白桦是一个北温带的广布种 ,主要分布在温带亚洲的日本、朝鲜、俄罗斯和中国。白桦在我国分布于东北的大、小兴安岭和长白山 ,华北的燕山、太行山 ,西北的秦岭、天山、阿尔泰山 ,西南的横断山脉、青藏高原。白桦生长迅速 ,对环境的适应能力强 ,是恢复植被、保护森林水分和土壤的优良造林树种 ,白桦又是一个重要的药用和纤维用优良经济树种 ,因此 ,白桦资源具有全球范围内的广阔的发展前景。本文论述了中国白桦资源的地理分布、群落生态、生长发育、遗传生态、转基因技术和树皮、树叶、木材的加工利用 ,同时 ,还阐述了中国的白桦天然林保护工程、白桦工业的发展以及白桦资源的合理开发利用 Betula platyphylla is a north temperate broad species, mainly in temperate Asia, Japan, North Korea, Russia and China. White birch in China distributed in the Northeast, the Greater Xinguang and Changbai Mountains, North China’s Yanshan, Taihang Mountains, Northwest Qinling, Tianshan, Altai Mountains, southwest of the Hengduan Mountains, the Tibetan Plateau. Betula platyphylla grows rapidly and has strong adaptability to the environment. It is an excellent afforestation species for restoring vegetation, protecting forest water and soil. Betula platyphylla is also an important economic tree species for medicinal and fiber use. Therefore, Betula platyphylla resources have a wide range of global scope The development prospects. This paper discusses the geographical distribution of Chinese birch resources, community ecology, growth and development, genetic ecology, transgenic technology and bark, leaves, wood processing and utilization, at the same time, China also described the protection of natural forest birch, white birch industry development and The rational development and utilization of birch resources
