In a natural ecosystem, rainwater is soaked up by soil and vegetation,
在自然生态系统中,雨水被土壤和植被吸收,
the majority then evaporates and the rest filters deeper into the ground. The evaporating water then cools the surroundings.
随后大部分被蒸发掉,剩余的渗入更深的土壤层。蒸发掉的水分也带走了周围环境中的热量。
Cities disrupt this system. Water can’t soak through the concrete and is piped away.
城市扰乱了这个系统。水无法渗透混凝土,只能顺着管道流走。

This is Rummelsburg, in East Berlin. Built 20 years ago, it’s become a large scale example of the Sponge City concept.

It’s like a sponge and it soaks the water during heavy rainfall and then it’s used by the plants, so they take all the water and finally evaporate it.
它就像一块海绵,在强降雨时吸收水分,供植被使用。所以,它们可以吸收掉所有的水分,并最终将其蒸发。
