为寻求最适合分析犁耕效果评价指标权重数值的方法，在田间试验取得犁耕效果评价指标测量值的基础上，采用层次分析法的 Excel表公式计算法、MatLab 特征向量法、yaAHP 软件求解法等3种方法求得到各犁耕效果评价指标权重数值及一致性比率。结果分析表明：3种方法求得犁耕效果各项指标的重要程度排序均为耕深稳定性＞土垡破碎率＞植被覆盖率＞入土行程＞耕宽稳定性；但权重值存在微小差别，一致比率分别为0．0463、0．0226、0．0225；yaAHP软件求解法得出的权重值更为精确可靠。分析可知：此3种算法均能求得犁耕效果评价指标的权重排序及权重值，可为农业机械适用性评价指标由定性评价转为定量评价提供参考。

To seek the most suitable for analysis of plough effect evaluation index weight value, the method of experiment with the plough in the field effect evaluation index on the basis of the measured value, using the analytic hierarchy process ( ahp) Excel table formula method, Matlab eigenvector method, software yaAHP solving method three kinds of methods, such as to get the plough effect evaluation index weight value and consistency ratio, Results the plough effect analysis of three methods was the sort to the importance of the evaluation index are The Plow depth stability >The broken rate >The vegetation coverage rate average >The grave stroke averages >The wideth stability;But tiny differences in weight value,Consistent ratio of 0.0463, 0.0226, 0.0225, respectively,YaAHP software method of weight value is more accurate and reliable.Analysis shows that the three kinds of algorithms can get plough effect evaluation index weight sorting and weight value of applicability evaluation index for the agricultural machinery from the qualitative evaluation to quantitative evaluation to provide the reference.
