Fig. 6: Dynamics of groundwater elevation of irrigation wells from 2000 to 2017.

From: Climate adaptation through rice northward expansion aggravated groundwater overexploitation in Northeast China

Fig. 6

Box plots show the groundwater elevation for all wells each year, including the minimum, first quartile, median (solid line), third quartile, and maximum values. Black points show the mean values of groundwater elevation of the well for each year. The Red dashed line means the trend of mean groundwater elevation of wells with years using a regression model. ** means the trend of groundwater elevation is significant at the level of 0.01.
