在相当长的时期里,水被看成是取之不尽、用之不竭的自然资源,人们只承认水所具备的自然属性,而忽视了其商品属性。近年来,相当于农业生产而言,水资源日益稀缺,在短缺的同时,由于灌排方式的粗放,仍然存在着水资源的严重浪费,造成浪费的一个重要的原因就是供水水价的普遍偏低。文章通过对灌溉水价的选择分析,指出了按供水成本收费的合理性和必要性。 For a long time, water was regarded as an inexhaustible natural resource. People only recognized the natural attributes that water possessed, while neglecting the attributes of their goods. In recent years, as far as agricultural production is concerned, water resources are increasingly scarce. In the meantime, due to the extensive drainage system, there is still a serious waste of water resources. An important reason for the waste is the generally low water price . Through the analysis of the choice of irrigation water price, the paper points out the rationality and necessity of charging according to the water supply cost.
