摘要

根据东辽河流域的自然特征

以二龙山水库为界

将东辽河分成山区和平原区河流两段进行研究。采用主成分分析的方法

探讨了不同统计口径水质演化的年际和月变化特征。采用相关分析法

分析了水质演化与环境酸化之间的关系。东辽河流域水质污染较为严重

必需进行及时有效的综合整治;流域水质演化的动力学因子主要为有机污染类物质

平原片和全流域统计口径污染因素类似程度较高

从整个流域来看

二龙山水库以下的污染 (包括公主岭市的城市污水和梨树县的农业污染)是一个不可忽视的因素;水质演化具有明显的逐月和年际变化规律;水质演化对环境酸化具有很好的响应。

Abstract

Based on physical features of the basin，the Dongliao river is divided into two parts，namely hill- river and plainiiver with the Erlongshan lake as the bound- The monthly and yearly evolution of water quality were studied by means of PCA，and its response to environment acidification is analyzed by means of correlation. The water is seriously polluted and must be renovated. The primary pollution factor is organic mat?ter. The pollution of lower reach must not be neglected. The evolution of water quality is monthly and yearly， and the response to the acidification of environment is strong.
