开发新水源,是解决水危机的一个重要途径。面对咸苦浩瀚的大海,人们在望洋兴叹之余,肯定不止一次地幻想过:海中有没有淡水?能不能像钻探石油那样从海底下钻出淡水来?在波斯湾边巴林群岛,曾经用竹管从海底的涌泉汲取淡水;希腊东边的爱琴海中,也有一处涌泉,一天出淡水100万立方米,人们将泉水与海水分开,用泉水灌溉了3万公顷的土地。近来,俄罗斯海洋学家探测表明,大洋底部淡水资源很丰富,其蕴藏量约占海水总量的1/5。 Developing new water sources is an important way to solve the water crisis. In the face of the vast and salty sea, people are overwhelmed by the ocean and certainly have more than once imagined: Is there any fresh water in the sea? Can we drill fresh water under the sea like drilling oil? In the Gulf of Bahrain along the Persian Gulf, The tube draws fresh water from the seafloor springs; there is also a spring in the Aegean Sea to the east of Greece, where one million cubic meters of fresh water a day is shed, separating the spring from the seawater and irrigating 30,000 hectares of spring water. Recently, Russian oceanographers detected that freshwater resources at the bottom of the oceans are abundant, accounting for about 1/5 of the total amount of seawater.
