FORECASTING THE OCCURRENCE POPULATION OF SECOND GENERATION BOLLWORM IN DIFFERENT AREAS BY FUZZY COMPREHENSIVE EVALUATION CLASSIFICATION
Hua Yaonan Hua Chongzhao Forecasting Station of Crop Pests of Shandong Province
The method of Fuzzy comprehensive evaluation could be adopted when observed data are incomplete but having abundant practical experience. On the basis of practical experience, the single factor relative matrix is composed.While it is treated by weighting, the multifactor comprehensive relative matrix is obtained. Then by Fuzzy classification analysis, certain factors of second generation bollworm muster of a certain area and a certain factor of grade muster of its occurrence population are classified into the same kind. So forecastint could be made. It is a new improved Fuzzy analytical method for forecasting agricultural diseases and pests,which could be adopted when lack of complete data and having practical experience.
