| 摘 要： | 土地定级因素的权重是土地定级因素对土地评价结果影响大小的量度,其精度的高低在一定程度上决定着土地级别划分的精度。为减少层次分析法的主观程度,在层次分析法计算因素权重的基础上,研究了如何运用群体决策方法来确定其综合权重。首先,在单一专家的情况下,运用层次分析法依次求出基本因素权重,接着利用CR求出群体决策中3位专家所获得的相对权重,对每一因素的权重进行线性加权,得出基本因素的最终权重,最后,采用同样的方法求得层次结构中每一层各定级因素的最终权重。

| Abstract: | The factor weight of land gradation is a measurement which impacts on the land evaluation result and its precision decides the gradation precision to some extent.In order to reduce subjective influence of AHP,the synthetical weight was determined according to the method of group decision based on AHP(analytical hierarchy process).First of all,the basic factor weight was calculated by each expert applying analytical hierarchy process.Secondly each expert's relative weight was determined according to CR in gr... |
