| 摘 要： | 中国已决定在3年之内把目前严重偏低的供水价格提高到保本乃至微利水平,这意味着华北地区农业供水价格将从目前的0.03元/m3左右提高到0.2元/m3～0.3元/m3,工业用自来水价格将从0.50元/m3～1.50元/m3提高到3.0元/m3～4.0元/m3,生活用水价格将从0.30元/m3～1.00元/m3提高到1.00元/m3～2.50元/m3。如此大幅度地提高水价,将对华北地区的水资源需求产生强烈的抑制作用,相对于原来预测的水资源需求量,水价提升将使水资源需求量减少25%～50%,达132～250亿m3,至少相当于“南水北调”中线和东线两项工程调往黄河以北的水量。显然,理顺水价具有很大的节水潜力。

| Abstract: | It is planed that the water price which is much lower than Supplying cost now will be rised to cost or meager profit level by 2000. It means the price of irrigation water will rise from 0.03￥/m3 to 0.2￥/m3-0.3￥/m3, that of tap water used for industries will be rised from about 0.5￥/m3-1.5￥/m3 to 3.0￥/m3-4.0￥/m3, and that of tap water used for living will be rised from 0.3￥/m3-1.0￥/m3 to 1.0￥/m3-2.5￥/m3. This strong price rising will decrease violently in the water demand in North China. The total water demand will decrease about 25%-50%, i.e., 132×108m3-250×108m3, which is more than the total amount transferred across Yellow River by the"Medium line" and the "East line" "Water Transfer Projects From Yangtze River to North China". |
