Research on Forest Quality Evaluation in Yantai City
Using 30 sample plots in Yantai City as the research object,the Analytic Hierarchy Process(AHP)was employed to comprehensively evaluate the forest quality,including setting forest quality as the target layer,using forest stability,forest productivity,and forest ecological efficiency as evaluation criteria,and constructing an indicator evaluation system based on 10 evaluation indicators(unit area tree density,forest health level,canopy density,tree species structure,average diameter at breast height(DBH),average tree height,soil layer thickness,unit area volume,biodiversity conservation value,and vegetation carbon density).The results indi-cated that forest productivity was the dominant factor in evaluating forest quality,and the average DBH,average tree height,and tree species structure were important evaluation factors bearing the highest comprehensive weight,accounting for 0.6181 of the total.Overall,the forest quality of the sample plots was concentrated in the"average"and"poor"levels,accounting for 36.67% and 26.66% of all,respectively.The comprehensive im-provement of forest quality can be achieved through precise improvement of forest quality,further optimization of stand structure,and adjustment of tree species composition.
