In recent years, academic circles have heatedly discussed the issue of “South-to-North Water Diversion ”. This article attempts to analyze this issue from the perspective of economic geography. First, the North China Plain (refers to the Yellow River north, the same below) and the Yellow River water resources profiles: North China Plain densely populated, with 140 million people, is one of China’s major agricultural areas, and the famous Beijing-Tianjin Tang Industrial Zone, so the industry and agriculture The production of water and domestic water demand is great. From the perspective of the natural division of the entire world and our country, the water resources in the humid area (with an annual rainfall of 800 mm and a variable rate of ≤ 20%) can generally meet the economic development in the area
