| Abstract: |
| The relationship between the forming of fishing ground and the oceanic spatio-temporal field is nonlinear. In order to analyse the relationship between variables with spatio-temporal structures,a spatio-temporal pattern extracting model is provided to find the reason for the forming of fishing ground. In the model, the spatio-temporal structure of the oceanic factors is expressed as neighbour.The elements in the neighbour are filled in the table of decision-making system. After a recursion processing the spatio-temporal rule will be extracted with the spatio-temporal structure. And a experiment is given to show how to find the temperature pattern for the forming of the fishing grounds in Dasha area.It shows that the model is active and it should be the research front for the marine fishery. |
