中国是个缺水大国,水资源并不丰富,但用水浪费惊人,供求问题十分突出。这个结论,并非危言耸听。我国水资源总量为2.81亿立方米,在世界上仅次于巴西、前苏联、加拿大、美国和印尼而居第6位。绝对量虽算丰富,但由于人口多,人均水资源占有量却大大低于世界平均水平,仅列世界第88位。而且随着人口的迅速增长,人均水资源每年在递减。从淡水资源看,世界人均占有量为12900立方米,我国仅2695立方米,还不到世界人均占有量的四分之一。
China is a big water-scarcer country, its water resources are not abundant, but the waste of water is staggering. The issue of supply and demand is very prominent. This conclusion is not alarmist. China’s total water resources is 281 million cubic meters, ranking sixth in the world after Brazil, the former Soviet Union, Canada, the United States and Indonesia. Although the absolute amount of abundance, but due to population, per capita water resource share is much lower than the world average, ranking only 88th in the world. And with the rapid population growth, the per capita water resources are declining every year. From freshwater resources, the world’s per capita share of 12900 cubic meters, our country is only 2695 cubic meters, less than the world average of one-fourth.
