水利水电技术（中英文）

本文着重探讨河流主要有机污染参数化学需氧量(COD)、氨氮(NH₃－N)和挥发酚随时间变化的特性和趋势，利用自相关、互相关分析的方法和平滑的方法对上述有机污染参数进行站间及同站相关性、发展趋势的研究，为进杆水质预报和河流管理提供了一个有效的统计分析方法．

This paper foctises on the correlntion and trend problems of river water quality main or-ganic parameters (COI)' AH3-N, voIapiIe phenols ). Mutual - correlation method, Self- correlation method and Smoothing mcthod have been devcloped - which provide approaches to dealing with the' in-terstation correlation and trend analysis for organ ic paranmeters. The major sttldies involved of two as-pects: (1) mutual correlation and self correlation analysis of mterstation; (2 ) trends analysis of water quality organic parameter time series.
