| 摘要: |
| 以 2020 年广东省西江林场森林资源二类调查数据为依据，对林场森林资源及生态状况进行与
分析。结果表明：（1）林场森林覆盖率高，林地与林木资源丰富。（2）林场主要以生态公益林为主，其
余少部分为用材林和经济林，经济林品种较为单一。（3）除幼龄林外，各龄组面积分布均匀。（4）林场
乔木林中纯林面积占比大，林相简单，单一树种抗逆性较弱。（5）林场林地开发利用条件较好，森林健
康度良好，保护等级结构基本符合林种及林场的功能定位。（6）林地整体生态功能一般，森林景观等级
不高。根据分析进一步指出西江林场经营管理过程中存在问题，并提出经营管理对策与建议。 |

| Abstract: |
| This paper summarizes and analyzes the forest resources and ecological status of the forest farm,
based on the data of the forest resources class II survey in Xijiang Forest Farm in Guangdong Province in 2020.
Here are the results. (1) the forest coverage is high and the forest land and forest resources are abundant. (2) The
forest mainly consists of non-commercial forests, while the remaining part is timber forests and economic forests,
and the economic forests are relatively single species. (3) Except for young forests, the area of each age group is
evenly distributed. (4) The area of pure forests in the farm is large, the forest phase is simple, and the resistance
of single species is weak. (5) The development and utilization conditions of the forest land are good, the forest
health is good, and the protection grade structure is basically in line with the forest species and the functional
positioning of the forest land. (6) The overall ecological function of the forest land is at the average level, and the
forest landscape grade is not high. According to the analysis, the problems in the management process of Xijiang
Forestry are further pointed out, and management countermeasures and suggestions are proposed. |
