广东省短轮伐期造纸林基地建设的探讨

ON THE DEVELOPMENT OF PULPWOOD FORESTRY WITH SHORT ROTATION IN GUANGDONG

根据我国造纸工业发展的历史教训,借鉴国外成功的经验,我省应走林纸联合道路並在中南部地区大力发展短轮伐期造纸原料林基地,尽快地向使用小径级幼材的方向转变。本文讨论了在我省中南部地区建设短轮伐期纸浆林基地的必要性;提出以马占相思和桉树作为本区营造短轮伐期纸浆林的主要树种;同时详细地阐述了基地建设和制浆造纸的技术关键,即优树无性系扦插育苗,幼林密植、短期轮伐,提高坡地自然生产力以及全树制浆技术和漂白;最后,提出按不同立地类型宜建设三大类型的短轮伐期纸浆林基地。

Refering to the successful and unsuccessful experiences in developing paper industry in China and in other countries, the authors consider that in Guangdong Province the road of co-operation between forestry and paper industry should be taken and the structure of paper-making materials should be changed. Small wood instead would be used as material of paper-making before long. The pulpwood forestry bases with short rotation should be built up on a big scale on the hillside and sloping land in the central southern part of Guangdong Province. That is a correct way for paper industry that suits the conditions of Guangdong. Some tree species for pulpwood are recommended, and three types of pulpwood forestry base in terms of site classfication are presented in this paper.
