| Abstract: | 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. |
