我国华北地区严重缺水。京津地区和河北省有我国的政治中心、工业重镇和重要的粮棉基地。然而,由于缺水已经制约了工农业的发展和人民的生活。万一再遇到几年连续干旱,将会造成我国国民经济的重大挫折,不能不早作准备。怎样解决这个问题呢?我们首先考虑到的是节水。这些年来,京津冀对节水已做了大量的工作。有些工厂已做到用水量不变而产量翻番。但是节水也需要大量投资,需要运行费用。据河北省资料,全省农业节水需投资26.5亿元,仅能达到年节水17亿立方米。平均单方水需投资1.56元,单方水成本 0.13元。工业节水投资可能更高。
There is a serious shortage of water in North China. The Beijing-Tianjin region and Hebei Province have China’s political center, industrial center and important grain and cotton bases. However, due to lack of water, the development of agriculture and industry and the people’s life have been restricted. In the event of successive successive years of drought, it will cause major setbacks in our national economy and must not be prepared in advance. How to solve this problem? We first consider saving. Over the years, Beijing, Tianjin and Hebei have done a great deal of work on water conservation. Some factories have doubled the amount of water they produce. However, water-saving also requires a lot of investment, the need for operating costs. According to information from Hebei Province, the province needs 2.65 billion yuan in water-saving agriculture and can only save 1.7 billion cubic meters of water a year. The average single-party investment of 1.56 yuan water needs, one-party water costs 0.13 yuan. Industrial water saving investment may be higher.
