摘  要:
定级因素权重的确定是土地定级中一项重要的内容,传统方法通常都是根据决策者的先验知识主观确定,基于粗集理论的单个属性权重确定方法无法解决简化因素的权重问题。结合土地定级实际,提出了基于粗集理论的组合权重确定单个因素权重的方法,并利用主观和客观结果综合确定权重。

摘  要:
The determination of grading element weight is an important content of land grading.In the traditional method,it was determined according to the experience knowledge of decision makers.The determination method of single attribute weight based on rough set theory could not resolve the weight of simplified element.Combining with the practice of land grading,a method of confirming the single element weight based on rough sets' integrated weight was put forward.And the weight was synthetically confirmed by using subjective and objective results.
