Comprehensive Evaluation on Agricultural Basic Drought Based on Wavelet Neural Network

According to evaluation system and rating standard of agricultural basic drought,a comprehensive evaluation method of drought based on wavelet neural network was proposed.Using MATLAB simulation software,the corresponding programs were written,and the model was applied in the drought comprehensive evaluation in Guanzhong area.The results showed that the assessment results were objective and accurate,convergence speed was fast,which provided a scientific basis for making the plan of drought relief and disaster alleviation drought and disaster.
