我国城市缺水研究

选取了全国365个城市作为研究对象,进行城市需水、供水和缺水分析,并按照六大分区统计汇总。分析结果表明:按1999年水平年研究城市总需水量为663.4亿m3,总供水量为599.9亿m3,缺水量达63.5亿m3,如果除去超采的32.2亿m3地下水,缺水量达到95.7亿m3。进一步分析认为全国667座城市缺水达到105亿m3。分析制定了缺水标准,据此,研究城市中有275座城市缺水,其中重度缺水城市达93座,并进行了缺水城市的缺水性质、缺水分布和缺水影响的分析。

Study on city water shortage of China

The paper chooses 365 cities to study the current situation of water demand,water supply and water shortage.The result are summarised in six sub-areas.The study shows water demand of the all study cities is 66.34 billion cubic meters,the water supply is 59.99 billion cubic meters,and the water shortage is 6.35 billion cubic meters.If ground water is not being over used,the water shortage is still about 9.57 billion cubic meters.If we extend those datum further to all Chinese cities,the shortage of water supply is 10.5 billion cubic meters.According to the water shortage standard established in the paper,275 cities are lake water,of which 93 severe water shortage ones.The paper analyzes the character,distribution and influence of water shortage.
