我国濒临的海洋是一个大盐库,沿海很多海滩是良好的日晒制盐场地。北起辽东半岛,南至海南岛,盐场星罗棋布,其中以渤海湾的长芦盐场,江苏的淮北盐场和海南岛的莺歌海盐场最为著名。在我国西部和北部内陆地区,还有许多盐湖,也蕴藏着十分丰富的原盐资源。我国盐业生产发展很快,现年产已达2500万吨,居世界第一位,无限广阔的盐田是一种特殊的水域生态系,它不是一个单一的稳定生态系,在日晒制盐过程中,盐度由低到高,直到结晶池,是一个水质环境逐步变化的生态系统序列。在从低盐到高盐的水流过程中。紧 China’s verge of the ocean is a large salt reservoir, many beaches along the coast is a good sun and salt. From Liaodong Peninsula in the north to Hainan Island in the north, the salt fields are dotted with Changlu saltworks in Bohai Bay, Huaibei Saltworks in Jiangsu Province and Yinggehai Saltworks in Hainan Island. In China’s western and northern inland areas, there are many salt lakes, but also contains a very rich source of salt. China’s salt industry has witnessed rapid development. Now it has an annual output of 25 million tons, ranking the first in the world. The immense salt fields are a kind of special water ecosystem. It is not a single stable ecosystem. During the process of sun-salt making In the salinity from low to high, until the crystal pond, is a gradual changes in the water quality of the ecosystem sequence. During the flow from low to high salt water. tight
