摘要
选取太原市冲积平原具有代表性的潜水水位监测资料,通过线性倾向估计和Mann-Kendall检验方法识别地下水位的趋势性、持续性和突变性。结果表明:城北和西谷水位年际波动较小,而南固碾、大井峪、良隆3站水位波动较大;大井峪、城北、良隆站地下水位表现为下降趋势,大井峪下降速率最大(为0.49 m/a),城北下降速率最小(为0.02 m/a),良隆站下降速率为0.36 m/a;南固碾和西谷站地下水位呈上升趋势,上升速率分别为1.09、0.06 m/a;通过M-K法检验,良隆站下降趋势显著,南固碾、大井峪、城北、西谷站趋势不显著;南固碾、大井峪和西谷站突变开始时间分别为2006年、2002年、2003年,城北、良隆站没有突变点。
This paper selected the representativephreatic water lever data of 5 monitoring stations in Taiyuan alluvial plain area. It identifiedthose data’s trend, persistence and mutation by using linear trend estimation and Mann-Kendall mutation test method. The results show that the groundwater level in Chengbei and Xigu stations is less fluctuated, while the water levels of Nangunian, Dajingyu and Lianglong stations are higher; the trends of groundwater level are declining in Dajingyu, Chengbei and Xigu stations and the decreasing rate is 0. 49 m/ a in Da-jingyu where the rate is the greatest; the least decreasing rate is 0. 02 m/ a in Chengbei, while it is 0. 36 m/ a in Lianglong Station; Nangunian and Xigu stations show rising trend with the rate of 1. 09 m/ a and 0. 06 m/ a respectively; the M-K mutation test shows that the decline trend of Lianglong Station is significant, while the trends in the rest of stations are not significant. The mutation times in Nangunian, Dajingyu and Xigu stations occur in 2006, 2002 and 2003 respectively, while Chengbei and Lianglong stations have not mutation points.
