俄罗斯最近的火灾管理政策假定将火灾完全排除在法定储备之外。我们分析了自然，气候引起的火灾制度的历史年份1901年至1998年在俄罗斯，在俄罗斯的生物多样性热点，并在选定的法定保护区，如果人类的影响被忽视。一个全球动态植被模型与合并的全球统计火灾模块被用来重建火灾历史的潜在植被。我们通过比较1947-1998年期间燃烧的模拟区域与俄罗斯的可用火灾统计数据，证明了火灾模块的可行性。分析火灾制度在俄罗斯的三个生物多样性热点北高加索，南西伯利亚和远东地区，并在这些热点内的代表性保护区，包括相互比较的区域面积烧毁，1901年至1998年期间的归一化，区域平均和最大火灾规模。我们发现，俄罗斯生物多样性丰富的大面积区域与火灾频繁的区域自然重合，而这些区域的大小也存在很大差异。热点地区相当大的空间气候和植被变化影响了区域保护区的自然火灾状况，使大陆自然保护区最容易发生火灾。我们建议，在俄罗斯大型保护区的火灾管理计划，应调整根据自然地理格局的火灾制度在该国的保护政策。
Recent fire management policy in Russia assumes the complete exclusion of fires from the statutory reserves. We analyzed what the natural, climate-induced fire regimes for the historical years 1901–1998 in Russia, in the Russian biodiversity hotspots and in the selected statutory reserves would be if the human impacts were neglected. A global dynamic vegetation model with an incorporated global statistical fire module was used to reconstruct a fire history for potential vegetation. We demonstrated the feasibility of the fire module by comparison of the simulated area burnt for the period 1947–1998 with available fire statistics from Russia. Analysis of fire regimes in the three Russian biodiversity hotspots North Caucasus, South Siberia, and the Far East, and in representative protected areas within these hotspots, included inter-comparison of regional areas burnt, normalized for the period 1901–1998, and regional average and maximum fire sizes. We showed that large-scale areas of rich biodiversity in Russia coincide naturally with areas of frequent fires, which in turn are also highly variable in size. Considerable spatial climatic and vegetation variation in the hotspots influence the natural fire regimes of regional protected areas, making continental nature reserves the most fire-prone. We suggest that the fire management plans of large reserves in Russia should be adjusted according to the natural geographic pattern of fire regimes in the country for benefit of conservation policy.
