长江与黄河同是中华民族的发祥地。长江流域大部分处于亚热带,气候温和、雨量充沛,生态环境优越,森林植被茂密,生物、水能和矿产资源丰富,所以从唐代起经济发展就超过了黄河流域,此后一直成为中国的经济中心。今天,长江流域的战略地位就更为重要。长江流域的土地仅占全国土地面积18.8％,而人口占全国人口的35％;耕地面积占全国耕地的25％,而粮食产量占全国粮食总产量的40％。水稻产量占全国的56％,淡水鱼产量占全国的48％,是蚕丝、茶叶、桐油等传
The Yangtze River and the Yellow River are the birthplaces of the Chinese nation. Most of the Yangtze River valley is in the subtropical zone with mild climate, abundant rainfall, superior ecological environment, dense forest vegetation, abundant biological, hydropower and mineral resources. Therefore, its economic development surpassed that of the Yellow River since the Tang Dynasty and has since become the economic center of China. Today, the strategic position of the Yangtze River Basin is even more important. The land in the Yangtze River basin accounts for only 18.8% of China’s total land area, while its population accounts for 35% of the country’s population. Its arable land accounts for 25% of the country’s cultivated land, while its grain output accounts for 40% of the country’s total grain output. Rice production accounts for 56% of the country, freshwater fish production accounts for 48% of the country, is silk, tea, tung oil and other pass
