Abstract:

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.

Key words: One-dimensional series, Correlogram, Spatial structure, Space-time correlation, Population dynamics
