The effects of forest fires on some ecosystems and succession process of burned site

由于缺乏对日本部分老旧火烧区火灾后植被演替的研究，有关火灾后植被演替的资料较少。在本州岛的北海道和东北地区，一些被烧毁的地区长期没有植树造林。1911年5月18日发生了一场大规模的森林大火，在北海道的富兰诺市周围，针阔混交林的原始植被被烧毁了约36公里。大部分被烧毁的地区都种上了针叶树(冷杉、落叶松、云杉等)。一些没有植树造林的火烧区生长着落叶阔叶树和灌木。蒙古桦树落叶阔叶树。Roseserrata、白桦Betula Biryphy lla var.林内乔木层以日本、元宝枫等为主，下层有冷杉、油杉等常绿针叶树种入侵。落叶阔叶林(阔叶林)未来将转变为针阔混交林。1983年4月27日，岩手县库集市发生森林火灾，烧毁面积约930公顷。烧毁锯缘栎树、蒙古栎林。罗汉果、板栗、安息香、红枫、山李等在烧焦的树干上大量萌发基梢，部分新梢在森林火灾后20年内存活下来。火烧后的灌木林植被与1984年调查的未烧毁的灌木林相似。

There is a little information about succession of post-Fire vegetation because of lack of study on some old burned areas following fire in Japan. Some burned areas remained without afforestation for a long time in Hokkaido Island and Tohoku District of Honshu Island.A large-scale forest fire started on May 18, 1911, and the original vegetation of mixed conifer-hardwood forest burned out approximately 36 Km^2 around Furano city in Hokkaido. Most of the burned area have been planted some coniferous trees (fir, larch, spruce etc.) and deciduous broad-leaved trees and shrubs grew in some burned area without afforestation. Deciduous broad-leaved trees of Betula maximowicziana, Quercus mongolica var. grosseserrata, Betula platyphylla var. japonica, Acer mono and so on dominated in the canopy tree layer in the forest and evergreen coniferous trees of Abies sachalinessis and Picea glehnii invaded in the substrata. Deciduous broad-leaved forest (hardwood forest) will change to mixed conifer-hardwood forest in the future.The forest fire burned out about 930 ha on April 27, 1983 in Kuji city, Iwate Prefecture. Burned canopy trees of Quercus serrata, Quercus mongolica var. grosseserrata, Castanea crenata, Styrax obassia, Acer rufinerve, Prunus verecunda and so on put out a large number of basal shoots on their scorched trunks and some of new shoots survived in twenty years after the forest fire. The post-fire vegetation of burned coppice forest is similar to unburned coppice forest investigated in 1984.
