基于有序流动的阳澄淀泖区流速水质相关性分析
|
摘要
阳澄淀泖区为平原河网区,在适度的引排调度下使河湖水流有序流动,对于合理蓄泄洪涝水、调控水资源、改善水生态环境意义重大。以阳澄淀泖区有序流动调水试验的水量、水质监测数据为基础,从最能直观反映水体有序流动的水量指标-流速出发,利用SPSS软件计算流速与水体重要水质指标之间的相关关系,研究河湖水体有序流动中流速与水质的响应机制。研究结果发现流速-溶解氧的相关性最强,引水口门及原本滞流较重的河道流速与各水质指标之间相关性更强,水质改善更显著;但通过工程调度只能一定程度上改变水环境,与水质产生直接的相关关系很难。研究成果可为评估水流有序流动对河网水环境改善的实际效果提供技术支撑,对研究区域确定合理的引排调度方案,改善水质有积极的意义。
Yangcheng-Dianmao area is a plain river network area. The orderly flow of rivers and lakes under proper diversion and drainage scheduling is of great significance for flood rational storage,water resources regulation and aquatic environment improvement. Based on the data of flow velocity and water quality measured during regulation experiment in Yangcheng-Dianmao area,this paper uses SPSS software to calculate the relationship between important water quality indicators and flow rate that most directly reflect the orderly flow of water,and further analyze the response mechanism of flow velocity and water quality of the rivers and the lakes under orderly flowing. It is found that the flow rate-dissolved oxygen has the strongest correlation; The flow velocities at water diversion entrances and in the frequently non-flowing rivers are more correlated with the water quality indicators,and the water quality improvement is more significant; The engineering regulation measures can only change water environment in some extent but is hard to generate a direct correlation with water quality. This research can provide technical support for evaluating the actual effect of orderly flowing in rivers and lakes on the environment improvement,and has a positive meaning to improve the water environment under the comprehensive flow regulation of the study area.
