用一维序列方法研究昆虫种群时空结构

CHARACTERIZING POPULATION SPACE-TIME STRUCTURE USING ONE-DIMENSIONAL SERIES METHOD

提出了研究种群空间结构的一维序列方法，包括一维序列抽样、单种群空间结构分析、时空相关分析以及时空分析与种群动态预测之间关系。对马尾松毛虫空间结构分析表明，本文的方法能解决分布型指数方法无法解释的问题；对马尾松毛虫幼虫的时空分析表明一维序列分析用于研究种群扩散规律是合适的。

The one-dimensional series(1-D series) method was proposed to analyse the population spationtemporal structure. It included one-dimensional series sampling method,single population spatial structure analysis,space-time correlation analysis,and the relationship between space-time analysis and population dynamics forecasting. The result of pine caterpillar(Dendrolimus punctatus W. )sturcture analysis indicated that 1-D series method is much better than classical spatial pattern index methods, the space-time analysis result indicated that 1-D series method is also suitable for analysing population dynamics-spatial diffusion.
