Currently, the assessment of the appropriateness of the forest fire forecasting methods being applied in localities of Vietnam, including Quang Ninh province is very necessary. This research applied some study methods, namely desk research based on the published materials and specialized surveys on the characteristics of forest structure, fuel characteristics and meteorological condition on 09 typical sample plots of the forest stands including Pinus massoniana Lamb (6-7 years and 29-30 years old) and Acacia auriculifonnis x Acacia mangium (4-5 years old) in Hoanh Bo district:. in combination with using the mathematical statistics in order to determine the relationship between fuel moisture, rate of spread and number of forest fires with indicators reflecting the risk of forest fires. The study shows that, in the recent ten years, forest fires occur at all forecasted levels classified by both methods currently being applied in the region. Around 50 percent of forest fires occur during the days which have high fire risk (in levels IV and V), but also 27.0 percent to 28.4 percent of the fires occurred in the levels I and II. The determination of the'forest fire risk using the P index in Hoanh Bo district implemented in Forest Protection Agency of Region I is fairly appropriate. However, the forecast results have higher accuracy level when was used the P7 index with Ki = (7 - Ri)/7 (Ri is the rainfall at the day i). Based on the research findings, this study posed some recommendations in order to improve the accuracy level of forest fire forecast in Hoanh Bo district, Quang Ninh province.
