2017~2022年间国内汉语二语词汇习得述评
A Review of CSL Vocabulary Acquisition in China from 2017 to2022

词汇能力与听、说、读、写各项语言能力具有很强的相关性，对二语学习者有重要意义。21世纪以来，汉语二语词汇习得越来越受到国内外研究者的关注，并得到迅速发展。本文通过对2017~2022年国内6种汉语类专业期刊刊登的汉语二语词汇习得研究论文进行整理、统计和分析，发现：1) 近6年间，汉语二语词汇习得研究延续了21世纪初以来良好的发展势头，论文整体数量保持稳定并稳步上升，但论文数量整体基数仍然较小；2) 研究热点出现转移，学习者词汇特征不再是所有主题中占比最大的部分，词汇习得的内部因素和外部因素占比有所上升；3) 各研究主题间广度和深度的不平衡性进一步缩小，但各研究主题的占比仍然存在较大差异。心理词汇的认知加工机制、词汇广度和深度的测量、词汇习得的研究方法有待进一步拓展和深化。
Vocabulary skills have a strong correlation with all language skills of listening, speaking, reading and writing and are of great importance to second language learners. In the 21st century, Chinese second language (CSL) vocabulary acquisition has received more and more attention from domestic and foreign researchers and has been developing rapidly. By collating, counting and analyzing the research papers on CSL vocabulary acquisition published in six Chinese professional journals in China from 2017 to 2022, this paper finds that: 1) The research on CSL vocabulary acquisition has continued the good development momentum since the beginning of the 21st century in the past six years, and the overall number of papers has remained stable and steadily increased, but the overall base of the number of papers is still small; 2) The focus of research has shifted. Learner vocabulary features are no longer the largest part of all topics, and the proportion of internal and external factors in vocabulary acquisition has increased; 3) The imbalance of breadth and depth among research topics has further narrowed, but the proportion of each research topic still varies greatly. The mechanisms of cognitive processing of mental vocabulary, the measurement of vocabulary breadth and depth, and the methods of vocabulary acquisition research need to be further expanded and deepened.
