  • This study examined the relationship between the number of forest fires and days with no rainfall based on the national forest fire statistics data of the Korea Forest Service and meteorological data from the Open MET Data Portal of the Korea Meteorological Administration (KMA; data.kma.go.kr) for the last 30 years (1991-2021). As for the trend in precipitation amount and non-rainfall days, the rainfall and the days with rainfall decreased in 2010 compared to those in 1990s. In terms of the number of forest fires that occurred in February-May accounted for 75% of the total number of forest fires, followed by 29% in April and 25% in March. In 2000s, the total number of forest fires was 5,226, indicating the highest forest fire activity. To analyze the relationship between regional distribution of non-rainfall periods (days) and number of forest fires, the non-rainfall period was categorized into five groups (0 days, 1-10 days, 11-20 days, 21-30 days, and 31 days or longer). During the spring fire danger season, the number of forest fires was the largest when the non-rainfall period was 11-20 days; during the autumn fire precaution period, the number of forest fires was the largest when the non-rainfall period was 1-10 days, 11-20 days, and 21-30 days, showing differences in the duration of forest fire occurrence by region. The 30-year trend indicated that large forest fires occurred only between February and May, and in terms of the relationship with the non-rainfall period groups, large fires occurred when the non-rainfall period was 1-10 days. This signifies that in spring season, the dry period continued throughout the country, indicating that even a short duration of consecutive non-rainfall days poses a high risk of large forest fires.

  • Forest fires have potentials to change the structure and function of forest ecosystems and significantly influence on atmosphere and biogeochemical cycles. Forest fire also affects the quality of public benefits such as carbon sequestration, soil fertility, grazing value, biodiversity, or tourism. The prediction of fire occurrence and its spread is critical to the forest managers for allocating resources and developing the forest fire danger rating system. Most of fires were human-caused fires in Korea, but meteorological factors are also big contributors to fire behaviors and its spread. Thus, meteorological factors as well as social factors were considered in the fire danger rating systems. A total of 298 forest fires occurred during the fall season from 2002 to 2006 in South Korea were considered for developing a logistic model of forest fire occurrence. The results of statistical analysis show that only effective humidity and temperature significantly affected the logistic models (p<0.05). The results of ROC curve analysis showed that the probability of randomly selected fires ranges from 0.739 to 0.876, which represent a relatively high accuracy of the developed model. These findings would be necessary for the policy makers in South Korea for the prevention of forest fires.

  • In recent years, the number of cases caused by people such as forest fires has been increasing, so it is very important for the whole nation to prevent and practice forest fires. In addition, due to climate change around the world, many lives and disaster losses are increasing due to forest fire-related disasters, and in the last 10 years (2014-2023), there have been 5,668 forest fires and 40,037 hectares of damage, which is equivalent to 56,000 football fields, resulting in 19 casualties and 285.4 billion won in damages. Now, in order to improve the understanding and awareness of forest fires among all the people, the government should actively inform the people about how to act in the event of a forest fire by making the people's action tips related to forest fires easy to understand and practical through public relations activities. In addition, the public and the government should work together to prevent and prepare for forest fires before they occur.

  • 산불 발생에 대한 방지 대책을 수립하기 위해서는 과거 산불 자료의 특성을 분석할 필요가 있다. 본 연구는 1975년부터 2010년까지의 우리나라 산불 통계자료를 근거로 30 ha 이상 산불 피해의 분포 및 특성을 분석하였다. 그 결과, 30 ha 이상 산불 피해의 발생건수는 1978년에 23건으로 가장 많았으며, 1970 년대 이후부터 2000년대 들어서서 산불은 증가하는 추세에 있다. 주로 30 ha~50 ha의 규모 정도의 산불이 가장 많이 발생하였으며, 강원 지역의 산불이 총 66건(37.0 %)으로 가장 많이 발생하였고 점밀도 분석 결과로는 강원 지역이 우세하게 나타났다. 30 ha 이상 산불 피해는 4월에 발생건수가 114건(63.0 %)으로 가장 높았으며, 일요일에 44건(24.3 %)으로 가장 많이 발생하였다. 1975년 이후로 산불 발생 건수와 피해액이 점점 증가하는 추세에 있어 산불관련 기관에서 본 연구 결과를 바탕으로 산불방지 정책 수립에 효과적으로 사용할 수 있을 것이다.

