摘要：根据乌兰布和沙漠东北部人工绿洲2006—2012年10眼地下水位观测井资料,利用传统统计学对该地区地下水位时空变化动态进行了研究。结果表明,近7年来不同灌溉区地下水位动态变化呈现不同的规律:(1)黄灌区比井灌区及荒漠区地下水位均高。与荒漠区相比,第一、第二实验场黄灌区地下水位平均高出3.543m和3.316m,而井灌区则低出0.792m。从空间位置看,地下水位东南高,西北低。(2)黄灌区年内地下水位变化相似,均为1—3月,地下水位持续下降,4—10月,地下水位抬升,并在抬升中有回落;而井灌区与黄灌区不同,从1月开始,地下水位持续下降,至8月达到一年内地下水位埋深最深处,随后又缓慢上升。第二实验场荒漠区,年内地下水位基本不随月份的变化而变化。
According to the groundwater observational data about 10 wells which were distributed at Artificial Oasis in Northeastern Ulan Buh Desert from 2006 to 2012, temporal dynamics of groundwater level by using traditional statistics were studied. Result shows that： there are different dynamics rules existed in different regions over the past seven years. （1） The groundwater level of Yellow River Irrigation Area is higher than that of well-irrigated are- a ~ desert areas;underground water level of First ~ Second Experimental Site in Yellow River Irrigation Area is 3. 543 m ~ 3. 316 m higher than that of desert area,respectively;level of well-irrigated area is 0. 792 m lower than that of desert area;the spatial distribution of groundwater level is Southeast being higher ~ Northwest being lower. （2） The changes of groundwater in Yellow River Irrigation Area are similar in the very year,being January - March; groundwater level of Yellow River Irrigation Areas continued to decline in the first three months, and rose from A- pril to October, and then declined. Groundwater level of well-irrigated area continued to decline from January, which achieved the lowest in August, and then slowly rose, reached the deepest groundwater depth in August in one year;at the Second Experimental Site,groundwater level of desert areas didn＇t change within one year.
