“God made the world,but the Dutch made Holland.” True to this saying,the people of the Netherlands are again “making” their land.
About 1980 the Netherlands will complete a project begun in the 1920’s:transforming the Zyuder Zee,an inlet (小港) of the North Sea into dry land and a freshwater lake.By stages,550,000 acres of land will serve several purposes:industrial,recreational,military,and agricultural.Fed by the river Yssel,the remaining water basin Lake Yssel,about 300,000 acres will irrigate the surrounding land and help in the fight against salination (盐化作用).Excess water will drain through sluices into the sea.
As the first stop a nineteen-mile-long barrier dam,rising twenty-five feet above sea level,closed the entrance to the Zuider Zee.Then the experimental polder of a hundred acres preceded the first and smallest of the main polders fifty thousand acres that became dry land in 1930.The fifth and largest polder 150,000 acres will be the last of the Zuider Zee works.
Farmers for the new polder (开拓地) come from every province.The Eastern Flevoland polder,completed in 1957,became farmland for many from the province of Zealand which was badly hit by the disastrous floods of 1953.
