摘　　要：在已探明的外语磨蚀影响因素中,只有情感因素对外语磨蚀的直接作用尚不明确。本文基于对704名大学毕业生的调查,运用结构方程模型分析情感因素对目标语接触量的影响路径和力度,并通过情感因素的分类,提取外语磨蚀群体的主要类别和"低目标语接触量"的群体特征。所得基本结论如下:1)随着时间的推移,情感因素基本保持稳定,目标语接触量会明显下降,好的情感因素可提升目标语接触量;2)"低目标语接触量"的群体特征为:人数比例小,对待目标语的语言态度表现为中性或偏消极,具备中性或偏弱融入性动机和极弱的工具性动机。Of all the factors proved to affect foreign language attrition,only the direct effects of affective factors are uncertain.To get a better understanding,the path and strength of affective factors on target language exposure were analyzed in this paper under Structural Equation Model on the basis of the data obtained from a questionnaire investigation among 704 college graduates.The main clusters in terms of affective factors and the traits of foreign language attritors having less exposure to target language were extracted through Decisive Tree Model.Following conclusions were derived：1）affective factors remain stable with time going by,while target language exposure has decreased significantly;positive affective factors help increase target language exposure;2）subjects who have less exposure to target language share some traits：they are few in number;they take a neutral or slightly negative attitude towards foreign language,and they have neutral or fairly weak integrative motivation and weak instrumental motivation.
