中国境内河流众多，流域面积在1000平方公里以上者多达1500余条。由于主要河流多发源于青藏高原，从河源到河口落差很大，因此中国的水力资源非常丰富，蕴藏量达6. 8亿千瓦，居世界第一位。长江是中国第一大河，全长6300公里，仅次于非洲的尼罗河和南美洲的亚马逊河，为世界第三大河。

China has a good number of rivers, among which over 1, 500 covers a valley area of over 1，000 square kilometers. Most of them originate on the Qinghai-Tibet Plateau and have high drops from their riverhead to their estuary; therefore, China is abundant in waterpower resources with reserves of 680 million kilowatts, ranking first in the world. With a length of 6, 300 km, the Yangtze River is the longest river in China the third longest in the world, second only to the Nile in Africa and the Amazon in South America. 

其上游穿行于高山深谷之间，蕴藏着丰富的水力资源。长江也是中国东西水上运输的大动脉，天然河道优越，有“黄金水道”之称。长江中下游地区气候温暖湿润、雨量充沛、土地肥沃，是中国重要的农业区。黄河为中国第二大河，全长5464公里。

The upstream section of the Yangtze River flows through mountains and deep valleys, thus having rich waterpower resources. The river, serving as a water artery between the west and east of China, is known as the "gold waterway". Besides, thanks to the warm and humid climate, abundant rainfall and fertile land, the middle and lower reaches of the Yangtze River have become China's important agricultural region. The Huanghe River is the second longest river in China with a total length of 5, 464km. 

黄河流域牧场丰美、农业发达、矿藏富饶，是中国古代文明的发祥地之一。黑龙江是中国北部的大河，全长4350公里，其中有3101公里流经中国境内；珠江为中国南部的大河，全长2214公里。除天然河流外，中国还有一条著名的人工河，那就是贯穿南北的大运河。它始凿于公元前5世纪，北起北京，南抵浙江杭州，沟通海河、黄河、淮河、长江、钱塘江五大水系，全长1801公里，是世界上开凿最早、最长的人工河。

With lush pastures, developed agriculture and rich mineral resources, its valley is one of the birthplaces of the ancient Chinese civilization. The Heilongjiang River, the longest river in northern China, has a total length of 4,350 km, with 3,101 km in the territory of China. The Pearl River, the longest one in southern China, has a total length of 2,214 km. In addition to natural rivers, China has a well-known artificial one——the Grand Canal, which runs from north to south. First constructed in the 5th century BC, it connects Beijing in the north with Hangzhou of Zhejiang in the south, linking the Haihe, the Huanghe, the Huaihe, the Yangtze and the Qiantang rivers. With a total length of 1, 801 km, it is the earliest and the longest canal in the world.
