冬季异常高温对亚热带地区树木休眠解除的影响
Influence of abnormally high temperature in winter on tree dormancy release in subtropical region
[目的]冬季积冷是影响树木休眠解除的主导因子,受全球气候变暖影响,冬季异常高温的发生频率增加,尤其是亚热带地区冬季常出现 20℃及以上异常高温。然而,现有积冷模型是基于温带气候特征建立,温带地区冬季气温偏低,无法真实准确地识别和处理这种异常高温,导致模型不能完全适用于亚热带树种。在气候变暖背景下,冬季异常高温对亚热带树种休眠解除的作用究竟如何,积冷模型如何处理这种异常值,亟待研究解决。[方法]为了探究亚热带地区树种对冬季异常高温的响应规律,本研究…查看全部>>
[Objective]Cold accumulation in winter is the main factor affecting tree dormancy release.Under the influence of global warming,the occurrence frequency of abnormal high temperature in winter increases,especially in subtropical regions where abnormal high temperature is often 20℃or above in winter.However,the existing cold accumulation model is based on the characteristics of the temperate climate,the temperature in the temperate region is low in winter,and …查看全部>>
