摘　　要：对草地植被净第一性生产力的Miami模型和Thornthwaite Memorial模型模拟值结果与实测值结果进行分析和比较。首先通过建立散点图计算相关系数,得到了实测值与模拟值之间存在线性关系,并使用R语言软件估算出两者间的一元线性回归方程。然后对参数进行显著性分析,但分析结果无法判断哪种模型更适合,最后通过进一步做拟合优度分析明显看出Thornthwaite Memorial模型模拟效果优于Miami模型,这一结论对今后中国在植被净第一性生产力方面更深入的研究提供了参考依据。This paper focuses mainly on the grassland vegetation net primary productivity of two kinds of statistical model—Miami model and Thornthwaite Memorial model,whose simulated values and observed results are analyzed respectively.Through the establishment of a scatter diagram,the correlation coefficients are calculated to get a linear relationship between simulated values and observed values.By using R language software,the unary linear regression equation between them is estimated to make the significance analysis of the parameters.But the results cannot determine which model is more suitable,thus the goodness of fit is analyzed,and it is obvious that the simulation effect of Thornthwaite Memorial model is better than that of Miami model.It will provide references for further studies in the aspect of vegetation net primary productivity in our country.
