Evaluating the Dynamics of Groundwater Depletion for an Arid Land in the Tarim Basin, China

摘要: Groundwater depletion has become a hotly debated topic, particularly in arid land. In this study, groundwater and its dynamic factors were investigated the Tarim Basin. The data collected randomly from 10 monitoring wells, September 2002–December 2014. Piezometric level decreased with range 667.00 cm to 1288.50 cm, also linear decreasing rate of 73.96 per year, on average. Significant spatial variation characteristics have been detected. was more serious northwest than southeast study area. A correlation analysis conducted explore major influence factors. These results showed that annual irrigated land area primary influencing factor. Driving force suggested electricity consumption could be an effective convenient factor assess exploitation. This indicated human activity impact for decline. seasonal-trend decomposition supported these findings, as observed variation. It provided new insight into time-series enhanced identification groundwater-flow characteristics. findings may useful understanding fluctuations high water demand regions developing safety policies management.
