摘要
选取总固体、总硬度、硝酸盐、氯化物、氟化物、六价铬等六种主要污染物,利用集对分析的方法,将超标率、污染指数和超标面积指数综合起来,对1985-2003年西安建成区地下水进行了动态评价。该方法既克服了依靠某年监测值对地下水质的静态空间评价,又可将超标率、污染指数和超标面积综合起来,完成地下水水质的动态评价。
The article chooses six kinds of main contamination such total solid, total hardness, nitrate, chloride, fluoride and six-valence Chromium etc. Using the method of set pair analysis, it collects standard excess rate, pollution index and area index of standard excess, dynamic evaluates groundwater in urban area of Xi＇an city from 1985 to 2003. The method not only can overcome static -space evaluation of groundwater quality depending on monitoring value in certain year, but also sum up standard excess rate, pollution index and area exceeding standard to achieve dynamic evaluation of groundwater quality.
