汉字被认为是留学生，尤其是非汉字文化圈国家的留学生的最大难题。对于汉字的音形义文化背景的缺失，成为了表意文字——汉字的学习的重大阻碍。正是由于汉字学习对于这类学生而言很困难，所以产生了大量偏误，因此偏误分析研究就显得尤为重要。偏误分析是一种分析汉字习得中出现问题的根源的方法，这种分析和研究是针对留学生经常遇到的一些错误而进行的，巨有极强的针对性。基于语料库的分析，发现学生汉字偏误主要分为错字和别字。前者的偏误类型有笔画偏误和部件偏误。后者的偏误类型主要分为音同音近别字和字形相近别字。针对上述偏误，从中找出汉字偏误的成因，并提出相应的策略，帮助学生更好地学习汉字。

Chinese characters are considered to be the biggest problem for foreign students, especially those from non-Chinese cultural circle countries. The lack of cultural background for the sound, shape and meaning of Chinese characters has become a major obstacle to the study of ideographic characters-Chinese characters. It is precisely because the learning of Chinese characters is very difficult for such students, so there are a lot of errors, so error analysis and research is particularly important. Error analysis is a method to analyze the root of the problems in the acquisition of Chinese characters. This analysis and research is aimed at some errors that foreign students often encounter, which has a strong pertinence. Based on the analysis of the corpus, it is found that students' Chinese character errors are mainly divided into wrong characters and other characters. The error types of the former include stroke error and component error. The error types of the latter are mainly divided into homophones and similar glyphs. In view of the above errors, this paper finds out the causes of Chinese character errors and puts forward corresponding strategies to help students learn Chinese characters better.
