This paper discusses the similarities between the digital education ecosystem and natural ecological ecotones, emphasizing fundamental characteristics of the digital education ecosystem such as its boundaryless and ever-changing nature, as well as its intersection with digital and educational ecosystems. It also elaborates on the similarities between the digital education ecosystem and the educational ecosystem, comparing their species exchange rates and diversity. The digital education ecosystem not only demonstrates a higher species exchange rate but also exhibits greater species diversity. Furthermore, the development of the digital education ecosystem relies on the joint participation of information technology enterprises and the education sector, alongside global governmental emphasis on educational informatization. Lastly, employing the theory of ecotones, the paper analyzes and explains some current issues in educational informatization, such as why certain teachers and students lack deep involvement in educational informatization.
