北宋儒学与佛教之关系是学界颇为关注的问题之一，二者在推动各自演变的同时又相互碰撞。欧阳修作为北宋儒者的代表性人物，他一面力主排佛，对佛教多有批评，另一面又与佛教有着千丝万缕的联系，这也就使其与佛教的关系稍显复杂。面对儒学日渐式微佛教日益兴盛的局面，欧阳修以复兴儒学为己任，在前代辟佛经验的基础上试图从儒家学说当中寻找战胜佛教的方法，这一探讨辟佛之方的路径也为后来者所承接并加以发挥，由此可见其辟佛思想举足轻重之地位。因而对欧阳修辟佛思想分析研究的重点就不能仅局限于论述欧阳修是如何辟佛，还需要探讨其辟佛思想有什么意义。故本文尝试以欧阳修的诗文为主要研讨文献来论述其辟佛思想，按照他是如何看待佛教、为何会排斥佛教、对佛教的具体批判之处是什么以及他对佛教的批判有何意义这一思路展开并试着对这些问题予以阐释，先是细致讨论欧阳修对于佛教的态度、认知与批判，进而总结欧阳修辟佛思想所具有的突出的特点及其局限之处并探讨其辟佛思想所具有的意义。欧阳修有着明确自觉的儒者身份立场，他以三王之治为政治理想目标，因而对佛教持排斥否定之态度，故他视佛教为世之大患、佛法为奸邪之说，并揭示佛教具有危害国家、祸及百姓、威胁儒学之正统地位等弊害从而阻碍王道政治的实现。然而欧阳修又能理性地看待佛教，他并不排斥与僧侣往来，对佛教也有一定的了解，其理性的态度让他意识到有必要对佛教的发展状况及其昌盛原因加以分析，也正是基于这一分析，让他探索出了一条不同于以往的辟佛之方。也就是说欧阳修不主张与佛教展开激烈对抗而是通过加强自身建设来抵御异说，这种迂缓之方亦受到了后之儒者的推崇，后来者在充分挖掘儒学之思想资源的基础上又有着自己的发挥从而进一步丰富和发展了儒家学说，使得儒学再度获得新生。虽然欧阳修辟佛思想还存在一定的局限性，其思想的深刻性也受到后之儒者的猛烈批评，但我们还是要看到其思想所具有的独到之处及其对后来儒学新形态的形成与发展所起到的作用。

The relationship between Confucianism and Buddhism in the Northern Song is one of the issues that has attracted much attention in the scholarly world, as the two have driven their own evolution while at the same time colliding with each other. As a representative figure of Confucianism in the Northern Song, Ouyang Xiu was a strong advocate of the exclusion of Buddhism and a critic of it, but on the other hand he was inextricably linked to it, which makes his relationship with Buddhism slightly complicated. In the face of the decline of Confucianism and the rise of Buddhism, Ouyang Xiu took upon himself the task of reviving Confucianism and, on the basis of the experience of his predecessors, tried to find a way to overcome Buddhism through Confucianism, a path that was taken up and played out by later generations, thus demonstrating the importance of his thinking on the prevention of Buddhism. The focus of the analysis of Ouyang Xiu‘s thought on the prevention of Buddhism cannot be limited to a discussion of how Ouyang Xiu prevented Buddhism, but also what the significance of his thought on the prevention of Buddhism was. Therefore, this paper attempts to discuss Ouyang Xiu‘s thought on the repudiation of Buddhism, using his poetry and writings as the main documents for the study, following the ideas of how he viewed Buddhism, why he rejected Buddhism, what his specific criticisms of Buddhism were, and what the significance of his criticisms of Buddhism were. It then goes on to summarize the salient features and limitations of Ouyang Xiu‘s thought on the prevention of Buddhism and discusses the significance of his thought on the prevention of Buddhism.Ouyang Xiu had a clear and conscious Confucian stance, and as his political ideal was the rule of the three kings, he rejected Buddhism and regarded it as a great danger to the world and an evil doctrine. However, Ouyang Xiu was able to look at Buddhism rationally, he was not averse to interacting with monks, and he had a certain understanding of Buddhism. And his rational attitude made him realize that it was necessary to analyze the development of Buddhism and the reasons for its prosperity. It was on the basis of this analysis that he explored a different critical approach to Buddhism. In other words, Ouyang Xiu did not advocate a fierce confrontation with Buddhism, but rather strengthened himself to resist heresy, and this roundabout approach was also respected by later Confucians, who further enriched and developed Confucianism by fully exploiting its intellectual resources and making it new again. Although Ouyang Xiu‘s thought on the prevention of Buddhism still had certain limitations, and the profundity of his thought was heavily criticized by later Confucians, we still need to see the uniqueness of his thought and the role it played in the formation and development of the new form of Confucianism.
