按照现行国际标准,人均水资源量1000立方米为人类生存起码需求,人均水资源量2000立方米就处于严重缺水边缘。从这个标准来衡量,我国目前有6个省、区,即宁夏、河北、甘肃、河南、山西、陕西,人均水资源量尚不足500立方米,离起码的生存需求都相差甚远。此外,还有16个省、区人均水资源量低于2000立方米。也就是说,我国至少有一半以上省份处子严重缺水状况。水利专家们的预测结果更让人震惊,到21世纪中叶,我国人口将增至16亿,全国人均水资源比现在还要减少1/4。在北方农牧区,干旱缺水尤为
According to the current international standards, the average water resource per capita of 1,000 cubic meters is the minimum requirement for human survival, and the per capita water resource of 2,000 cubic meters is on the verge of severe water shortage. Measured by this standard, China currently has six provinces and districts, namely Ningxia, Hebei, Gansu, Henan, Shanxi, and Shaanxi. The per capita water resources are still less than 500 cubic meters, which is far from the minimum living needs. In addition, there are 16 provinces, districts, per capita water resources below 2,000 cubic meters. In other words, at least half of the provinces in China are seriously deprived of water. The forecast results of water conservancy experts are even more shocking. By the middle of the 21st century, China’s population will increase to 1.6 billion, and the per capita water resources of the country will also be reduced by 1/4. In northern farming and pastoral areas, drought and water shortage are particularly
