富饶的长江流域长江是我国最大的一条河流。它的流域面积约近200万方公里,占全国总面积的五分之一;聚居着人口25000万,占全国人口的五分之二。长江水量很大,每年入海水量达10,000亿公方,等于25条黄河的水量,比世界最长的密西西比河还大一半。流域内有十多条主要支流,蕴藏着丰富的水力资源,总蕴藏量达22000万(?),约占全国的40%,超过美、英、法等国水力资源的总和。可开发利用的水力资源在14000万(?)以上;如果全部开发,以每(?)相当14个成年人的力量计算,就等于20亿人的力量。
The Yangtze River, the fertile Yangtze River, is the largest river in China. Its basin area is about 2 million square kilometers, accounting for one fifth of the total area of the country. It has a population of 250 million, accounting for two-fifths of the national population. The Yangtze River has a large volume of water, with an annual influx of 10,000 billion square kilometers of water, equal to 25 of the Yellow River’s water, half the size of the Mississippi River, the longest in the world. There are more than ten major tributaries in the basin, which are rich in hydropower resources with total reserves of 220 million (?), Accounting for about 40% of the national total, exceeding the sum of hydropower resources in the United States, Britain and France. More than 140 million hydropower resources can be exploited and utilized; if fully exploited, the power of 14 adults per (?) Equals the strength of 2 billion people.
