| 摘 要： | 立足于环境容量的分区分时控制,依据2000-2004年水质监测资料,对渭河关中段4种主要污染因子的时空变化及其与河川径流量的关系进行了分析。结果发现：①高锰酸盐指数、氨氮离子、BOD浓度沿河流断面呈上升趋势,而DO呈下降趋势,其中,天江人渡、沙王渡和树园3个断面高锰酸盐指数、氨氮离子、BOD浓度最高,属于严重污染断面;...

| Abstract: | In order to control environmental capacity divisionally in time-sharing way,in this paper the water quality monitoring data measured during the period from 2000 to 2004 were used to analyze the spatiotemporal variation of the 4 main pollution factors and their relationships with runoff volume of mainstream section of the Weihe River in Shaanxi Province.The result are as follows:(1) Permanganate index,ammonium ion and the BOD concentration were in an increase trend at all the cross sections,but the DO was in... |
