【題目】造成我國東、西部地區(qū)人口分布差異的自然原因,敘述正確的是( )

A.西部地區(qū)氣候溫暖濕潤B.西部地區(qū)河流密布,水資源豐富

C.東部地區(qū)地形崎嶇,以高原、山地為主D.平原、丘陵主要分布在東部地區(qū),土壤肥沃

【答案】D

【解析】

我國已黑河——騰沖一線為界,此線以東的面積約占全國的43%,人口卻為全國的94.3%,而該線西部面積約占全國的57%,人口只有全國的5.7%,我國人口分布特點是東密西疏,人口地區(qū)分布很不均勻,東西部差異大。東部地區(qū)地形平坦,氣候濕潤,工農商業(yè)發(fā)達,交通便利。西部地區(qū)以高原山地為主,地形崎嶇,氣候干旱,工農商業(yè)落后,交通不便,所以東部地區(qū)人口多,西部地區(qū)人口少。

造成我國東、西部地區(qū)人口分布差異的自然原因是我國東部地區(qū)的地形以平原、丘陵為主,地形平坦,土壤肥沃,氣候溫暖濕潤,水資源豐富,適合人居;我國西部地區(qū)地形崎嶇,以高原、山地為主,氣候較干旱,水資源短缺,不適合人居住。故選:D
