Abstract:
Groundwater is an important water source of Jinghuiqu Irrigation District. The analysis of its dynamic characteristics provides important guidance to the development and utilization of water resources. Based on the groundwater depth data of Jinghuiqu Irrigation District during 1981-2010, we analyzed its interannual variation using linear tendency estimation method, cumulative departure, Sen slope estimation method, and Mann-Kendall trend test. We analyzed the mutation of groundwater depth using smoothing T test and two- dimensional regression mutation analysis. We determined the most important influence factors of groundwater depth using principal component analysis and grey relationship analysis. The results showed that the groundwater depth tended to increase during 1981-2010. The mutation happened in 1994. Before 1994, evaporation was the most important influence factor of groundwater depth. After 1994, the most important influence factors became evaporation, groundwater extraction, and canal water diversion.
