Social and cultural factor is critical to the language variation.From the perspective of cultural ecology, language varia-tion interacts with cultural and ecological environment.The cultural pursuing of Chinese modernization and the globalization of ex-ternal English generate a special Chinese language variation-Chinese alphabetic words, whose further development may have reac-tion on Chinese cultural and ecological environment, bringing about positive and negative ecological impact.%社会文化因素是导致语言产生变异的重要原因之一。从文化生态的视角来看，语言变异与文化生态环境是互相作用的。汉语现代化的文化诉求和外部英语的全球化扩张催生了字母词这种特殊的汉语语言变异。其在汉语中的进一步发展又可能反作用于汉语文化生态环境，带来积极与消极的双重生态性影响。
