摘 要

 语言是动态的，随着语言的发展，系统功能语法也需要不断地构建和完善。
 语料库语言学和系统功能语言学是相辅相成的。语料库为语言学理论提供研究方法，同时，语料库语言学也开始更多地关注在语料库中所发现的大量的语言事实后面隐藏着的语言理论问题。语料库并非一堆任意组合而成的电子文本。它的建构必须具有一定的语言学理论基础，才能被称为语料库。因为语料库所试图表征的是语言的应用实际，因此韩礼德的系统功能语言学理论是一种较好地可以作为语料库建构的理论基础。近年来，系统功能语言学愈来愈多地开始关注语言分析的定量方法。系统理论是一个需要定量分析的概率系统，韩礼德引进概率这一概念，极大地丰富了系统语法的理论体系。而语料库的不断充实与完善为定量分析提供了可能性。韩礼德高度重视数学方法对于语言形式化研究的作用。他采用概率论有效地表征了语言系统及其选择，丰富并发展了系统语法的理论体系。目前，一种重要的趋势是充分利用各种语料库资源。
本文将着重研究语料库语言学与系统功能语言学之间的联系及二者之间的相互影响及作用，尤其是其通过概率这一重要媒介，二者如何完善和改进。

Abstract

Language is a dynamic system. Therefore, with the development of language, the Systemic Functional Linguistics (SFL) and Corpus Linguistics (CL) also need to be amended and improved constantly.
Corpus Linguistics (CL) and SFL are complementary to each other. SFL needs CL to provide a methodology for language study, and at the same time, CL itself begins to pay more and more attention to a theory system hiding in the massive language facts found in corpus. Corpus is not simply a text that is made up of piles of arbitrary language materials. The construction of corpus should be based on some certain linguistic theories, otherwise, it cannot be called corpus. As what corpus presents are the practical applications of language, Halliday's SFL theory is a comparatively good foundation for the construction of corpus. He used probability to present effectively the language system and its choice, thus enriched and developed the theoretical system of SFL. A nowadays important tendency is to make the most of multifarious corpus sources to embed the language system. In recent years, SFL has more and more concerned with quantitative methods in language analysis. SFL is a probabilistic system that requires quantitative analysis. Halliday's incorporating of the notion of probability has greatly enriched the theoretical system of SFL.
This paper will mainly discuss connections between CL and SFL, and the influences and functions to each other, especially how they get improved and perfected through the important medium-probability.
