摘　　要：肇州县是黑龙江西部重要的旱田灌区,农业灌溉主要依赖于地下水,地下水动态分析是灌区地下水承载力评价的基础和前提。对26眼长期观测井及85眼统测井数据进行了时空动态分析。通过分析指出,肇州旱灌区地下水动态类型以人工开采型为主;以6眼典型监测井为例,在作为平水年的2012年,多数井6月地下水水位达到年内低值,11月地下水水位达到年内高值,次年规律相同,灌溉取水对地下水影响强烈;在1980—2012年,区内地下水水位呈整体下降趋势,平均降幅为0.18 m/a,逐年增加的地下水开采量直接导致了的地下水水位下降;当前区域地下水水流向大致是东北至西南向。Zhaozhou County is an important drought-irrigation area in the west of Heilongjiang . Agricultural irrigation depends on the groundwater .In order to evaluate and predict the groundwater resources in drought-irrigation area of Zhaozhou , the dynamic analysis of groundwater is needed .In this paper , Zhaozhou County as the research area, analyses the data of 26 long-term observation wells and 85 wells.In 2012, for the six typical wells, the value of groundwater level is lowest in June , groundwater level reached the highest value in November , and it has the same regular pattern in next year .The influence of irrigation water on the groundwater is strong .In Zhaozhou , the groundwater dynamic type is mainly the artificial exploitation type , and some areas are the radial flow type .From 1980 to 2012 , the groundwater level in Zhaozhou County was decreasing year by year .The range of groundwater change is 0.18 m/a.The decisive factor of the decline of the groundwater level is groundwater exploitation increasing year by year .The groundwater flow direction is roughly northeast to southwest .
