红皮云杉(Picea koraiensis Nakai)是亚寒带的针叶树种,也是第三纪古老的稀有种、自然分布区仅限于东亚。我国东北长白山、小兴安岭林区,常见红皮云杉与红松、鱼鳞松、臭冷杉混交生长;大兴安岭北坡呼玛河、阿穆河水系河谷沿岸有少量分布。在内蒙古自治区昭乌达盟克旗白音敖包(蒙语:美丽的山头)沙丘上,却分布有大面积的红皮云杉天然原始林。这片沙地红皮云杉林,在国内、外均属罕见,对于研究我国东北西部、内蒙东部草原地带的森林资源与森林发生发展规律,以及“三北”地区沙地生态条件等方面都有重要价值。为了查明固定沙丘红皮云杉森林群落的结构与森林生产力;探讨红皮云杉异龄、复层结构的常绿针叶林的生物量及其分配情况,我们在1978—1979年做了沙地红皮云杉森林群落综合调查研究,本项研究是其中的一部分。
Picea koraiensis Nakai is a coniferous species of the sub-tropical zone, which is also an ancient rare species of Tertiary. Its natural distribution is limited to East Asia. In our country, Changbai Mountain and Xiaoxing’anling forests in northeastern China, common red pine and Pinus koraiensis, Pinus sylvestris var. Mongolica and Fir fir are mixed and grown. There is a small amount of distribution along the banks of the Huma and Amu rivers in the northern slope of Daxinganling. In Inner Mongolia Autonomous Region Zhaowuda Meng Keqi Baiyin obo (Mongolian: beautiful hill) dunes, but there is a large area of red spruce distribution of natural forests. This piece of sandy red-spruce forest, both at home and abroad are rare, for the study of the development of forest resources and forests in the western part of northeast China, Inner Mongolia grassland zone and the ecological conditions of sandy land in the “Three North” Have important value. In order to ascertain the structure and forest productivity of Phyllostachys pubescens community in a fixed sand dune, we discussed the biomass and its distribution of evergreen coniferous forests with different age and structure of the red-cedar spruce, which we did in 1978-1979 This study is part of a comprehensive survey of the sandy spruce forest community.
