我国海盐盐田的总面积为3400平方公里,已占全国海涂面积的17％,为海水化学资源的开发利用提供了广阔的基地。在目前我国财力有限的条件下,我国海水化学资源的开发应当与海盐生产密切结合,借助海盐生产现有人力、物力、财力开展海水化学资源的开发研究。海水中含有的元素很多,随着科学技术的发展,从海水中提取的各种有用物质日益增多,但迄今为止,直接从海水中提取的物质并已达到工业化水平的,只有镁和溴两种元素。这两种
The total area of China’s Haiyan Yantian is 3,400 square kilometers, accounting for 17% of the total area of the national sea-coated area, providing a vast base for the development and utilization of seawater chemical resources. At present, under the condition of limited financial resources in our country, the development of marine chemical resources in China should be closely integrated with the production of sea salt and the development of seawater chemical resources should be carried out with the help of manpower, material resources and financial resources of sea salt production. There are many elements contained in seawater. With the development of science and technology, there is an increasing amount of various useful substances extracted from seawater. However, only substances that have been extracted from seawater and have reached the level of industrialization so far have been only magnesium and bromine element. These two
