摘要:

林木引种驯化已经成为现代林业的重要组成部分。从现代林木引种驯化概念出发,对林木引种驯化策略进行了探讨分析, 对于中国林业的持续发展, 在理论和实践上都是十分必要的。建立遗传基础较宽的基本群体, 发展驯化种群和进行遗传改良是林木引种驯化策略中最重要的三个环节。林木引种也是增加森林生态系统生物多样性和对树木基因资源进行易地保存的重要手段。

关键词: 林木引种, 引种驯化策略

Abstract:

Exotic forestry has become a very important subject in the field of modern forestry and played a more important role than ever before in the development of plantation forestry, wood production, improvement of the living environment for human beings and gene conservation of forest resources. Even though having rich genetic resources of indigenous species, China still use a great number exotic tree species in plantation forests, which is estimated to be of a total area of 8 million ha for more than a quarter of the area of whole plantation forests in the country.A strategy for a long term tree introduction and domestication wherewith exotic forestry is developed. The strategy is essentially composed of the establishment of base population, development of land race and improvement of the land races with wide enough genetic base. Indigenous species which never be grown under silvicultural conditions should be included in the strategy to get naturalized. In the experimental design for field trials of the exotic species or provenance, a certain consideration should be given to the seed production and gene conservation for tree breeding in the future.
