摘　　要：针对目前地下水实际预警管理中存在预警期较短的问题,以胶南市风河浅层地下水源地为例,选择非汛期为预警期,在多元回归方法分析的基础上,对非汛期预警进行研究。提出了非汛期不同降水频率下红、橙、黄、蓝四条地下水位警戒线和相应预警区的确定方法,并对非汛期无降水、降水频率分别为95%、50%和5%四种条件下的非汛期初始地下水位进行了预警。结果表明,不同预警级别的初始地下水位警戒线和预警区的合理划定应综合考虑非汛期开采量和降水量;对非汛期初始地下水位进行预警时,预警程度随降水量的增加而降低。In order to solve the problem that groundwater early warning period is snort in pracncm warning manage- merit, taking Fenghe River shallow groundwater source area of Jiaonan City for an example, this paper studies the early warming of non-flood season based on the method of multiple linear regression analysis. Under the conditions of different precipitation frequencies in non-flood season, it proposes a method to determine the red, orange, yellow and blue alert lines and the corresponding alert intervals of groundwater level. In addition, early warning of initial groundwater level is performed at the conditions of non-precipitation, 95 % precipitation frequency, 50% precipitation requency and 5 % pre- cipitation frequency. It concludes that how to determine the alert lines and corresponding alert intervals should be consid- ered both groundwater exploitation and precipitation; besides, the alert extent will decrease along with increasing precipi- tation when making forewarning study on initial groundwater level in non-flood season.
