摘要
宿鸭湖湿地麻皮蝽种群数量与黑杨群落分析表明,麻皮蝽发生与宿鸭湖湿地阔叶树、灌木层和草本层的比例、相对优势度成正相关(R=0.9775),其关系可以利用回归方程:Y=-51.35+27.19X(5)+0.41X(6)+1.62X(7)进行定量描述。增加黑杨的生态优势度和麻皮蝽的种间相遇机率可以明显增加Shannon-Wiener多样性指数,增加湿地灌木层的相对优势度可以明显增加麻皮蝽的发生率。
The population quantity of Erthesina fullo Thunberg and the community analysis of Populus nigra in SUYA Lake showed :the Erthesina fullo Thunberg occurrence was positive correlation with the broad-leaved tree, shrub layer and herb layer ratio and the relative dominance (R=0.9775), Their relationship could make use of regression equation to describe: Y= -51.35+27.19X(5)+0.41X(6)+1.62X(7).Moreover ,increased the ecological dominance of Populus nigra and PIE could obviously increase Shannon-Wiener diversity Index, decreased wetland shrub layer relative dominance could obviously reduce the incidence of Erthesina fullo Thunberg.
