This book aims to illustrate how climate change had impacted the socio-economic development in the history of China, under the framework of food security. The 10 years resolution sequences indexing the status of social and economic subsystems in China over the past 2000 years are reconstructed. Statistical methods are used to reveal the major characters and main process of the impact of historical climate change on China's social economy. This book serves as a reference both for researchers, graduates, and undergraduates majoring in geography, climatology, history, and other related fields.
