| Abstract: |
| Ecological public welfare forest quality evaluation can objectively reflect the quality of forest
resources and provide a basis for accurate improvement of forest quality and sustainable management. Applying
the analytic hierarchy process and fuzzy comprehensive evaluation method to evaluate the forest quality of the
ecological public welfare forest in Jiaoling county, Guangdong，the system of the ecological public welfare forest
quality evaluation index system and the classification standard are constructed, and the comprehensive quality
score is calculated. The results showed that the two categories of 10 evaluation indicators (mean diameter at breast
high, average height, crown density, hectare accumulation of standing trees, age group, dominant tree species, tree
species structure, forest community structure，vegetation coverage, disaster level) were more comprehensively
reflect the forest quality status in the area. Among them, vegetation coverage has a greater impact on forest quality,
followed by crown density and tree species structure, and dominant tree species have less impact. In general, the
quality level of ecological public welfare forest resources in Jiaoling county is medium, which is mainly reflected in the high vegetation coverage, good crown density, and the accumulation of standing trees in hectares, average
diameter at breast height, and average tree height are all at a medium level, and the disaster situation is light.
The forest community structure is relatively complete. The dominant tree species are mainly local dominant tree
species. The tree species structure is mostly relatively pure and pure forests, and there are few mixed forests. The
forest stands are mostly middle-aged forests and over-mature forests. The management of the ecological public
welfare forest in Jiaoling county should strengthen forest tending and pay attention to the adjustment of forest
stand structure. |
