(如……),它们在未来的出现频率将会增加。旧世界温带、热带亚洲和热带美洲间断分布以及中国喜马拉雅植物区系更为脆弱。对中国木本植物适宜区域未来气候变化的潜在风险进行定量分析,对全球木本植物多样性保护具有重要意义。
