| Abstract: | Based on the theory and methods of neural network,climatic data,geographical data and the occurrence quantity in north of Fujian province,an occurrence quantity forecast of Monochamus alternatus Hope was established.The results showed that the established neural network model had both satisfying fitting and forecasting precision.The mean forecast precision for occurrence quantity was 97.2% in two survey plots,and forecast accuracy was 100%. |
| Keywords: | Monochamus alternatus neural network occurrence quantity forecast |
