中国海与现代科学技术

中国既是一个大陆国家又是一个海洋国家，约３００万平方公里的海域与６５００多个岛屿如同陆地资源一样为中国人民提供了舟辑之便与渔盐之利，还蕴藏着丰富的矿产资源。

CHINA SEA AND MODERN SCIENCES & TECHNOLOGY

China is not only a continenta1 but also an oceanic country, with about 3,000,000Square kilometers sea area and 6,500 islands,which, just as the land resources, supplies the Chinese peop1e water transportation, dieting salt and rich mineral potenhals. The Law of the Sea of the United Nations established after about 10 years discussion. It gave us lawyal tools to protect our sovereignty of sea region. Temporary, it asked China to detect the environment, resources by modern sciencestechnology,and to understand refated lawyal items and history of international re1ationship for supplying the reliable data to determine the sea region draft. The sea marine space includes the interactions or hydrosphere and atomosphere at water and air surface,of water and rock at the sea bottom, etc. Yet,ocean is the the gcnerahon place and experiment sites of modern sciences. The Plate tectonics is generated from ocean. It also containsalmost all kind of resources had been found and has it's own characters.Sea environment related the transportation and any kinds of marine acivities. It demands all days environment monitoring. The navigating and positioning had passed the compass,magneticcompass, gyrocompass and GPS periods.Sea environment monitoring factors includes ocean atmospheric factors, physicalocean factors and ocean pollution factors.The key technique is to develope a series of envlroment sensors.Sea floor geomorphology can be made by geophysical methods. It has very specialized topography and polymatallic nodules with many kinds of metals.The mantle geological structure is different with continent. There are rich oilgas in the continent shelf of the ocean.The basic tools to develope oil&gas are geophysical methods, such as gravity, magnetic methods, seismic and well logging.It will create a large scale and key roll playing industry to develope China sea. It's our responsibility and duty to defense the China Sea.
