【題目】山西某化工廠發(fā)生一起因輸送軟管破裂導(dǎo)致的苯胺泄漏事故，泄漏苯胺隨河水流出省外，處于受污河水下游的河北、河南兩省也受到影響，三省聯(lián)動應(yīng)急，截流治污。有專家說，影響中國經(jīng)濟的首要問題就是水。

據(jù)此回答下面小題。

【1】山西省、河北省及河南省主要的水資源來源于（ ）

A. 陸地上的冰川 B. 海洋水

C. 地下水、高山冰雪融水 D. 江河水

【2】上述水資源遭污染的地區(qū)，應(yīng)采取的必要措施是（ ）

A. 跨流域調(diào)水

B. 遷出河流兩岸的居民

C. 污水處理，暫停自來水供應(yīng)

D. 降低生產(chǎn)耗水，提高利用效率

【答案】

【1】 D

【2】 C

【解析】

本題考查我國水資源的相關(guān)知識。

【1】我國主要使用的淡水資源是江河湖泊水及部分地下水，山西省、河北省及河南省主要的水資源來源于江河水。故選：D。

【2】泄漏苯胺隨河水流出省外，使得受污河水下游的河北、河南兩省居民飲水安全遭到嚴重威脅，屬于河水污染，應(yīng)對癥下藥，進行污水處理，暫停自來水供應(yīng)。故選：C。

我國水資源的時空分布情況受我國降水的影響，我國降水空間上來說從東南沿海向西北內(nèi)陸降水逐漸減少，導(dǎo)致我國水資源東多西少、南多北少。
