(4)地上河 流速變緩,泥沙大量淤積 治理中游水土流失,疏浚河道

【解析】

試題分析:本題考查黃河的基本概況。(1)據(jù)圖可知A是黃河最大支流,為渭河;B位于山西省,故其為汾河;(2)寧夏平原和河套平原,被稱為塞外江南,黃河水是其主要的灌溉水源;工業(yè)城市比較多,故其工業(yè)用水量也大,故黃河流經(jīng)寧夏平原和河套平原的水量減少較多。(3)黃河中游黃土高原水土流失嚴(yán)重,治理的生物措施主要是植樹(shù)造林,工程措施采用打壩淤地、修建小型的水庫(kù)等。(4)黃河下游為地上河,形成其主要原因是水流變緩,黃河夾帶的大量的泥沙,在下游大量沉積于河床形成的。改造的主要措施為治理黃河中游的水土流失,結(jié)合疏浚河道進(jìn)行治理,效果較好。
