题目内容

【题目】2004年以来，我国城市化水平持续上升，同时粮食总产量连年增长。完成下列问题。

【1】我国粮食总产量连年增长的主要原因是

A．农业技术水平提高 B．耕地面积增加

C．交通运输条件改善 D．气象条件稳定

C．制约农业劳动力转出 D．阻碍商品农业发展

【答案】

【1】A

【2】B

【解析】

试题分析：

【1】城市化水平持续上升，耕地面积减少，则粮食总产量增长，主要是通过农业技术水平提高，单产量高导致的，与交通和气候变化关系不大，故A项正确。

【2】城市化水平持续上升，城市发展必须侵占耕地，不利于优质耕地的保护，故A项错误；城市化快速发展，促使农村剩余劳动力大量转出，从事农业人口减少，有利于农业规模化经营，利于商品农业发展，故B项正确。
