China is not rich in natural forest sources. Owing to natural and historical factors, forest fires have long been frequenting China. Forest fire prevention is the most important of all. Forest fire prevention and controlling have long been held as a very important factor in our ecological plans. Taking china 's special geographical location, topography, climate and the distribution of forest sources into consideration, we have every reason to believe that forest fires in China have their own special environment and occurrence. China suffers forest fire hazards heavily. Forest fires arise occasionally from thunderstruck or self-burning of peat. However, most fires are due to man's fault while inappropriately using fires in production and daily life. Since China is located in the Northern Hemisphere with a vast territory, there is a striking difference in the climate between South China and North China.  相似文献

The history of forest fires was studied in north-west Russia near the Finnish-Russian border on a total of 22 transects within a 3 x 4 km area, 100 m long and 20 m wide, bydendrochronological methods. In total, 25 fires were identified as having occurred in the area between 1400 and 1998. On average, a fire occurred somewhere within the area once every 23 yrs, and once every 13 yrs between 1650 and 1950. The fire frequency (proportion of the area burnt per time unit) broadly followed the changes in the number of fires, but there were also differences. The fire frequency was 1.87% from 1679 to 1872 and 0.40% from 1873 onwards. The mean fire interval was 62 yrs and the median interval 56 yrs. According to the tree-ring width chronology tree growth was significantly lower in the dated fire years than in other years. Forest fire history in north-west Russia is broadly similar to that in many parts of Scandinavia.  相似文献

森林火险等级预报系统评述   总被引:22,自引:1,他引:21  
对当前世界上主要的森林火险等级系统进行了综述, 包括加拿大、美国、澳大利亚以及其他一些国家的森林火险等级系统。对主要森林火险等级系统的组成、结构和发展过程进行了比较, 讨论了这些系统应用的局限性。比较了世界上3个应用比较普遍的森林火险等级系统的发展、可燃物类型、输入因子、输出因子和应用范围, 认为发展中国的森林火险等级系统采用加拿大的森林火险等级系统(CFFDRS)的技术比较合适。我们可直接应用CFFDRS, 然后根据当地气候和可燃物类型对火险等级系统进行校正。  相似文献

Based on the fire statistics, the Daxing’anling forest area were classified into three fire cycle regions: northern coniferous virgin forest region with a fire cycle ofl 10–120 years, middle conifer-broad-leaved mixed forest region with a fire cycle of 30–40 years, and southern broad-leaved secondary forest region with a fire cycle of 15–20. The percentage of conifers and broad-leaved trees, forest age and natural mature period of main tree species in different fire cycle regions were discussed in concern with fire occurrence. The characteristics of fire adaptation and fire resistance of main tree species, such as sexual and asexual reproduction, were discussed and evaluation of the synthetical fire adaptation was made.  相似文献

Pine resistance to low- to moderate-intensity fire arises from traits (namely related to tissue insulation from heat) that enable tree survival. Predictive models of the likelihood of tree mortality after fire are quite valuable to assist decision-making after wildfire and to plan prescribed burning. Data and models pertaining to the survival of European pines following fire are reviewed. The type and quality of the current information on fire resistance of the various European species is quite variable. Data from low-intensity fire experiments or regimes is comparatively abundant for Pinus pinaster and Pinus sylvestris, while tree survival after wildfire has been modelled for Pinus pinea and Pinus halepensis. P. pinaster and P. pinea, and Pinus canariensis in special, are better equipped to survive fire, but low-intensity fire is tolerated even by species often referred to as fire-sensitive (P. halepensis and Pinus radiata). The relative fire resistance of European pine species is assessed on the basis of (i) morphological and experimental data, and (ii) mortality modelling that considers fire behaviour. Limitations of these approaches to rate fire resistance are discussed, and the current knowledge gaps are indicated.  相似文献
