Huang Qianren’s Da Qing Wan Nian Yi Tong Tian Xia Quan Tu（《大清万年一统天下全图》）is a national general map of land sea integration. Its knowledge source of the land part can be traced back to Yan Yong’s Da Qing Yi Tong Tian Xia Quan Tu （《大清一统天下全图》）. Its knowledge source of the maritime part is Wang Riang’s Da Qing Yi Tong Tian Xia Quan Tu（《大清一统天下全图》）. Its base map is closer to the Di Yu Quan Tu （《地舆全图》）. And they have an inherent and successive relationship. There are three variation trends among later versions of “Da Qing Yi Tong” map series. First，there appeared the combining form of Yu Di Quan Tu （《舆地全图》）and astronomical map from the end of Qianlong period to the early of Jiaqing period. Second is the changing map style from the hanging scroll to the screen style during the reign of Jiaqing. Third，the painting Gu Jin Di Yu Quan Tu（《古今地舆全图》）was redrawn as a historical map in the Guangxu period. Among them，Huang Qianren’s Da Qing Wan Nian Yi Tong Tian Xia Quan Tu（《大清万年一统天下全图》）is of great significance.
