在唐詩中，杜甫有許多獨特的表現，善用天象節氣入詩，是其中最有趣的作法之一。發現杜甫這項特色，並且把它作為注杜依據的，宋人黃鶴是不可忽略的先覺者。可惜黃鶴沒有正確的唐代曆法知識，他的立意雖好，實際指出的日期與節氣卻無一可用。本文將以六個事例，分為六個小節，各自解決一至二首詩的問題，將杜甫詩的節氣運用對於編年及詮釋的價值，簡要的呈現給讀者。

Making good use of jieqi (solar terms) is one of Du Fu's poems' unique characteristics mong the Tang poems. It is Huang He, a Song literati who can not be overlooked, found this characteristic on which he based the interpretation of Du Fu's poems. Unfortunately, he paid oblivious attention to the solar terms, which rendered senseless his pointing out the dates and the solar terms despite his good argument. This paper, by exemplifing six cases in six sections，each one of them attempts one or two problems of poems, in order to lay bare the meaningful use of solar to the chronicles and interpretation of Du Fu's poems.
