降雨量对金山地区河道地表水位抬升影响显著,但由于受降雨强度、河道集水面积、持续时间、土壤饱和度、上游来水量等因子的影响,由降雨引起的水位变化形态复杂多样。为了能更简便直观的辨别降雨量对金山地区河道地表水位抬升的影响,本文根据2007~2013年廊下马家宅站和朱泾掘石港站降雨量及水位实时监测数据,采用相关分析法研究降雨量对金山地区地表水位抬升的影响,并通过部分异常值浅析河道水位异常变化的原因。
Rainfall has a significant impact on the surface water level rise in the rivers in Jinshan, but due to rainfall intensity, river catchment area, duration, soil saturation, upstream water inflow and other factors, the water level changes caused by rainfall are complex and diverse. In order to make it easier and more intuitive to discern the impact of rainfall on surface water level rise in Jinshan River, based on the real-time monitoring data of rainfall and water level in Langxia Majiazhai Station and Zhujing Nanshi Shigang Station from 2007 to 2013, the correlation analysis method was used to study the rainfall On the elevation of surface water level in Jinshan area, and the reasons for the abnormal change of river water level through partial outliers.
