Study on the dynamic characteristics of shallow groundwater level under the influence of climate change and human activities in Cangzhou, China

Based on the monitoring data of groundwater level, mining data and meteorological data from 1986 to 2015 in Cangzhou City, the change characteristics of depth of groundwater level were studied. On this basis, the nonparametric statistical test method (Mann–Kendall method) was used to study the trend...
