全球性气候变暖将加速海平面的升高。对于这一趋势,沿海地区将面临两种基本选择:从海边向内陆退去或是积极地设法抗御海水的“侵略”。海洋与人类的生活息息相关,尤其对生活在沿海地区的人们影响更大。海洋在一定程度上影响着人类的居住状况和耕地面积,影响着三角洲和港湾地区经济的繁荣,影响着淡水资源。根据历史记载,地球海平面的升降变化一直不大。随着全球气候的变暖,热气流的渗透力增强,预计100年后,地球的平均温度将升高5.2—5.5℃。受此影响,地球表面的水将发生热膨涨,高山与极地的冰川将会融化,海平面将上升。虽然还无法预测其上升速度,但大多数沿海地区国家的海岸环境将遭到破坏,经济上将受损,这是肯定无疑的。 Global warming will accelerate sea-level rise. There are two basic choices for this trend in the coastal areas: going back inland from the seaside or actively trying to resist the “aggression” of seawater. The oceans are closely linked with the life of mankind, especially those living in the coastal areas. To a certain extent, the oceans and seas affect the living conditions and cultivated area of ​​the people, affecting the economic prosperity in the delta and harbor areas and affecting the freshwater resources. According to historical records, the elevation of the earth’s sea level has not changed much. As the global climate warms, the penetration of hot air currents increases. It is estimated that after 100 years, the average temperature of the earth will increase by 5.2-5.5 ° C. Affected by this, the water on the Earth’s surface will thermally expand, the glaciers in the mountains and polar regions will melt, and the sea level will rise. Although the rate of increase can not be predicted, the coastal environment in most coastal areas will be destroyed and economically damaged. This is undoubtedly the case.
