摘要
发展速生桉在一定程度上有效缓解了广西区乃至我国木材紧缺的局面。以南宁市林地布局及空间分析为基础,综合考虑扣除公益林后的林地面积以及速生桉生长的立地条件,确定全市发展速生桉的最大理论面积为38.46万hm2。根据南宁市五大类培育树种的规划比例以及林地保护利用规划成果,提出速生桉建议发展最大面积为31.92万hm2。并提出合理调整林种、树种结构,增强森林的综合功能及效益等建议。
The development of the fast growing eucalyptus might effectively relieve the pressure of wood shortage in Guangxi Zhuang Autonomous Region and even our country to some extent. Based on woodland layout, Woodland spatial analysis and comprehensive consideration of forestland area deducted public welfare forest area and site conditions for the growth of fast-growing eucalyptus, theoretical maximum area of the fast-growing eucalyptus area in Nanning are determined as 384,600 hm^2. According to the planning proportion of five cultivation categories of tree species and planning results of woodland protection and usage, max area of fast-growing eucalyptus are proposed to be 319,200 hm^2. Recommendations to make reasonable adjustments for forest species and tree structure enhance the overall functionality and benefits of forests and others also have been carried out in this paper.
