英文摘要：

Ecolinguistics, also called ecology of language, is a new discipline combined by eco-science and linguistics. The Daling Zhuang dialect, one southern dialect of the Zhuang language, and the Daxin Cantonese, one dialect of the Han Cantonese, coexist in one ecological language environment. The paper probes into the existence and variation of the Daling Zhuang dialect and their causes in the perspective of ecolinguistics.
