用微分动态模型预测内蒙古天然草场产草量

Estimation of Rangeland Yield in Inner Mongolia by Calculus Dynamic Model.

利用内蒙古自治区草原工作站的连续7 年(1991 ～1997) 天然草场第1 性生产力的技术资料经统计分析, 使用微分动态建模对内蒙古自治区30 个牧业旗县的天然草牧场牧草产量, 以旗县为单位做了预测, 并通过了后验残差检验, 合格率为90 % 。

Based on data from the field recording of rangeland yield in 30 counties in Inner Mongolia from 1991 to 1997,a calculus dynamic model is proposed for routine use,and which is tested by calculus of residual error.90% of the result are up to standard.
