| 摘 要： | 应用平均拥挤度指标、扩散指数等6种聚集度指标以及Iwao回归法、Taylor幂函数法等方法分析了白星花金龟种群在玉米田空间分布特征。结果表明:白星花金龟种群呈现聚集分布特征,并且聚集程度较高;分析拟合了白星花金龟在玉米田中的理论抽样数学模型。

| Abstract: | The spatial distribution pattern of the adults of Liocola brevitarsis (Lewis) in cornfields was analyzed by Iwao’s regression analysis and Taylor power principle. The results showed that the spatial distribution pattern of L. brevitarsis was highly aggregative. The models of theoretical sampling for L. brevitarsis adults were set up. |
