摘要
通过多年对查干湖水质的监测以及近几年逐月监测参数,综合分析水体溶解氧变化趋势和驱动机制,总结出导致溶解氧浓度降低的原因,除了光合作用影响外,溶解氧浓度较低的补给潜水、水体中存在的还原性物质也是主要因素。提出将潜水变为地表水、增加对水体中还原性物质的转化能力等增加溶解氧的措施。
This papar comprehensively analyses the trend of dissolved oxygen and its mechanism in Chagan Lake water body,through water quality monitoring of many years and monthly monitoring parameters in recent years.It summed up the causes of leading dissolved oxygen concentration reduced,which were the photosynthesis,the potential recharging water to groundwater and the reducing substances existing in the water.It put forwards the measure of changing the potential water into surface water which can increase the reducing substances conversion to increase dissolved oxygen.
