我国年平均径流量26.380亿立米,居世界第六位,少于巴西、苏联、加拿大、美国和印尼,但人均占有径流仅约2,700立术,远低于世界人平均值1万立米,占世界85位。因此,我国是人均占有径流量较少的国家。我国1978年总用水量4,767亿立米,其中农业用水4,195亿立米,工业用水523亿 China’s annual average runoff is 2,638 billion cubic meters, ranking sixth in the world, less than that of Brazil, the Soviet Union, Canada, the United States and Indonesia. However, the average runoff per capita is only about 2,700 liters, well below the world average of 10,000 cubic meters 85 places. Therefore, our country is a country with less runoff per capita. In 1978, China’s total water consumption was 477.6 billion cubic meters, of which agricultural water was 4,195 billion cubic meters and industrial water was 52.3 billion
