栓皮栎食叶害虫危害的林层分布及其环境驱动因素
Vertical distribution of leaf-eating pests of Quercus variabilis and its environmental driving factors in forest stands
摘要
Abstract
[Objective]Verical distribution characteristics and its environmental drivers of the leaf-eating pest damage in Quercus variabilis forest was investigated in order to provide theoretical reference for developing effective long-term ecological control strategy against forest pest.[Method]This study selected pure Q.variabilis forests and Q.variabilis-Platycladus orientalis mixed forests in the Qingli-ang Temple forest area of Dengfeng Forest Farm,Henan Province,as research subjects.Structural equation modeling(SEM)was employed to explore the effects of stand characteristics,understory veg-etation diversity,and surface features on the damage severity of leaf-eating pests across different forest layers.[Result]1)The damage severity of leaf-eating pests was significantly higher in mixed forests than in pure forests,with the lower canopy layer exhibiting significantly greater damage than the upper canopy and seedling layers.2)Pest damage in the upper canopy was primarily regulated by stand char-acteristics,while the influence of understory plant diversity and surface features gradually increased with the decreasing of the forest layer.3)Q.variabilis forests with higher biomass provided abundant food resources,favoring the feeding activities of leaf-eating pests.4)Rich herbaceous plant diversity significantly suppressed the damage caused by Q.variabilis leaf-eating pests.[Conclusion]In the pre-vention and control of Q.variabilis leaf-eating pests,enhancing herbaceous layer species diversity and improving the stability and natural defense capacity of Q.variabilis forests are critical strategies for achieving sustainable management of Q.variabilis plantations.关键词
