从西周气候的变迁看《豳风·七月》的写作时间

On the Writing Time of "Bin Wind,July" from the Weather Change in Xi Zhou Dynasty

西周前期是温热天气,到中叶气候转入寒冷干旱期。根据西周气候的变迁和《幽风.七月》一诗中的物候现象,以及文献考古材料,可以证明《幽风.七月》作成时间不是在周初,而应为西周中期偏早阶段。

In early Xi Zhou dynasty, it was warm and hot, while in middle period, it turned to be dry. According to the change of weather in Xi Zhou dynasty and the phenological phenomenon in the poem, and some relevant documental archaeological materials, the writing time of “Bin Wind, July” should be early middle Xi Zhou dynasty but not early Xi Zhou dynasty.
