中国地质调查局日前公布了中国地下水资源的“底”,调查显示:全国目前仍有7000万人的饮用水不达标。这份调查显示:我国的地下水分布很不均匀。70%的水量分布在南方,由于南方使用的主要是地表水,因此南方地下水的开采潜力很大。而在北方情况却恰恰相反,北方城市主要采用地下水,? China Geological Survey recently announced the “bottom” of groundwater resources in China. According to the survey, there are still 70 million drinking water in the country that is not up to standard. The survey shows that: China’s groundwater distribution is very uneven. Seventy percent of the water is distributed in the south, and because of the predominantly surface water used in the South, there is great potential for exploiting groundwater in the South. In the north, on the other hand, the northern cities mainly use groundwater.
