STUDY ON THE COMPOSITION AND CHARACTERISTICS OF FOREST FIRE FUELS AT DIFFERENT FOREST STATES IN DINH HOA DISTRICT, THAI NGUYEN PROVINCE

Abstract

The study determined the possibility of forest fire in 05 different forest types through the composition and characteristics of forest fuels. This study also proposed to forest fire season, composition and characteristics of forest fuels by common methods in forest study. The research results show that the forest fire season at the study site is from November of previous year to April of following year. The study also determined the growth status of the stands through the criteria D1.3 and Hvn, and the density, in which the poor natural forest has the highest D1.3 at 14.5 cm, the lowest in bamboo forest is 6.74 cm. The volume of forest fuels varies between forest states, specifically the mixed forest status Wood-Bamboo has the highest volume (8,915 tons/ha), the smallest is poor forest (5,631 tons/ha). The moisture content of bamboo forest fire fuels is the lowest (11.634%), the highest is the mixed wood-bamboo forest (22.485%), therefore, the probability of a bamboo forest fire is highest, because it has a coefficient of K = 0.93.
