摘　　要：在原有分析的基础上,用模糊综合评价与加权平均相结合的方法,对2002年渭河宝鸡段各监测断面的水质进行评价研究。结果表明各控制断面,除常兴桥水质处于国家地面水环境质量标准(GBZB1 1999)Ⅲ级与Ⅳ级之间外,其它各监测断面水质均超过Ⅳ级标准,其中虢镇桥、卧龙寺及蔡家坡断面水质接近Ⅴ级标准。被评价的6个段面水质优劣依次为林家村(对照段面)最好,常兴桥段面次之,胜利桥、卧龙寺、虢镇桥和蔡家坡段面较差。在参与评价的污染因子中,各段面均以氨氮污染最严重,石油类次之。此外林家村段面的亚硝酸盐氮,卧龙寺、蔡家坡和常兴桥段面的化学需氧量,常兴桥段面的生化需氧量也有一定程度的污染。To understand the pollution situation of Weihe River in Baoji, adopted the water quality with method of fuzzy comprehensive judgment and weighted average method, water quality about each monitoring section of Weihe River in Baoji are analyzed. The results indicated that the water quality of Changxing Bridge monitoring section was between grade Ⅲ and grade Ⅳ water quality formulated in national surface-water quality standard(GBZB1-1999). The water quality of other monitoring sections were worse than water quality of grade Ⅳ formulated in national surface-water quality standard (GBZB1-1999).Even the water quality of Guozhen Bridge monitoring section, Wolongsi monitoring section and Caijiapo monitoring section was close to grade Ⅴ water quality formulated in national surface-water quality standard (GBZB1-1999).The water quality of six judged monitoring sections is(from bad to worse)water quality of Linjiacun monitoring section (check section) was the best of all, Changxing Bridge monitoring section is second, the other monitoring sections were bad. And so on, the result of judgment indicated that the water of each monitoring section was first polluted by ammonia nitrogen (NH^+_4-N),then by mineral oil; the water of Linjiacun monitoring section was polluted most seriously by nitrite nitrogen(NO^-_2-N);The water of Wolongsi, Caijiapo and Changxing Bridge monitoring sections was polluted most seriously by chemical oxygen consumption(COD);and the water of Changxing Bridge monitoring section was also polluted seriously by biochemical oxygen demand(BOD).
