题目内容

【题目】 “三十年河东,三十年河西”常用来比喻世事变化、盛衰无常。历史上,我国某河中下游泥沙淤积严重、河床增高、洪水泛滥改道后,一个村子以前在河的西岸,后来变到东岸。

据此完成下面小题。

1这条河流有可能是

A.珠江B.塔里木河C.黑龙江D.黄河

2从根本上治理河流泥沙淤积、泛滥的措施是

A.跨流域调水B.修建水库C.植树种草D.加高河堤

【答案】

1D

2C

【解析】

根据黄河是我国第二长河,也是世界著名大河之一;它源自巴颜喀拉山,流经青海、四川等9省区,注入渤海,全长5 464千米,流域面积75.24万平方千米,进行分析解答。

1读材料分析可知,这条河流有可能是黄河,因为黄河流经黄土高原,水土流失严重,大量泥沙进入黄河,淤积河床,下游成为地上河,下游因河水泛滥而数次改道,一个村子以前在河的西岸,后来变到东岸。依据题意。故选:D

2读题干可知,该河是黄河;黄河中游流经黄土高原,由于水土流失严重,使大量泥沙在下游淤积,形成了举世闻名的“地上河”。因此从根本上治理黄河下游因河水泛滥而数次改道的问题,必须在上中游地区大力植树种草,保持水土,综合整治。故选:C

考查黄河的概况,要理解记忆。
