Investigating Ecolinguistics within the Stratification-Instantiation Matrix of Systemic Functional Linguistics
From a systemic functional perspective,this paper investigates the disciplinary nature,approaches,research subjects,and contents of ecolinguistics.A brief review of the discipline and a few comments on it are first provided.Then,the elements involved in ecolinguistics are reexamined within the stratification-instantiation matrix of the social semiotic system.It is concluded that these two dimensions can provide a reference system for the elements of ecolinguistics,which is defined as a kind of"appliable linguistics",with the"appliability"of systemic functional linguistics being extended in its breadth and depth.
