| 中文摘要: |
| 以2004—2019年广西国有博白林场4期森林资源二类调查数据为基础,运用动态分析法结
合ArcGIS 软件,从林地类型、活立木蓄积量、森林质量等方面进行森林资源动态变化对比分析。结果表明,2004—2019年间,林地面积持续增加,活立木蓄积量和单位面积蓄积量呈先增后降的变化趋势,至2019年林场森林覆盖率达90.56%,森林资源实现量质双增;2019年中龄林、近熟林、成过熟林
占比为24∶21∶25,乔木林龄组结构趋于合理;杉类、松类树种种植面积增加,但桉树化趋势仍较突
出,树种结构失衡、林分健康问题凸显、林地利用率有待提高,急需调整相应森林经营措施,精准提升森林质量。针对林场出现的问题,提出可持续经营策略,以助推林场实现可持续经营与发展。 |
| 英文摘要: |
| Based on the second-class forest resource inventory data from 2004 to 2019 in Guangxi State-
Owned Bobai Forest Farm, dynamic analysis combined with ArcGIS software was used to compare and analyze
the dynamic changes in forest resources from aspects such as forest land types, standing stock volume,
and forest quality. The results showed that from 2004 to 2019, the forest land area continued to increase,
while the standing stock volume and stock volume per unit area exhibited an initial increase followed by a decline. By 2019, the forest coverage rate reached 90. 56%, achieving both quantitative and qualitative
growth in forest resources. The proportion of middle-aged, near-mature, and mature and over-mature forests
in 2019 was 24∶21∶25, indicating a more reasonable age-group structure in arbor forests. The planting
area of fir and pine species increased, but the trend of eucalyptus dominance remained prominent. Issues
such as imbalanced tree species structure, forest health problems were evident, and the utilization rate
of forest land needs to be improved, There is an urgent need to adjust corresponding forest management
measures and precisely enhance the quality of forests. In response to these challenges, sustainable management
strategies were proposed to promote the sustainable management and development of the forest farm. |
