下图为“新疆和田地区人口增长、耕地扩大所产生的影响关联图”,读图完成1~2题。

1.图中,甲表示(  )

A.土地盐渍化                         B.下游河流水位上升

C.下游河流流量减少                   D.流动沙丘向绿洲侵袭

2.导致图示区域荒漠化问题加剧的人类活动原因有(  )

A.①③⑤                   B.②③④

C.①④⑥                   D.③⑥

 

答案

1.C   2.B

 

从图中地理事物之间的逻辑关系可以判断人口增长、耕地扩大带来的上游用水增加,会使下游河流流量减少。注意抓住题目中问的是“人类活动”,燃料短缺、风沙侵袭、人口和贫困问题均不属于人类活动,因此只有B选项符合题意
