基于多元图形特征与云模型理论的质量评价方法研究*

针对综合质量评价中评价结果不能充分反映主、客观因素共同作用的问题，提出了一种基于多元图表示原理与云模型理论相结合的综合质量评价方法。该方法基于多元图表示原理，应用雷达图表示方法的图形面积融合多指标参数，结合云模型理论定性定量转换强大功能，实现综合质量评价，得到符合人类思维方式的定性定量综合评价结果。以成都市土壤为研究对象，实验结果表明，该方法得到的定性定量相结合的综合评价结果符合实际数据的分布和人的思维方式，是一种充分反映主、客观因素共同作用的评价方法。该方法适用于多指标参数的质量评价问题。

Research of soil evaluation based on cloud model and multi-parameter chart presentation

In order to obtain the result of quality assessment with both quantitative and qualitative presentation, this paper researched a new assessable method based on the chart expression theory and the cloud mode theory. Used the radar chart theory to fuse the multi-parameter, so the basic assessment result was got ton and it was visual. Researched the quantitative and qua-litative information transform based on the trait of cloudy model. The experiment was finished with the soil data in Chengdu. The result is being reacted the sense of human being with quantitative and qualitative information. It is an effective method.
