下图为乌拉尔河水系示意图,①②③为三个水文观察站。读图回答下列问题。

小题1:根据图中信息,推断乌拉尔河的主要补给水源是(  )

A.季节性积雪融水

B.永久性冰川融水

C.雨水

D.地下水小题2:下列关于乌拉尔河的叙述,正确的是(  )

A.直接参与海陆间水循环

B.河流径流量从上游往下游逐渐增大

C.蒸发旺盛导致①处径流量小

D.②至③河段支流汇入少,下渗量大

答案

小题1:A  

小题2:D

题目分析:

小题1:由图中径流量比例可看出,乌拉尔河4—5月份径流量最大,出现春汛,且乌拉尔河发源于乌拉尔山,山地积雪较多,春季气温回升,积雪融化,可知其主要补给水源为季节性积雪融水;永久性冰川融水出现在夏季;该地以温带大陆性气候为主,降水较少。

小题2:乌拉尔河发源于乌拉尔山,注入里海,属于内流河,故其参与陆地内循环,A错;由图中水文站年径流量可知,乌拉尔河径流量从上游往下游先增加后减小,B错;①处纬度高,气温低,蒸发量小,C错;由图中可看出,②至③段支流汇入少,且该地以温带大陆性气候为主,气候干旱,下渗量大,D正确。
