摘　　要：通过建立的渭河关中段水质水量响应关系程序,对渭河关中段不同代表年丰、平、枯水期水质水量响应关系进行了定量化分析研究。结果表明:现状年丰、平、枯水期化学需氧量(COD)和氨氮(NH3-N)浓度在林家村断面至常兴桥断面相对较小,低于地表水环境质量标准Ⅴ类水标准。从兴平断面污染物浓度开始升高,兴平断面至咸阳断面污染物浓度增幅较大,至沙王渡断面污染物浓度开始降低。不同代表年COD和NH3-N浓度变化规律大体相似,无论丰、平、枯水期,同一断面污染物浓度从小到大排序为:P=25%、P=50%、P=75%、P=95%,污染物浓度在丰水期时相对较小,其实是在平水期,枯水期污染物浓度较丰水期和平水期时增幅较大。The program of the relationship between water quantity and quality was developed and the quantitative analysis for water quality and quantity response relations in the wet,flat and dry season in different representatives years in the Guanzhong Reach of Weihe River were made.The results showed that the concentrations of COD and NH3-N were relatively low between the Linjiacun section and Changxingqiao section and met the Class Ⅴ surface water quality standard.The concentrations of pollutants increased from the Xingping section and increased considerably between the Xingping section and Xianyang section,and then began to decrease from Shawangdu section.The concentration variations of COD and NH3-N were similar in the different representative years.The same section of pollutant concentrations in the wet,flat and dry season from small to large were as follows： P=25%,P=50%,P=75%,P=95%.The concentration of pollutants in the wet period was relatively small and in dry period was considerably large.
