　　The study of Bet365 app download presents multi-dimensional value

Bet365 app download are an important part of our country’s historical documents，Systematic research on Bet365 app download，Not only is it helpful to promote the genealogical identification methods and theoretical construction of Bet365 app download in my country，Enriching the history of Chinese cartography、Research on the history of geography and related disciplines，Also effectively protect China’s excellent traditional culture、Inheritance and development work are of great significance。

Maps not only visually express geographical space, but also contain many elements of time。Proposed by Wang Qianjin, Director of the Cartographic Research Institute of the National Museum of China，Analysis of the concept of time in Bet365 app download、Time elements such as time types and time systems，Not only can we study the physical geography of Bet365 app download、Specific contents such as human geography and geographical concepts，Measurement of Bet365 app download、Draw、Technical issues such as publication and dissemination have important practical significance，And it has important theoretical significance for understanding the geographical cognition and expression of ancient people。

Li Xiaocong, professor of the Department of History at Peking University, made some suggestions on the current research on Bet365 app download。Looking for text books or files related to map descriptions，Especially the various thematic maps drawn during the Ming and Qing Dynasties，Restore the relationship between maps and text as much as possible。Time that must be displayed on the map、Location、Character、Deeds to be tested，This is the basis for ancient map research。Strengthen the explanation of ancient map drawing methods，That is, the exploration of the technical aspects of surveying and mapping。At the same time，We also need to rely on the history of thought、Art History、Theoretical methods of image history，Interpretation of Bet365 app download。Especially the order of studying these Bet365 app download cannot be put the cart before the horse。

The ancient map of the Yellow River is of great value in the study of Bet365 app download。The Yellow River is the core object of river governance and governance by central governments in past dynasties，Therefore, it has become an important theme element in historical documents and traditional map depictions。Currently，The National Library of China and dozens of other institutions at home and abroad hold ancient Yellow River maps，More than a thousand published，Provides literature for our study of the development, governance and ecological protection of the Yellow River Basin。Introduced by Professor Hua Linfu from the Institute of Qing History, Renmin University of China，The Library of the Institute of Geographic Sciences and Natural Resources, Chinese Academy of Sciences has a well-preserved long scroll-style ancient map of the Yellow River，There is no other version of this picture yet。The author of this map drew the lower reaches of the Yellow River in great detail，This can be used to restore the river management of the lower reaches of the Yellow River in the early Qing Dynasty and the "Yellow"、Huai、The relationship between the three rivers of Yun"。

　　Give “digital wings” to the study of Bet365 app download

Digitization research on Bet365 app download is one of the important directions in ancient map research，It is also a hot topic discussed by scholars at this conference。Expressions from participating scholars，The current technological trends in ancient map digitization research and digital humanities research deserve attention。At the same time，The application method of this technology still needs to be summarized and reflected on。

Digital research on Bet365 app download can effectively verify the way ancient Chinese people drew maps。In recent years，Academic circles are studying Bet365 app download，Most people agree that ancient Chinese used the relative positional relationship between features as the basis for drawing maps。But，This view has always lacked practical evidence and reliable testing methods。Sun Jingguo, director of the Historical Geography Research Office of the Institute of Ancient History, Chinese Academy of Social Sciences, and other scholars have used technical means such as GIS and Python，Research and discovery of 8 types of 28 Ming Dynasty Xuanfu Town maps，The relative positions of the castles on the 8 Ming Dynasty Xuanfu Town maps are very consistent with the actual situation，It shows that the central government and the border town government offices in the Ming Dynasty were very familiar with the geographical situation of the castle。Proposed by Sun Jingguo，In terms of presentation，The castle system is related to its relative position to each other，Reflects the method of using the relative position of features on ancient Chinese maps to build a coordinate system。A small number of inconsistent ones，Mainly caused by geographical factors and layout factors。

Currently，Academic discussions on transportation routes in Bet365 app download mostly focus on the selection of transportation nodes，There are few studies on the specific quantification and analysis of traffic routes。Jiang Wan, a young scholar from the National Museum of China thinks，Using the shortest path analysis module in ArcGIS software，The relationship function combining human walking speed and slope，A line model of ancient transportation routes can be constructed based on the data of the digital elevation model，Quantitative marking of ancient transportation routes。Jiang Wan said，Use this method，Also refer to historical documents，Overlay travel time analysis，Can obtain the calculation relationship function between ancient traffic routes and time loss。This method helps to understand the history of culture、Politics、Military exchange routes provide more detailed quantitative data reference。

The meeting was organized by the National Museum Research Institute of China、Sponsored by the Institute of Qing History and the Historical Geography Research Center Bet365 app download School of History, Renmin University of China。
