从60年代起,许多国家开始了海水淡化的研究。通常的做法是用传统的锅炉脱盐淡化法。有些先进的国家建起了巨大的核能淡化厂或者是太阳能淡化海水厂,但设备复杂,投资昂贵,成本太高。近十多年来,国外的一些植物学家又为海水淡化开辟了一条新途径——利用红树的吸盐功能使海水淡化。这种做法成本很低,又能美化环境。红树生长在中美洲及北美南部的气温较高地区,种类繁多,树体高 Since the 1960s, many countries started research on desalination. The usual practice is to use traditional desalination desalination boiler. In some advanced countries, huge nuclear desalination plants or solar desalination plants have been built, but the equipment is complex, the investment is expensive and the cost is too high. In the recent ten years, some foreign botanists opened up a new way for seawater desalination - desalination of seawater by using the salt absorption function of mangrove. This approach is very low cost, but also beautify the environment. Mangroves grow in high temperatures in Central America and southern North America, with a wide range of tree species
