一、“科技兴海”的战略作用 海洋对人类的生存发展有着非常密切的关系。海洋为人类提供了丰富的资源:能源、矿产资源、生物资源、海水资源、空间资源等等。 中国是一个海洋大国,有18000公里海岸线,约300万平方公里海域,相当于陆地国土面积的1/3,有6500个海岛,已发现的海洋生物就有20278种,其中鱼类有3014种,还有丰富的海洋油气和矿产资源等。 我国人口过度膨胀、资源短缺、环境恶化。据预测,我国的人口到本世纪末将达到13亿,下个世纪20～30年代可能达到15～16亿。要保证这么多人口的吃饭问题,一是要扩大耕地面积,提高单位面积产量,但提高单位面积产量是有限度的;二是向大海索取,这是最有
I. The Strategic Role of “Revitalizing the Sea by Science and Technology” The ocean has a very close relationship with the survival and development of mankind. The ocean provides abundant resources for mankind: energy, mineral resources, biological resources, sea water resources, space resources and so on. China is a large marine country with 18,000 kilometers of coastline and about 3 million square kilometers of sea area, equivalent to 1/3 of land area on land and 6,500 islands. There are 20,278 species of marine organisms found, of which 3014 species are fish, There is also a wealth of marine oil and gas and mineral resources. Our population is overpopulated, there is a shortage of resources and the environment is deteriorating. It is predicted that China’s population will reach 1.3 billion by the end of this century and may reach 1.5-1.6 billion in the next 20-30 years. To ensure the food for so many people, the first is to expand the area of arable land and increase the yield per unit area, but there is a limit to increasing the output per unit area. The second is to obtain from the sea the most
