The multiple niches of College English teachers and students determine their multiple identities. At the same time, because each niche has the potential of unlimited expansion, each identity of teachers and students also shows different vitality. The application of network technology has become the main factor affecting public English education, which breaks the balance of traditional college English education ecosystem. It is the main means to improve the quality of College English teaching to construct the ecological environment of English education by using network big data technology. Based on the principle of educational ecology, this paper analyses the relationship between the factors in College English education by using big data mining technology. This paper constructs an educational ecosystem oriented to adaptive balance adjustment.
