树有根,水有源,地下水是地上渗下去的,没有别的途径。但是现在,只要我们到街上看一看,就会发现到处是柏油路或水泥砖覆盖的路面,令人不解的是,就连河道都要用水泥砖将其砌死。我们把水系所必须的循环通道全部堵死,雨水被我们人为地流进了污水管道,然后白白地汇入海洋,这到底是为了什么?放着可惜与否先不说,关键是我们没有这么多水可以白白浪费。目前北京城区的路面不是水泥就是柏油,河道本来接纳了这些固化的地面流下来的雨水,也只有河道这惟一的水循环通道给水留下了一点点回灌地下的余地,如今却被用衬砌的方式堵死了,看着到是好看了,但是我们的首都今后的地下水怎么办? Trees have roots, water is active, groundwater seeps on the ground, there is no other way. But for now, as soon as we look in the street, we find pavements covered with tarmac or cement bricks.

Only the water channel of the river channel left little room for water recharge, but now it is lined with lining Blocked, looked good, but what about the underground water in our capital?
