Based on fieldwork data,this paper represents the contexts of Wa language acquisition and use,and analy-ses the impacts of the National Bilingual Education Policy on the ecology of the Wa language,attitudes and its implication of cultural politics. We argue that rapid changing Wa language ecology,its shrinking register and function are caused not only by bilingual education and the strong influence of Mandarin,but also by rapid economic development,migration,and the self-awareness and subjectivity of the Wa.%双语教育对佤族的语言生态环境和语言态度的影响是透视当地文化政治的有效途径；导致佤语语言生态环境剧变、佤语语域萎缩和单语化倾向的根源不仅有双语教育政策的实施和汉语的强大语势，还有经济的快速发展、社会转型、人口流动及佤族自身的民族意识和主体性等因素。为受教育者提供双语学习的语言环境和选择权，使他们掌握社会所必需的工具、知识和技能，既要着眼于学校和家庭，又要超越学校和家庭，而不是孤立、生硬地传承某种语言文字本身。
