摘　　要：[Objective] Water quality variation trend of Wei River was analyzed and the water quality evaluation was performed in this study. [Method] Stationing and water sampling were conducted along Wei River at three different sites during the 12 months from January to December of 2014, the water samples were pre-treated and analyzed on chemical pollution indexes with the national standard, water quality data of Wei River in the 12 months was processed with periodic time series method, Spearman rank correlation coefficient was adopted to test pollution changing trend, and water quality status of Wei water was evaluated with integrated index of organic pollution. [Result] NH3-N and TN of Wei River exceeded the standard＇s lim- its; [ Y~ [ 〉Wp=0.506, [ Yss~ [ 〉Wp=0.506 and [ Y＆=0~,, Diecqieo 〉Wp=0.506 indicated that the integrated index of organic pollution of Shawangdu section, S.huyuan section and Tongguan Diaoqiao section showed a significant downtrend, respetively; and the water quality of the three sections became better, and it was worth noting that it was necessary to strengthen the water quality control of Wei River from January to June, so as to ensure that the water quality of Wei River reached the standard all the time. [Cendasien] This research was of significance in improving water ecological environment in Weinan as well as rationally utilizing water resources and finally realizing permanent development. Key words Wei River; Water quality variation trend; Integrated index of organic pollution; Evaluation[目的]分析渭河水质变化趋势并进行质量评价。[方法]于2014年的1月-12月份期间在渭河沿程对3个不同的地点上的渭河水进行布点并采集水样。预处理和分析水样当中的化学污染指标使用国标法．然后对12个月渭河水质运用周期性时间序列法整理数据并用Spearman秩相关系数检验污染变化趋势定量对变化作出分析。用有机污染综合指数法来评价渭河水质状况。[结果]渭河水质NH，N、TN超标，｜Ys沙王〉Wp=0．506，表明沙王渡断面有机污染综合指数呈显著下降趋势：｜Ys树园｜〉wp=0．506，表明树园断面有机污染综合指数呈显著下降趋势；｜Ys淮关吊桥〉wp=0．506，表明潼关吊桥断面有机污染综合指数呈显著下降趋势；这3个断面的渭河水质有所变好，值得引起注意的是，继续巩固加强对1--6月的渭河水质控制管理，以确保渭河断面水质能够一直达标。[结论]该研究对于改善渭南人民生活生态环境的现状。以及水资源的合理利用及长久发展具有重要意义。
