【摘要】 我国北方地区水资源供需矛盾突出,建立区域水资源预警机制尤为重要。以非汛期为例,提出了基于水量和基于水质水量耦合的警戒线与预警区的划定方法及对应的水资源预警方法。考虑到预警期长短,提出了点预警和过程预警;考虑预警期间降水对预警级别的影响,提出了动态预警和静态预警,并以济南市东城区为例进行应用。应用中统筹考虑了水质与水量对预警级别的影响,并给出了相应的预警方案。更多还原

【Abstract】 The contradiction between water supply and demand in North China is prominent. It is especially important to establish a regional water resources pre-warning mechanism. In this paper, the non-flood period is used to propose a method of delineating the warning line and pre-warned zone based on the water quantity and coupling of water quantity and water quality. By taking into account the length of the pre-warning period, it is divided into point warning and process warning. At the same time, the impact of precipitation on the early warning level is considered during the pre-warning period, it is divided into dynamic pre-warning and static pre-warning. This paper takes the East District of Jinan City as an example to apply water resources pre-warning. The application has taken into account the impact of water quality and quantity on the warning level and given a corresponding pre-warning plan.更多还原
