Abstract:
|
The Voi Mep massif of the Truong Son range, having the highest peak in the
Quang Tri area (1739m), is composed of granite and granodiorite intrusive rocks in Ben
Giang-Que Son complex. This massif is fairly isometric with characteristic landforms
comprising: remnants of old pediment surfaces, mountain slopes and valleys with steep
profiles. The massif area has a regular altitudinal differentiation manifested in the formation
of two climatic belts: tropical humid climatic belt, subtropical humid climatic belt; two
altitudinal soil belts: red yellow soil belt and red yellow humus soil belt; four altitudinal
vegetation cover types: evergreen broadleaf closed forest, mixed broadleaf/needleleaf
forest, needleleaf forest and association of Arundinaria sat. The combination and interaction
of natural components led to the formation of two altitudinal landscape belts: mountain foot
tropical landscape belt and medium montane subtropical landscape belt. |
