| Abstract: | Three types of spatial pattern formation processes,distribution transformation,generalized distribution and compounded distribution,are studied.The result of 11 kinds of generalized distribution and 9 kinds of compounded distribution is listed.Three types of spatial pattern determination methods,index of dispersion method,spatial autocorrelation method,and parameter changing method,are proposed,these methods are also used to determine how the spatial distribution was formed.The spatial pattern formation of pine caterpillar is used as a simulation example,the result indicates that the spatial distribution of pine caterpillar is compounded negative binomial distribution the individual group distributed randomly,individuals aggregate in individual group,and the distribution of individuals in group is Gramma distribution. |
| Keywords: | spatial pattern formation generalized distribution compounded distribution spatial pattern determination. |
