历来谈论杜甫诗风诗旨,最多的便是沉郁顿挫、忧国忧民,然而考察其早年诗作,并非向来如此。在杜甫一生的诗歌创作中,诗风是不断嬗变的,变是常态。杜诗之所以形成沉郁顿挫的主导风格,具有深刻复杂的多重原因,诗人的遭际、境遇和所处的时代等,都起到了重要而微妙的作用。譬如杜甫在长安的十年,特别是天宝六载(747)参加李林甫主导的制举的经历,既是他人生的一大转关,在诗人的创作历程中也显得十分紧要。以天宝六载为分界点,考察杜甫十年间的作品,可知其诗歌在情事、诗艺、风格等方面都呈现出不易察觉的微妙变化,而诸多变化对于诗人锻炼、塑造深沉婉折的诗风,干系重大。天宝六载,既是杜甫的人生转折,杜诗亦从这里转折。论文还对李林甫与杜甫的关系提出了新的观点。 Du Fu has always talked about the poetic poetic purposes, the most is frustrated, worry about the people, but to examine his early poetry, this has not always been the case. In Du Fu’s poetry writing, poetic style is constantly evolving, change is the norm. The reason why Du Fu’s poems form a predominantly gloomy and dominant style has profound and complex multiple causes. The poet’s interpersonal conditions, circumstances and times are all important and delicate functions. For example, Du Fu’s ten years in Chang’an, especially the six-day Tianbao (747) participation in the Li Lingfu-led experience, is not only a major transition in his life, but also appears to be very important in his poet’s creation. Taking Tianbao 6 as the cut-off point and examining the works of Du Fu for 10 years, we can see that his poems show subtle changes that are not easily noticeable in the aspects of emotion, poetic art and style, and many changes poet’s style of exercise, Serious. Tianbao six set, both Du Fu’s turning point in life, Du Fu also turned from here. The paper also put forward a new view on the relationship between Li Linfu and Du Fu.
