采用物候学研究历史气候方法问题的讨论——答《再论唐代长江上游地区的荔枝分布北界及其与气温波动的关系》一文

A Discussion on Research's Method of Historical Climate with the Phenology:Answers on the Northern Boundary of Litchi's Distribution in the upper Yangtze River in Tang Dynasty and the Relationship with the Temperature Fluctuations

根据成都、万州等地区长时段的历史文献记载和现在植物状况来看,唐代这两个地区是应该有荔枝生长的。三种分布类型都应有气候学的指示意义,只是在显现气候指示程度上有差异。所以,成都和万州荔枝的生长分布有一定气候指示意义。区域小气候是受大的气候背景变化影响的,只是由于小区域的自然差异会左右受大气变化影响的程度。所以,长江上游荔枝分布是可以指示气候的。历史气候的研究应树立宏观、长时段的研究视角,重视田野考察,讲求逻辑思维,充分利用现代科技手段。

According to the long-term historical document records and the present plant condition,There are Litchi＇s distribution on the Chengdu and Wanzhou in Tang Dynasty.Three kinds of distributed types all should have the climatological indicative significance,but it is climate indicated the difference in the degree.Chengdu and Wanzhou Litchi＇s distribution has certain climatological indicative significance.The region microclimate is influenced by the big climate background change,only natural difference in the small region can be influenced by the atmospheric change.Therefore,in the upper Yangtze River the Litchi＇s distribution may indicate the climate.The historical climate research should set up macroscopic,the long time interval research angle of view,attach importance to the field inspection,emphasize the logical thinking,adopt the modern science and technology methods.
