摘要

Abstract

Based on grain yield data of 23 main grain-producing provinces or regions and weather data of 105 meteorological stations in China from 1961 to 1995 , 23 meteorological good/bad grain harvest models have been set up .The accuracy of good grain harvest models is 89%(388/436 year-times),that of bad grain harvest models is 84.7%(111/131 year-times), and the total accuracy is 88%(499/567 year-times). Compared with actual total grain yields of 23 provinces/regions, the average accuracy of simulated total grain yields derived from the models is 97.63%, the minimal and maximal relative errors are 0.23% and 6.4%, respectively.
