五律→七古→五古→七律：杜甫诗体流变探微

摘要

杜甫众体皆长,但在不同的发展阶段,也有自己特别中意或者特别用力的主打诗体。早期以当时盛行的五言律诗为主,困守长安和安史之乱时期主要创作具有强烈现实主义精神的歌行,漂泊西南时期则倾力于七言律诗的诗律探讨,并最终使七律走向了成熟。五律→七古→五古→七律,是杜甫诗体流变的轨迹。%Du Fu was good at various styles of poems,though he had his own preference for particular main styles in different times.In his early days he mainly wrote five-character poems which prevailed at that time;during the siege of Chang＇an and Anshi Rebellion,he mainly wrote realistic poems;while wandering in the southwest,he was devoted to the research and writing of seven-character poems,and finally helped it fully developed.From Wulv to Qigu to Wugu to Qilv is the way of change of Du Fu＇s poems.
