松墨天牛林间监测序列的联合动态

Joint Dynamic of Monitoring Series for Monochamus alternatus in Forests

为查明不同诱捕点间松墨天牛林间种群的动态变化及其相互联系,用联合密度依赖方法对4个试验点2008—2010年的诱捕序列进行分析。结果表明:4个试验点间松墨天牛种群相互影响,用极大似然法对4个试验点的林间松墨天牛监测序列联合建立的模型具有较高的拟合精度。

Joint density dependence was used to analyze the monitoring series for Monochamus alternatus in four experimental locations, in order to explore M. alternatus population dynamics and their interconnections in forests with different trapping locations. Results show that the monitoring series in the four experimental locations are interconnected, and the model of monitoring series jointly established by the maximum likelihood method has a high fitting precision.
