朱庄水库水质年内变化规律分析

摘要

In this paper,the comprehensive pollution index method is used to calculate the each month water comprehen-sive pollution index of Zhuzhuang reservoir, and calculate the perennial average value,and then draw the annual variation curve of quality comprehensive pollution index,using this to reflect the change of water quality. Through the analysis, the comprehensive pollution index is high in April, June and August within the year of Zhuzhuang reservoir, and it is low in February,October and December.Analysis of the changes of water quality during the year by comprehensive pollution index method,which can reflect the variation law of water quality in microscopic scales, is an effective method to evaluate the water quality changes within a narrow range.%采用综合污染指数法计算朱庄水库水体各月综合污染指数，并计算其多年平均值，然后绘制水质年内综合污染指数过程线，用综合污染指数反映水质变化。通过分析，朱庄水库年内4，6，8月综合污染指数偏高，而在2，10，12月综合污染指数较低。采用综合污染指数法分析水质年内变化，可从微观上反映出水质年内变化规律，是评价水质变化幅度不大时的一种有效方法。
