针对目前地下水位警戒线确定方法少、确定出的警戒线简单问题,以胶南市风河地下水源地为例,考虑有效降水的影响,应用多元回归方法对降水量、取水量与地下水位变化三者之间的关系进行了拟合分析,提出了静态警戒线和动态警戒线的基本概念和确定方法,并对未来1、2、3个月的地下水位预警可确定出红、橙、黄三条警戒线。结果表明,对于不同降水频率的年份,各月的地下水位动态警戒线不同,最高警戒水位为静态警戒线,最低警戒水位为基准水位;在对地下水的实际预警管理中,应以动态警戒线作为预警管理指标并进行灵活调控。
Aiming at the simple problem of determining the warning line of the groundwater level and the simple warning line, the paper takes the groundwater source of Fenghe in Jiaonan City as an example to consider the effect of effective precipitation. Using the multiple regression method, the variation of precipitation, water withdrawal and groundwater level Fitting and analyzing the relationship between them, and put forward the basic concepts and determination methods of static warning line and dynamic warning line, and determine the red, orange and yellow of the groundwater level warning in the next 1, 2 and 3 months Cordon. The results show that for different years of precipitation frequency, the monthly groundwater level dynamic warning line is different, the highest warning water level is the static warning line and the lowest warning water level is the reference water level. In the actual warning management of groundwater, dynamic warning line should be taken as Early warning management indicators and flexible control.
