摘要
构建了耕地质量等级评价指标体系，分别采用层次分析法和因子分析法计算指标的权重，并进一步研究了组合赋权法的计算方式，并以土默特右旗耕地质量等级评价为实例对该方法的实际应用进行研究。结果表明，层次分析法确定权重的主观因素较强，而因子分析法计算权重过程又相对机械化，采用将二者计算的权重进行线性组合的方式来确定耕地质量等级评价指标体系较为科学，在实际工作中值得参考。
Abstract
The evaluation index system of cultivated land quality grade was constructed, the weight was calculated by using AHP method and factor analysis method, the calculation way of combination weighting method was further studied.With Tumd Right Banner as example, the practical application of the method was analyzed.The results showed that using AHP method to determine weight had strong subjective factors, while using factor analysis method was relatively mechanized.Conducting linear combination to determine the evaluation index system is more scientific and is worth reference in practical work.
