Abstract：The publish White Birch literature based on the Web of Science database were analyzed in the world from 2004 to 2014.The general trend，top 20 countries，research institutes，core authors，key journals，disciplines in the world were retrieved.The results indicated that a total of 554 White Birch literature was identified in the world.The literature number of White Birch increased year by year in the world.The number of White Birch literature in 2012 was the highest.The top 5 prolific countries were the Canada，United States，China，Finland and Germany.The literature number of White Birch was 193 in the Canada，which was higher than other countries.The top institutions with high academic achievement were Northeast Forestry University，University of Laval，University of QUEBEC，Chinese Academy of Sciences and Lakehead University.The core authors with high academic achievement were mainly from Canada. "Forest Ecology and Management"，"Canada Journal of Forest Research"，"Forestry Chronicle"，"Tree Physiology"，"Holzforschung"，"Northern Journal of Applied Forestry"，"Bioresources"were the most active journals in this field. The main disciplines of White Birch literature were Forestry，Environment Science，Material Science，Plant Science，Biochemistry&Molecular Biology and Agronomy.

白樺（Betula platyphylla），为桦树科、桦树属乔木，是荒山荒地、采伐迹地和火烧迹地的先锋树种，是温带阔叶林和阔叶混交林的主要树种，具有耐寒性强、适应性好、生长速度快等优点，是我国极为重要的山地造林。

白桦的纤维素含量高、纤维长度大、质地坚硬，是我国极为重要工业用材树种和速生山地造林树种；材质洁白，用途广泛，是胶合板、装饰板、牙签、卫生筷子、雪糕把的良好原料；树皮含油脂高，可取桦油，含单宁为11%左右，可提取拷胶；白桦汁液可开发饮料，现代研究还发现，白桦液还具有抗氧化、清除自由基和延缓衰老的特殊功效。此外，白桦树叶含三菇皂试、黄酮类、香豆素类和没食子酸等成分，不仅可用作利尿剂，而且具溶血作用[1-5]。
