Abstract: Khorchin Grassland has the feature of recording Duanmu Hongliang's self-narration of his clan history， but there are also many clan materials that have been deleted and modified in the novel. Khorchin Grassland takes the “developing” of the Northeast grassland as the story strategy， and the Marxist materialism and national “fable” style of writing triggered the selection and rewriting of clan abilities in the novel. With the narrative representation of the protagonist's “growth”/“anti-growth”， there is a narrative mechanism to pursue the “primitive force” on the grassland. Studying the reconstruction of the ability of “Khorchin Grassland” displays the constant and change of enlightenment literature in the 1930s. There are many writing divisions when Duanmu manage the clan abilities， which also affected the status of the novel in the history of literature.

Key words: Khorchin Grassland; Duanmu Hongliang; clan novel; northeast writers; Ding Ning
