Abstract:

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.

Key words: forest quality assessment, analytic hierarchy process, index weight, Guangzhou City
