[111-3] Major Rivers / 主要河川, 1996

Rivers have been used for transport, as defensive barriers, as sources of hydropower, and as means of disposing of waste. Rivers also provides the cheapest means of transport. They have been a source of food since pre-history. In addition to being a rich source of fish, rivers supply water for crops. Most major cities are situated on the banks of rivers.

河川被用來運輸，並且也可形成防禦壁壘，提供水電資源，或者被當作廢棄物排放點。河流也是最經濟的運輸管道，並且從史前時代便提供了食物的來源。除了蘊含豐富的水產，河川也被用來共應農業用水。許多大城市都是座落在河岸。
