摘　　要：本文基于704名大学毕业生的问卷调查结果,结合决策树模型分析法和传统单因素分析法,提取并分析了影响外语磨蚀的主要因素,得出如下结论:(1)除已明确的七大影响因素(磨蚀前水平、磨蚀时间、外语接触量、年龄、外语学习方式、情感因素、读写能力)外,性别也是影响外语磨蚀的因素之一。男性相对磨蚀程度低于女性;(2)在影响外语磨蚀的八个因素中,主要因素是磨蚀时间、磨蚀前水平和外语接触量;(3)易蚀人群的特征是:所占比例不大,其磨蚀前外语水平也超过国际通用外语基本目标水平的要求,但与外语接触极少或不接触,在4-8年敏感期内的相对外语磨蚀程度非常大。On the basis of the data obtained from a questionnaire investigating 704 college graduates,principal factors affecting foreign language attrition were extracted and analyzed with Decision-Tree Model and Single-Factor-A-nalysis Method.The following conclusions were derived:(1)Eight factors are identified in affecting foreign lan-guage attrition,that is,proficiency level prior to attrition,time since onset of attrition,and exposure to target language,age at onset of language attrition,foreign language instruction,affective factors,literacy,and gender.Gender is a factor retrieved for the first time in this study area.(2)Only three out of these eight factors are ex-tracted as principal factors:proficiency level prior to attrition,time since onset of attrition,exposure to target language.(3)College graduates prone to foreign language attrition are found to share some traits:these subjects are few in number;they have quite low or even no contact with target language,although their proficiency level prior to attrition used to be above the international basic requirements set for foreign language learners;their re-lative attrition is severe within the sensitive period of 4-8 years.
