第16週-段落翻譯

p.102

Coastal deltas and wetlands and inland floodplains are important parts of the earth's natural capital.They absorb and slow the velocity of floodwaters from coastal storms,hurricanes,and tsunamis.Unfortunately,human activities have degraded and destroyed these natural protectors of coastal communities.Such destruction played an important role in increasing the damage to the U.S city of New Orleans,Louisiana,when it was flooded by Hurricane Katrina in 2005.

As streams flow downhill,they shape the land through which they pass.Over millions of years,the friction of moving water may level mountains and cut deep canyons,and rock and soil removed by the water are deposited as sediment in low-lying areas.

沿海三角洲、沼澤地和內地洪泛區是地球自然資本的重要部分。他們可以吸收且減慢從沿海所形成的風暴、颶風和海嘯帶來的洪水。不幸地,人類的活動毀壞了沿海社區的那些自然保護者。這種破害對美國路易斯安那州的紐澳良市在2005年被颶風克脆那洪水淹沒時所增加的破壞扮演重要角色。

當溪流向下流,它們會塑造他們所穿過的土地,過了好幾萬年,移動的水所造成的摩擦,也許會形成水平山和切開深峽谷,且晃動並使土壤隨著水被沉澱在低區域。
