通过对光皮桦的分布、适生环境、天然及人工状态下的生长特性研究表明，光皮桦具有喜光、耐瘠薄、适应性强、生长期长等特点；光皮桦种子在常温下不耐贮藏，应随采随播；苗木生长较快，苗高为全期生长型，而苗木直径生长的高峰约滞后高生长高峰1个月；天然光皮桦具有2次以上的直径与树高生长高峰，材积持续速生，人工林速生更早，速生水平更高。可采用人工造林、萌芽更新或人工促进天然更新。研究结果为光皮桦的保护、合理利用及资源的发展提供指导。

Distribution, fit environment and growth property of B.huminifera Winkl from natural and plantation forests were studied. The result showed that B.luminifera is of light inclination, barren－resistance, strong adaptation and long growth period. The seeds of B.luminifera are difficult to store under normal temperature and they must be sown as soon as they are collected. Nursey stock of B.luminifera grows quickly and its height growth lasts an entire period while the peak of diameter growth for the nursey stock of B.luminifera is about one month later than that of height growth. Natural B.luminifera has more than twice growth peaks of diameter and height, its wood valume grows rapidly continually. The rapid growth period of B.luminifera from plantation forest is earlier with better capability. It’s renewing can be carried out by artificial plantation and germinatior on natural renewing enhanced artificially. The conclusion provides direction for protection, rational use and development of B.luminifera resource.
