摘要
Abstract
The causes for higher groundwater level in Yinbei irrigation region were analyzed, the annual and inner-year dynamic variation law
was studied. The main influencing factors on irrigation area groundwater level variation was determined by using principle component analysis
method. The results showed that the groundwater level has cyclicity and seasonal characteristics. Affected by random factors, the groundwater
level is relatively stable among years. The main factors for variation is induction water amount, degradation water amount a nd precipitation.关键词
