摘要
分析了作物模拟研究中模型检验的常用统计判据相关系数、标准差与变异系数在统计学意义上的原理和不足 ,提出了模拟值的置信度和置信带的概念。以玉米发育期模型为例 。
The paper expatiated the statistical principia and their deficiencies of correlation coefficient, standard deviation and variation coefficient most in common use in model verification, and for the first time brought forward the co nceptions confidence degree and confidence zone of simulated values. Conducted t ests orderly with the confidence degree and correlation coefficient betwee n values simulated and actual values for maize growth and development.
