问题选择题

每年11月后我国东部沿海某些地区常有咸潮发生，2013年11月初，珠江三角洲又开始有咸潮危害，回答下列问题。（）

小题1:咸潮多发生在沿海（）

A．过度抽取地下水的地区

B．上游水库开闸放水，增加河流入海量

C．治理水污染，减少污水排放

D．减少抽取地下水，多用河水做水源

答案

小题1:C

小题2:B

题目分析：

小题1:当淡水河流量不足，令海水倒灌，咸淡水混合造成上游河道水体变咸，即形成咸潮，所以咸潮发生在河流入海口地区。故选C。

小题2:因咸潮的形成是因河流流量不足，而引起海水倒灌，所以减缓措施应在河水不足时补充河水，所以上游水库开闸放水，增加河流入海量，能阻止海水倒灌；而修筑堤坝，阻挡海水入侵同时，也阻挡了河水入海，会引起洪涝灾害；减少抽取地下水，多用河水做水源，会使河流水更少，加重咸潮。故选B。
