黄庭坚对于古、律两体的处理在宋代诗人中有着鲜明的特色。本文从黄庭坚古体与近体的声律修辞、体制特点以及表现功能等方面入手考察了其古、律融合的创作现象，进一步阐释其诗歌破体互参现象背后的体制思想与诗学主张，并探讨了黄庭坚古、律兼重的诗学态度对宋代诗学所产生的影响。纵观宋代文学的发展，“备众体”观念一直为宋代文人所追捧，而黄庭坚正是在兼备众体这一诗学道路上走得最远的诗家。山谷的五言八句体古诗写作广泛借鉴律诗体制，将律诗的声律对偶融入古体写作。在体制形态上，黄庭坚以律入古的诗歌与齐梁体以及初、盛唐间介乎古、近体之间的五言八句体十分相似。内容上，山谷则进一步上溯汉魏，将汉魏诗的高格调与近体格律相结合，创造出极具特色的短篇古诗。律体创作上，山谷继承杜甫七律变调，将古诗的声律特点、审美趣味以及创作精神融入律诗写作，并在杜甫基础上更为彻底地打破了格律的束缚。黄庭坚及江西诗派诸人大量的拗体创作及理论总结也进一步消解了律诗体制。山谷对于古、律两体关系的处理，必然受其文体思想的影响。在其大量古、律融合诗作的背后，暗含着黄庭坚诗学思想的演变。早年的黄庭坚主张尚锻炼、重法度，其体制思想中蕴含着从“破体制”到“备体制”再到“自成一家”的诗学逻辑。山谷晚年则更追求自然平淡的浑成诗风，其晚期古、律融合的短篇诗歌正是“无意为诗”观念的体现。黄庭坚古、律兼重的诗学态度，在纠正了古文诗派以文为诗的同时，也促使宋代的诗学立场由古体向近体转变。南宋律诗创作的蔚然成风、宋末崇律观念的兴起以及元代诗学理论的兴盛，都与黄庭坚的诗学观念有着或隐或显的联系。
