摘要
1977~2010年,广西森林资源发生了巨大变化,林地面积由1 396.32万hm2增加到1 527.17万hm2,增长9.37%;有林地面积由531.36万hm2增加到1 116.38万hm2,增长110.10%;活立木蓄积由2.56亿m3增加到5.58亿m3,增长117.97%。根据广西历次森林资源连续清查结果,阐明不同时期广西森林资源变化动态,并对政策和效益2个方面的驱动因素进行分析研究,提出新时期森林经营对策和建议。
There was dramatic change of forest resources in Guangxi from 1977 to 2010. The woodland area increased from 13. 9 632 million hm2to 15. 2 717 million hm2,with 9.37% increasing. The forest land area increased from 5. 3 136 million hm2to 11. 1 638 million hm2,with 110.10% increasing. The growing stock volume increased from 256 million m3to 558 million m3,with 117.97% increasing. Based on the results of continuous forest inventory,the dynamic change of the forest resources and the main driving factors on the policies and benefits were clarified and analyzed,and the countermeasures and suggestions for the forest management in the future were proposed.
