水是人类生存的主要资源。我国是一个缺水的国家, 这是一个不争的事实。我国仅占世界水资源总量的7%,在世界银行资源统计的132个国家中,中国居第82位,人均占有量只有世界平均水平的31%。目前,我国半数以上的省市严重缺水。有关专家预测,到2010年,全国需水量为7000亿立方米,可供水量仅有6600亿立方米,缺水量400亿立方米。吉林省水资源总量404．25亿立方米,其中河川径流356．57亿立方米,地下水113．18亿立方米,人均占有地表水资源量 1526立方米,而全国人均占有量为2700立方米,水资源问题已经成为制约吉林省国民经济发展的重要因素。
Water is the main source of human existence. It is an indisputable fact that our country is a water-short country. China accounts for only 7% of the world’s total water resources. Among 132 countries in the World Bank’s resource statistics, China ranks 82nd with only 31% of the world average per capita. At present, more than half of China’s provinces and cities suffer from serious water shortages. Experts predict that by 2010, the national water demand will be 700 billion cubic meters, with a water supply capacity of 660 billion cubic meters and a water shortage of 40 billion cubic meters. The total water resources in Jilin Province is 40.425 billion cubic meters, of which 356.57 billion cubic meters of runoff from rivers, 11.318 billion cubic meters of groundwater, 1526 cubic meters of surface water per capita, while the national average per capita is 2700 cubic meters The issue of water resources has become an important factor restricting the national economic development in Jilin Province.
