【摘要】 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。更多还原

【Abstract】 At present,there are few studies on the methods to determine the alert lines of groundwater level and most results of them are rough.Taking Fenghe river groundwater source area of Jiaonan City as the object of study,this paper considers effective precipitation and applies multiple linear regression analysis method to fit the relationship among precipitation,exploitation and variation of groundwater level.On this basis,it presents the basic concepts and determining methods of alert lines of groundwater level in static and dynamic state.Then,it makes out the red,orange and yellow alert lines in terms of three different early warning periods including one month,two months and three months for early warning management.It concludes that the dynamic alert line of groundwater level of each month changes with annual precipitation frequency;the highest alert line of groundwater level is the static alert line of groundwater level and the lowest alert line of groundwater level is the benchmark level.It is advised to choose dynamic alert lines of groundwater level as guidance for fixable regulation in practical early warning management.更多还原
