This paper focuses on the nativization of English in China, using Pidgin English as a case study to put Chinese English variants under the theoretical framework of eco-linguistics, and put the ecological environment such as species competition, coexistence and co-evolution, etc. The natural phenomenon is compared with the existence of language phenomenon in the development process of China English represented by Pidgin English.The study found that as the spark of the collision of the two mainstream languages of Chinese and English, the Chinese English varieties play a very important role in the exchange and enrichment of the two languages and cultures. Although academic circles have different attitudes and opinions on Chinese English variants, their existence and development conform to the law of the development of things and are also inevitable in historical development. Blindly ignoring their objective existence will definitely bring adverse effects on the ecological balance of the language. We should face up to the existence of Chinese English variants, comply with the law of language development, and allow it to develop naturally, and make efforts to protect the ecological balance of the world’s languages.
