摘要: 在详细探讨林带防护成熟概念的基础上,依据林带树木生长规律,建立了林带防护成熟龄与更新龄的确定方法,具体确定了北京杨、小钻杨等5个杨树品种林带的初始防护成熟龄、更新龄和更新期,并对林带不同更新方式进行了效益评价。

关键词: 林带, 防护成熟, 更新

Abstract: Based and on a detail approach to the PM of shelterbelt on the growth pattern of it, the methods for determining PM and regeneration ages(RA) are established. Initial protective maturity age (IPMA) and RA of 5 poplar species shelterbelts such as Populus beijingensis, P. xiaozhuanica ect. are determined as the examples. Meanwhile, benefit evaluation in different regeneration patterns is also made in this paper.

Key words: Shelterbelt, Protective maturity, Regeneration
