| 摘 要： | 目的：地表水水质随季节性变化较大，为了更准确地评价某地区全年地表水环境质量，尝试将不确定多属性决策方法中的区间数排序法用于水质评价。方法：将地表水环境质量标准值与不同时期的水质监测数据分别定义为区间数，利用区间数比较的可能度公式，得出两者可能度关系并进行排序。排序结果显示，浑河东陵大桥处2006年水质劣于地表水V类标准值的可能度为0．531，即2006年浑河东陵大桥处水质为劣V类。结论：基于区间数排序的地表水环境质量评价方法考虑了全年不同时期的水质变化情况，与模糊综合评判法得出的结果基本一致，可比较准确地评价某地区全年水质状况。

| Abstract: | Purpose:Surface water quality can change a lot by season. In order to assess exactly surface water quality of a section nearly,this papat tyries to use an environmental quality assessment method for surface water based on the ranking interval number. Method: The environmental quality standard for surface water and the monitored data are defined as the interval numbers,and then get the relationship of possibility degree between them,according to the possibility degree formula for comparing the interval numbe... |
