问题 综合

图Ⅰ为某区域示意图,图Ⅱ反映图Ⅰ中的P地河谷剖面,P地河谷剖面的形成与地转偏向力的作用有关,图Ⅲ反映图Ⅰ对应的湖泊情况,回答下列问题。

图 Ⅰ                       图Ⅱ                    图Ⅲ

(1)图Ⅰ的河流流向是          ;P地附近的地质构造是              

(2)若在P处建大坝,对Q处河流的水文特征可能产生哪些影响?                   

                                     

(3)S城市的海滨浴场游客云集的季节,湖泊蓄水范围接近图Ⅲ a、b中的      ,从科伦坡驶往孟买的轮船航向与洋流流向的关系是                 

(4)简要评价R地气候条件对农业生产的影响。

                                                                                

                                                                       。

答案

(1)由南向北流     背斜

(2)流量的季节变化减小,河流含沙量减小。

(3)  逆水航行

(4)该地为温带海洋性气候,终年温和多雨,光热不足,不利于谷物生长,有利于多汁牧草生长,适合发展畜牧业。

(1)根据甲图等高线形态,河流流向与等高线弯曲方向相反,可判定河流由南向北流。根据乙图中岩层的弯曲状况,可判断河谷处的地质构造为背斜。

(2)P处建大坝,位于Q的上游地区,则对Q处河流的流量起到调节作用,使得流量的季节变化减小,上游河段泥沙在大坝内淤积一些,使得河流含沙量减小。

(3)从P地河谷剖面图可知,河水对河床的东岸冲刷明显,河流由南向北流,即受到向右偏的地转偏向力,该区域位于北半球,则S城市属于地中海气候,当该城市的海滨浴场游客云集的时候为夏季,夏季地中海气候区高温少雨,则湖泊的水量小,蓄水范围接近图Ⅲ中的a;该季节,北印度洋海区的洋流为顺时针流动,则从科伦坡驶往孟买的轮船航向与洋流流向的关系为逆水航行。

(4)R地的纬度高于40度,在大陆西岸,为温带海洋性气候,终年温和多雨,光热不足,不利于谷物生长,有利于多汁牧草生长,适合发展畜牧业。
