| 摘 要： | 针对目前的水文相关分析只能描述水文变量之间宏观上的相关关系这一不足,提出用集对分析的联系度刻画水文变量之间微观上的相关结构,分析了相关结构中各种关系成分所占的比例和性质.在此基础上,探讨了基于集对原理的因变量主要影响因子的识别方法,并用于径流回归分析中.实例分析表明,基于集对原理的水文相关分析比常规水文相关分析更为有效、客观和合理,在水文水资源学中具有重要的应用价值.

| Abstract: | The Set Pair Analysis(SPA) has been introduced into the relation analysis of hydrological variables.The connection degree of SPA can display the detail related structure of hydrological variables,the property and ratio of all relations from the related structure have been probed.Based on the above results,an approach of selecting main impact factors of depended hydrological variable has been suggested,which was applied to the analysis of runoff regressive function.The case studied results showed that the re... |
