摘　　要：研究区地处子牙河地下水系统上游,为典型冲洪积扇地貌,其地下水动态变化会对下游系统产生明显的影响。根据系统特征划分地下水动态类型为山前开采型和侧向补给—径流—开采型,研究地下水动态的变化特征和影响因素。结果表明研究区地下水补给、径流、排泄条件随地下水开采量、降雨量等因素发生变化,并可根据其变化规律推测下游地区地下水动态特征。The alluvial-fan of Ziya river system locates at the upstream of Ziya river groundwater system, is the typical alluvial-fan landscape , the variation of its dynamic can generate obvious influence to the downstream system .On the basis of system characteristic , the type of groundwater is divided into two parts ,piedmont mining type and lateral suppliesrunoff-mining type, and researched the change characteristic and influence factor of groundwater dynamic . The results show that the groundwater recharge, runoff and discharge conditions change with the variation of groundwater resources, rainfall factors, and then conjecture the regularities of dynamic characteristics of downstream system.
