本文以翔实的国内外资料为依据,论述了我国开展大洋海底多金属结核开发研究的必要性、战略意义和可能性。 (一) 大洋海底多金属结核储量极为丰富地球上的海洋面积占地球表面的71％,其中79.4％的水深为2000 m～6000 m。在世界大洋中,有15％的深海底被富含锰、镍、铜、钴等元素的结核结壳复盖,其中可利用的元素除锰、镍、铜、钴外,铁、锌、钼、钒、铅、铂等也达到了可以综合利用的含量,是人类极为宝贵的矿产资源。据估计,全世界大洋底多金属结核的储量 Based on the abundant domestic and foreign materials, this paper discusses the necessity, strategic significance and possibility of our country to carry out the research on the development of polymetallic nodules in the oceans. (1) The reserves of polymetallic nodules in the ocean are extremely rich. The ocean area on Earth occupies 71% of the earth’s surface, of which 79.4% of the water depth is between 2000 m and 6000 m. In the world ocean, 15% of the deep seabed is covered by nodules rich in elements such as manganese, nickel, copper and cobalt. Among the available elements, manganese, nickel, copper and cobalt, iron, zinc and molybdenum , Vanadium, lead, platinum, also reached the content can be comprehensively used, is extremely valuable human mineral resources. It is estimated that the reserves of polymetallic nodules in the world’s oceans and seas are about the same
