| 中文摘要: |
| 利用广西森林资源连续清查成果数据,从数量、结构、质量3个方面研究了广西天然林资源的
动态变化态势。研究结果表明,在1985—2020年间,广西天然林资源总量大幅增长,天然林总面积
增加206.09 万hm2,天然林总蓄积量增加2.77 亿m3;天然林面积正从高位回落,且仍未止跌企稳,
但下降速度已明显减缓;天然林蓄积量仍有较大的增长空间;天然林中乔林、灌木面积比大幅减小,
天然林总体质量仍处于较低水平。 |
| 英文摘要: |
| Using the data from the continuous inventory of forest resources in Guangxi, this study examines
the dynamic changes of natural forest resources in Guangxi from three aspects: quantity, structure,
and quality. The results indicate that between 1985 and 2020, the total volume of natural forest resources
in Guangxi increased significantly, with the total area expanding by 2.060 9 million hectares and the total
growing stock increasing by 277 million cubic meters. However, the area of natural forests has been declining
from a peak level and has not yet stabilized, though the rate of decline has slowed noticeably.
There remains considerable potential for growth in the stock volume of natural forests. The proportion of
arbor forests and shrublands within natural forests has decreased substantially, and the overall quality of
natural forests remains relatively low. |
