以广州流溪河林场10块样地为研究对象,采用层次分析方法,以林分稳定性、林分空间结构和林分生产力为准则选取10个评价指标,综合评价森林质量。结果表明:流溪河林场森林质量整体水平处于良的水平,森林质量优等级占30%、良等级占40%、中等等级占30%;森林质量评价准则层权重由大到小依次为林分生产力(0.593 6)、林分稳定性(0.249 3)、林分空间结构(0.157 1)。通过低质低效林改造和中幼林抚育,科学合理调整林分结构,加强森林灾害预警监测,可提高流溪河林场森林质量。

The research took 10 sample plots in Liuxihe Forest Farm in Guangzhou as the object.10 evaluation indexes were selected with the criteria of stand stability,stand spatial structure and stand productivity by using the analytic hierarchy process to comprehensively evaluate the forest quality.The results showed that the overall level of forest quality in Liuxihe Forest Farm was at a good level,with excellent forest quality accounting for 30%,good forest quality accounting for 40%,and medium forest quality accounting for 30%;The weight order of forest quality evaluation criteria layer from large to small was stand productivity (0.593 6),stand stability (0.249 3),and stand spatial structure (0.157 1).The forest quality of Liuxihe Forest Farm can be improved through the transformation of low-quality and inefficient forests and the tending of young and middle-aged forests,the scientific and rational adjustment of forest structure,and the strengthening of early warning and monitoring of forest disasters.
