Distinction Between Sea Salt and Lake Salt Resources

(1) Characteristics of sea salt resources The surface-layer salinities of the offshore waters of China interpret a distribution regularity: low in near-shore zones, utmost in open sea atomic number 18as and even higher in Kurushio zones, and have a close relationship with seasons: high in winter and low in summer. In winter, the surface-layer seawater salinities norm 31.5¡ë in the Bohai ocean, 34¡ë in its central check and little than 26¡ë in its coastal zone; they ar in the range of 31¡ë~32¡ë in the northeastern part of the Yellow Sea and 31.5¡ë~32.5¡ë in the southern part; they argon 33¡ë~34¡ë in the most part of the eastern United States China Sea, lower than 20¡ë in the area of the Yangtze River estuary, and 34.5¡ë in the zone the Kuroshio flows through. In summer, they average 25¡ë~30¡ë in the Bohai Sea and 30¡ë~32¡ë in the Yellow Sea, and are the lowest, down to below 5¡ë, at the Yangtze River estuary but carry on to be around 34¡ë in the Kuroshio zone of the atomic number 99 China Sea. The seawater salinities along the coast of China switch in the range of 26.0¡ë~31.0¡ë in the Bohai and Yellow Seas, 24.0¡ë~32.0¡ë in the vitamin E China Sea and 27.0¡ë~34.0¡ë in the South China Sea, and they are very low in all estuary areas. Chinas coastline consists of 3 lineaments of coasts. The first type is plain coasts, i.e.

, the continental coasts of the Bohai and Yellow Seas distributed to the north of the Hangzhou Bay. They are mostly made up of enormously dense but loose sandy or silty sediments, belong to the puddly coast, and are favorable for constructing large and medium-sized saltfields. The second type is embayed coasts, which are mainly distributed along the East China Seas continental coasts of Fujian and Zhejiang Provinces to the south of the Hangzhou Bay. They are mostly composed of bedrocks and wherefore are also called bedrock coasts. Coasts of this type are characterized by indented fjords, eminent slopes and great water depths but along them there embody plain type coasts of small sizes in river-mouth areas...
