秩相关分析在地下水位变化趋势评价中的应用——以安徽省淮北平原孔隙水为例

The application of rank correlation analysis on the evaluation of trends in the pore groundwater level changes in Huaibei Plain,Anhui Province

摘要: 应用Spearman和Kendall两种秩相关分析方法,以SPSS为平台,对安徽省淮北平原区域及两个典型城市的不同流动系统孔隙水水位变化趋势进行评价,并与水位动态曲线直观判读结果对比。结果表明:两种秩相关分析方法评价结果基本一致,与水位动态曲线法相比较,评价尺度统一,理论严密,操作简便,效果良好。

Abstract: Two kinds of rank correlation analysis(Kendall and Spearman) were used with the SPSS software in this paper,the trends in pore groundwater level changes of different flow system in Huaibei Plain of Anhui Province and the two typical urban areas were evaluated.And contrasting with the intuitionistic determining results of the curve of groundwater level.The trend evaluate results of the two methods of rank correlation analysis were basically in the same.For this two methods had rigorous theory and...
