【題目】2014年2月10日,國家衛(wèi)計委宣布上海、江蘇等9個省份已通過備案,成為第一批實施單獨兩孩政策的省份。下圖是我國某省從建國初期至今的人口自然增長軌跡示意圖,其中階段為預(yù)測段。完成下列各題。

【1】關(guān)于圖中人口變化的描述正確的是

A.階段人口數(shù)量大于階段人口數(shù)量

B.階段會出現(xiàn)勞動力嚴重短缺問題

C.階段不會出現(xiàn)人口老齡化問題

D.拐點的出現(xiàn)主要是受政策因素影響

【2】該省實施單獨二孩政策以后,十年內(nèi)不會對以下各項中產(chǎn)生明顯影響的是

A.人口老齡化速度

B.勞動力的規(guī)模

C.嬰幼兒用品消費市場及相關(guān)產(chǎn)業(yè)

D.醫(yī)療教育等公共資源

【答案】

【1】D

【2】B

【解析】

試題分析:

【1】 讀圖,根據(jù)圖中曲線,Ⅱ階段的人口出生率大于死亡率,人口總數(shù)持續(xù)增大,所以I階段人口數(shù)量于Ⅱ階段 ,A錯。Ⅱ階段人口自然增長率下降,但仍較高,不會出現(xiàn)勞動力嚴重短缺,B錯。Ⅲ階段人口老齡化問題仍較嚴重,C錯。拐點出現(xiàn)是嚴格的計劃生育政策,③拐點的出現(xiàn)主要是計劃生育政策調(diào)整,都受政策因素影響 ,D對。

【2】該省實施單獨二胎政策以后,出生率增加,人口自然增長率增加,人口老齡化速度會減明顯慢,A錯。但十年內(nèi)新增人口不會轉(zhuǎn)化成勞動力,不會影響勞動力的規(guī)模,B對。人口自然增長率增加,嬰幼兒用品消費市場及相關(guān)產(chǎn)業(yè)有明顯發(fā)展,C錯。人口增長,醫(yī)療教育等公共資源增加明顯,D錯。
