基于作物产量历史丰歉气象影响指数的河北省葡萄产量预报对比分析
Comparative analysis of grape yield forecasting in Hebei province based on historical meteorological impact index of crop yield abundance
摘要
Abstract
This study utilizes grape yield data and corresponding meteorological data from Hebei province from 1981 to 2020.Based on the historical meteorological impact index of crop yield abundance,two methods-maximum probability method and weighted average method-were applied to develop grape yield forecasting models for dy-namic yield prediction analysis.Model validation results show that the accuracy rates of yield abundance trend pre-diction were 77.8%and 84.4%for the maximum probability method and the weighted average method,respec-tively,while the quantitative forecasting accuracy rates were83.1%and90.3%,respectively.Model evaluation re-sults indicated that during 15 yield abundance trend forecasts over 5 years,the maximum probability method had 5 errors,while the weighted average method had 3 errors,with quantitative forecasting accuracy rates of 89.9%and 94.0%,respectively.The weighted average method based on the historical meteorological impact index of crop yield abundance performed better in forecasting grape yield in Hebei province.关键词
