摘　　要：溶解氧是水体污染状态评价的重要指标,通过分析某河流水体中溶解氧含量与温度的关系,可以得出,溶解氧含量呈现秋冬高,夏季低的季节性变化特征。溶解氧与温度呈显著负相关。此现象与水体中浮游生物的光合作用以及溶解氧随温度的变化相关。评价水体溶解氧变化需要根据不同水体的特性综合考虑。Dissolved oxygen is an important index for the evaluation of water pollution.By analyzing the relationship between dissolved oxygen content and water temperature in a river,it can be concluded that the dissolved oxygen content is high in autumn and winter,but is low in summer.There was a significant season correlation between dissolved oxygen and water temperature.This phenomenon is related to the photosynthesis of plankton and the change of dissolved oxygen with temperature.To evaluate the change of dissolved oxygen in water,it is necessary to comprehensively consider the characteristics of different water bodies.

关 键 词：溶解氧 水温 季节性变化规律
