Vasiliev's works on the historical geography of China were mainly published in the 1950s and 1960s of 19, and his research is often the continuation of Beechulin's research on the history of China. For example, in the preface of the book History and Monuments in Eastern Central Asia, he pointed out that Niyabi Chulin had missed the history of the Khitan people and the jurchen and Manchu people he replaced, so he decided to fill this gap and summarize the history of more than 300 years. To this end, he translated Liao History and Jin History as appendices to the book. This book uses a lot of little-known materials of Russian Sinology, which is of great scientific value for studying the history of northern China, especially Mongolian history. Manchu history is one of the focuses of Vasilyev's historical research. Comfort of Mongols in the Early Qing Dynasty, Diary of Military Minister Masha's Northern Expedition, Records of Manchuria, Introduction to Ningguta, etc. It constitutes a series of works of Vasiliev's research and translation of Manchu. Unfortunately, many works were not published and became part of a large number of manuscripts he left to future generations.
Vasiliev believes that geography and history are inseparable subjects, so it is necessary to explore history when investigating various geographical phenomena. On the contrary, when discussing historical issues, we should give consideration to geography. Teaching needs are one of the motivations of Vasilyev's geographical research. In his Selected Works of China, he collected monographs on the history and geography of China and translations of ancient books in China. In addition, he also wrote The Geographical Survey of China and A Review of China's Political Geography as supplements to the first volume of Selected Works of China published between 1867 and 1868. The book "A Survey of Geography of China" fully shows Vasilyev's attainments in the geographical research of China. It not only outlines the geography of China, but also includes travel notes. The content and form are detailed and vivid, and it has become a model of geography textbooks in China. Although Data of Manchu in Yuan and Ming Dynasties is a historical research work, it mainly investigates the origin of Manchu, but it also contains a lot of precious geographical data, enumerates ancient towns and describes mountains and rivers.
Another of his famous geographical works is Manchu Tongzhi published in 1857, and he published a translation of Ninggutalue as an appendix to the book. This book introduces the geographical and administrative divisions of China, describes the local cities and residents, and discusses land and water transportation in particular. 1852 Published "Central Asia and China's Main Mountains" in the Journal of the Ministry of Education. Although the space is not large, the content is substantial. In addition, Vasiliev also wrote some small articles that belong to the category of geographical research in China. For example, memories of Beijing, suggestions for travelers who choose to go to China, alfalfa and autumn in Yili. Vasiliev's historical and geographical works did not arouse great repercussions during his lifetime, and it was not until the Soviet period that they were sorted out and studied by several sinologists who studied the history of Russian Sinology.
1900 On April 27th, Vasiliev died at the age of 82. Vasiliev's manuscript is twice as much as his published works. These manuscripts became silent testimony of Russian China studies.
