山西是我国目前煤炭探明储量最多的省区,素有“煤海”之美称,是我国重点建设的煤炭、重化工基地。但同时山西又是我国水资源相当短缺的省区。全省人均水资源占有量仅466m~3,约相当于全国人均水平的17％,世界人均水平的4％;因全年降水多集中于七八月份,全年旱涝明显,水资源利用率低,每年缺水量约9×10~8～16×10~8m~3,水资源严重短缺与 Shanxi is the province with the most proven coal reserves in China. It is known as the “coal sea” and is the key coal and heavy chemical base in China. However, at the same time, Shanxi is a province in which China’s water resources are relatively short. The per capita water resources in the province is only 466m~3, which is equivalent to 17% of the national average level, and 4% of the world’s per capita level. Because the annual rainfall is concentrated in July and August, the drought and flood are significant throughout the year. Low, the annual water shortage is about 9×10~8~16×10~8m~3, and there is a serious shortage of water resources.
