一、水质决定水的使用价值《水利经济》发表了不少论述水价的文章。大多只考虑水通过位移供应到用户的价格,忽略了水质的价格。海水有利于远洋航运,海边沙滩适合于海水浴,海水也可以作为制盐的原料。就这个范围讲。海水有一定的使用价值。但海水不宜于农田灌溉,更不能饮用。因为不能作为商品,也就没有价格。淡水用途较多,但黑臭的渠道水只能使用于航运,不宜饮用。当淡水受到重金属和有毒工业废水污染时,也不宜于农田灌溉。因此,黑臭有毒的淡水不能作为商品。
First, the water quality determines the value of water “Water Economy” published a lot of articles on water prices. Most consider only the price of water supplied to the user through displacement, ignoring the price of water quality. Sea water is conducive to ocean shipping, sea beach suitable for sea water bath, sea water can also be used as salt raw materials. Speaking on this area. Sea water has some use value. However, seawater should not be irrigated in farmland, but should not be consumed. Because can not be as a commodity, there is no price. Fresh water uses more, but black smelly channel water can only be used for shipping, should not drink. When freshwater is contaminated by heavy metals and toxic industrial waste water, it is also not suitable for farmland irrigation. Therefore, black and poisonous freshwater can not be used as a commodity.
