塔里木沙漠南缘安迪尔河水文特征分析

Hydrological Characters of Andir River in Southern Tarim Desert

安迪尔河位于塔里木沙漠南缘,发源于昆仑山,上游河水沿河床大量入渗,中游为干河床,下游为泉水溢出补给型河流。安迪尔河缺乏水文资料,以临时水文站1998年实测水文资料为依据,对安迪尔河的水文特征进行分析,以便说明泉水型河流水文特征。分析了安迪尔河水位年内变化、冰期水位、畅流期水位、洪水期水位的变化特征;对安迪尔河水位-流量关系进行了分析,建立了相应的水位-流量关系方程式,并对冰期、畅流期的、洪水期逐日平均流量和流量特征进行了推求和分析,安迪尔河1998年泉水溢出量为0.5528亿m3。

The Andir river situates in the southern Tarim desert and originates from the Kunlun mountains. A great deal of river water infilter into below riverbed in upper reaches and replenish river as spring in lower reaches, so the middle reaches are zero flow riverbed. The paper analyzed the water level variations of Andir river in inner year, frozen period, unfrozen period and flood period; has established the equation of river discharge in relation with water level; besides, has deduced the daily mean discharge variations in frozen period, unfrozen period and flood period. It was calculated that the total spring output of Andir river was 0. 5528×10^8 m^3 in 1998.