  • Fire, being primarily a natural phenomenon, is impossible to control, although it is feasible to map the forest fire risk zone, minimizing the frequency of fires. The spread of a fire starting in any stand in a forest can be predicted, given the burning conditions. The natural cover of the land and the safety of the population may be threatened by the spread of forest fires; thus, the prevention of fire damage requires early discovery. Satellite data and geographic information system (GIS) can be used effectively to combine different forest-fire-causing factors for mapping the forest fire risk zone. This study mainly focuses on mapping forest fire risk in the Madikhola watershed. The primary causes of forest fires appear to be human negligence, uncontrolled fire in nearby forests and agricultural regions, and fire for pastoral purposes which were used to evaluate and assign risk values to the mapping process. The majority of fires, according to MODIS events, occurred from December to April, with March recording the highest occurrences. The Risk Zonation Map, which was prepared using LULC, Forest Type, Slope, Aspect, Elevation, Road Proximity, and Proximity to Water Bodies, showed that a High Fire Risk Zone comprised 29% of the Total Watershed Area, followed by a Moderate Risk Zone, covering 37% of the total area. The derived map products are helpful to local forest managers to minimize fire risks within the forests and take proper responses when fires break out. This study further recommends including the fuel factor and other fire-contributing factors to derive a higher resolution of the fire risk map.

  • 산불은 대부분 인위적인 원인에 의해 발생되지만, 산불의 피해가 대규모로 확산하는 연소 조건은 자연현상에 의해 영향을 받게 된다. 본 연구에서는 여러 인자 사이의 의존 및 인과관계를 분석할 수 있는 부분최소제곱 구조방정식 모형(PLS-SEM)을 이용하여 기상 및 가뭄이 산불 발생에 미치는 인과관계와 영향 정도를 평가하였다. 그 결과 지난 2015년부터 약 5년 기간 동안 발생한 강원도 산불에 미치는 가뭄의 영향은 27 %, 기상학적 영향은 38 %로 확인되었다. 또한, 강원도에서 발생한 산불 중에서 봄철에 발생한 산불은 약 60 %의 비율을 차지하며, 이는 기상학적 요인과 더불어 이전 연도의 가을과 겨울철 가뭄이 산불 발생에 영향을 미치는 것으로 해석된다. 산불 발생위험을 평가하는 데 있어 극심한 기상학적 가뭄이 가을과 겨울철에 발생했다면, 이듬해 봄에는 산불의 발생확률은 증가할 가능성이 있다.

  • Gunung Gede Pangrango National Park is one of the Long-term Ecological Research Site in Indonesia. In the late 1997, the fires have burnt and destroyed nearly 300 ha forest in this park. and G. Masigit was the largest burnt area (250 ha) of nine locations of hot spot recognized. Undergrowth vegetation got the most severe impacts. Almost undergrowth vegetation in various location were totally burnt. However, within three months following burning new seedlings such as Omalanthus populneus, Macaranga, Trema orientalis and Eupatorium appeared in the forest floor- The number of mycoflora recorded in burnt forest was interestingly increased in post forest fires site. Forest fires in G. Masigit had also affected the wild life population and diversity. For example, the number of bird species and the number of soil insects in burnt forest was significantly reduced. The forest fires had also great impact on soil. such as on soil organic contents, bulk density, colour, consistency, permeability and the activity of soil microorganisms.

  • Understanding regional characteristics in forest fire occurrence is important to establish effective forest fire prevention policy in Korea. This study analyzed the characteristics of forest fires occurred in 16 administrative districts for recent 25 years (1990~2014) to examine regional characteristics in forest fire occurrence. Forest fire occurrence reflects regional characteristics depending on climatic factors as well as region's society-cultural factors. Results showed that the first cause of forest fire occurrence was carelessness by human activities throughout all administrative districts, however, the second cause depends on regional characteristics. As the results of forest fire occurrence period analyzed for 10 days, the most forest fires occurred in the southern region during January to March, while forest fires in the northern region occurred mostly during March to April. We classified forest fire occurrence patterns into three types (centralized: Gyeonggi-do, dispersal: Busan, horizontally distributed: Gyeongsangnam-do) by multi-temporal analysis for forest fire occurrence period.
