解决海平面上升对农业影响问题
Solve the effect of rising sea level on agriculture

    海平面上升的潜在威胁,万万不可小视。科学家预测到2050年,我国海平面要上升6—26厘米,到21世纪末将达到30–70厘米。据科学家估计,当海平面上升1米时,我国沿海将有12万平方千米土地被海水淹没,占我国国土面积的12.5%,而且有7000万人需要内迁。到那时,像上海、天津、广州这些大城市都将受到威胁。
    人造耕地选址时,要求地面高程大于70米。这样的高度,即使南极大陆、北极陆缘、格陵兰和青藏高原的冰川全部融化,海平面上升也淹不着人造耕地。海平面上升对农业影响问题就这样解决了。

 

解决海平面上升对农业影响问题
Solve the effect of rising sea level on agriculture

    The problem of rising sea level is a potential threat for agriculture which is not to be neglected. Scientists predict that by 2050 rising sea level will reach 6-26 cm and by the end of this century will reach 30-70 cm. According to scientists' estimation when sea level will has risen up by 1 meter, 120000 square meters of land on shore will be flooded by sea water in our country, which covers 12.5% of our national territory and 70 million people will be moved towards the inner land. At that moment many cities such as Shanghai and Tianjin and Guangzhou will be threatened.
    The sites to be chosen for artificial cultivated land have been considered. The altitude should be higher than 70 meters. For such height even though the glaciers on the Antarctic continent and continental edge around the Arctic as well as Greenland and Tibet are thawed, the artifical cultivated land will not be covered by sea water. So we say that the rising sea level effects on agriculture will be solved easily.
