摘要
本文应用灰色理论对中国黄牛年末存栏数的变化和增长作了分析和描述，在计算机计算的基础上，产生灰色动态模型。并以1949～1994年中国黄牛年末存栏数为原始母数列，划分为八个代表性时段作为预测基础进行灰色预测。模型经检验，精度较高，符合要求。应用所建模型对中国黄牛未来二十年发展趋势作了预测。
A gray forecast on developing trend for Chinese yellow cattle quantity was studied based on 8 time stages from the total number of yellow cattle in 1949 to the number of cattle in 1994 of P. R. China. The gray dynamic forecast model was founded with the model the developing trend for Chinese yellow cattle quantity next 20 years was calculated.
