This paper presents some preliminary results of research on vegetation status in Tan Trao historical area, Tuyen Quang province. The results show that the vegetation in the relics are classified into 11 subformations of 7 formations, including: (1) Tropical rainforest closed evergreen closed forest in low and lowland terrain; (2) Low montane tropical rainforest closed forest on limestone; (3) Rainforest in low and lowland terrain; (4) Mainly tropical evergreen broad-leaved lowland and lowland grassland; (5) Tropical tall grassland with trees; (6) Grassy lowland grassland with shrubs, no trees; (7) Non-tropical dry grassland with no trees. Of which, tropical lowland rainforest populations in low and lowland terraces have two subformations: (i) Lowland evergreen broad-leaved lowland and lowland forest, (ii) The evergreen broad-leaved lowland forest in low and lowland areas is heavily impacted; The lowland montane rainforest closed tropical evergreen closed forest complex, has one subformation: (iii) Lowland evergreen broad-leaved lowland forest on limestone; Rainforest in low and lowland terrain, with four subformations: (iv) Evergreen broad-leaved lowland forest after swidden fields, (v) Tropical bamboo forest at low and low mountainous terrain; (vi) Tropical palm forests in low and lowland terrains; (vii) Evergreen broad-leaved lowland forest in low and lowland limestone; Most of the tropical evergreen broad-leaved lowland massifs are lowland and lowland, with two subformations: (viii) The primary evergreen broadleaved dipterocarp tree, (ix) Primary evergreen broadleaved scrub without spiky dipterocarp trees; The high grassland grassland with or without trees, has one subformation: (x) Tropical tall grassland with trees; The grassland group is not tropical highland species without trees, there are one subformation: (xi) Communiti of Musa sp.
