关于“胡焕庸线能否突破”的学术争鸣

Hu Huanyong, a famous geographer, discovered a divide of population geography in China in 1935 (hereinafter referred to as the Hu Line), which was an important achievement in the development of the discipline of geography in China, and was widely accredited and cited. In November, 2014, Premier Li Keqiang raised a question about the Hu Line, when he visited the exhibition of sciences of human settlements in the National Museum of China. This question is whether the Hu Line can be broken or not again caused a stir. Hereby we invited some geographers to have academic discussion on this question, aiming to demonstrate their understanding and reflection on the Hu Line from different perspectives. Thus, the scientific value and practical significance of the Hu Line are deepened, and furthermore, the Hu Line can provide reference for the implementation and regional planning of the new-type urbanization in China.
