June 10-11，Sponsored by the Historical Geography Professional Committee of the Chinese Geographical Society，School of History, Capital Normal University、School of Resources, Environment and Tourism、The "8th Historical Geographic Information System (HGIS) Academic Salon" jointly organized by the bet365 offers Center and others was held in Beijing。From 59 universities at home and abroad、More than 90 expert representatives from scientific research institutions and enterprises and institutions attended this salon，In-depth discussion on the new development of historical geographical informatization and digital humanities。

　　First，The bet365 offers HGIS database and data tools is the highlight of this salon。Using GIS software for bet365 offers，Greatly improves the research accuracy of historical geographical issues，This is a sign that the discipline of historical geography has entered the information age in recent years。China’s historical geographical information development has been more than 20 years ago，From the initial analysis with the help of geographical information system software to the comprehensive historical geographical information development in the new era，The development of disciplines is becoming more and more mature，The characteristics of one’s own disciplines are becoming more and more prominent。Professor Zhang Ping of the School of History of Capital Normal University comprehensively analyzed the conceptual development of historical geography information、Connotation and contemporary value，Considering that historical geography changes from traditional evolutionary geography to historical geography，Back to the information age of historical geography，It is the transformation and progress of the entire discipline，This is also the important responsibility and mission entrusted to us by the times。And around the development of historical geographical information，HGIS database construction is becoming more and more mature，More and more types，Including the construction of Chinese historical death and life span database、Organization and service platform construction of Grand Canal spatiotemporal data、Development of Malaysian Historical Geographic Information System、Telegraph Historical Geographic Information System、The construction plan of the red cultural resources database in the old revolutionary areas has been included in the relevant discussions。Professor Fan Rushen of the bet365 offers Center of Fudan University also described in the conference report the specific situation of the construction of the survey data database of the three major industrial and commercial intelligence agencies in Osaka, Japan, a major project of the National Social Science Fund that he undertook。About image geographic information database，Zhang Tao, a lecturer at the School of Urban and Environmental Sciences of Central China Normal University, introduced the architectural issues of China’s historical plague image database。

Although the first step in the construction of bet365 offers geographical information is the construction of relevant databases，But due to tool development and the use of artificial intelligence，Can greatly improve work efficiency，bet365 offers geographers have also shown great initiative in this field in recent years。On the one hand，Use existing information technology products to serve this discipline，For example, Xu Juan, a doctoral candidate at the School of History and Archives of Yunnan University, introduced the use of corpus technology in the study of the Yellow River in the Qing Dynasty。On the other hand，Che Qun, associate researcher at the Department of History at Shanghai Jiao Tong University, reported on the local history research tool LoGaRT developed by the school in cooperation with the Max Planck Institute in Germany，Zhang Guangwei, a lecturer at the School of History and Culture of Shaanxi Normal University, tried to combine GeoAI with the bet365 offers geographical information system to identify ancient maps，The development of these new technology products also provides great convenience for the development of bet365 offers geographical information。

　　Second, the bet365 offers on digitization of ancient maps is a hot topic of discussion.Geographic information technology provides a broader space and greater possibilities for the study of ancient maps。Use the map registration function in Arcgis software，Digital extraction of ancient maps，Translated into digital map，Can make map history research more precise。Professor Wang Qianjin bet365 offers Institute of Natural Science History, Chinese Academy of Sciences first introduced the basic principles and methods of ancient map identification，Provides the most basic cognitive norms for map research。A map with no actual measurement basis for ancient China，Scholars will place name information、Combination of archaeological remains and basic data on the map，Respectively on the "Pictures bet365 offers Traces of Yu" bet365 offers Song Dynasty、Nine-sided map of Ming Dynasty、Wuding River water system map since the Qing Dynasty、The drawing accuracy bet365 offers Qing Dynasty's "Border Map bet365 offers Four Provinces North bet365 offers Han River" and Yale's "Ancient Chinese Navigation Chart" was examined，Positioning through digitalization，Discuss how ancient people drew maps，Whether ancient maps have spatial indicativeness and practical application value。Luo Yaoze, a senior engineer at the China Natural Resources Aviation Geophysical Exploration and Remote Sensing Center, introduced his research on the digital restoration of Matteo Ricci’s east and west hemisphere maps，And its projection type、Analysis on surveying and mapping technology and geographical cognition。

A more in-depth study on the digitization of maps with measured properties during the Republic of China，The delegates first started with the method of map digitization，Shows the cities on the measured map bet365 offers Republic of China、Market、River system、Extraction and spatial analysis methods of political region boundaries and other elements。The extraction of map data also facilitates further problem research，Therefore，Research results in this direction have been fruitful in recent years。Li Zhijun, a professor at the School of History and Cultural Heritage of Xiamen University, uses map data from the Ming and Qing Dynasties，Combined files、Fang Zhi、Research on coastal defense anthology and other literature，clarified the formation process bet365 offers Nan'ao Island coastal defense zone boundary in the Ming and Qing Dynasties、Spatial distribution characteristics and their relationship with administrative division boundaries。Jiang Weitao, associate researcher at the Guangdong Academy of Social Sciences, extracted the number and area of ​​commercial settlements from the one hundred thousandth topographic map bet365 offers Republic of China，Calculation of average market density by county、Market scope and market radius，And use GIS software to conduct visual analysis of market density by county，Also use the Thiessen polygon analysis method in GIS software，Calculate the market scope and radius of each commercial settlement，Thus conducted an in-depth study bet365 offers grassroots market network in Jiangnan and Lingnan in modern times。In addition, the boundaries of political districts reflected in old maps、Transportation routes and other issues，Scholars also have many discussions。Huo Renlong, associate researcher at the School of International Relations of Sichuan University, also based on the British surveying and mapping activities in southeastern Tibet in the 18th and 19th centuries and related map content，Analyzed the development and evolution of people’s geographical understanding of this region during this period。

　　Third，Using geographical information technology to study natural and human geography issues in bet365 offers periods is still the most discussed topic in the salon，This is also the focus of discussion。No matter from the invention of geographic information system technology or the application of artificial intelligence，The ultimate goal is to conduct research on bet365 offers, natural and human geography issues，Solve the fundamental problems of bet365 offers geography。In the study of bet365 offers and physical geography，Research on land use/cover change (LUCC) in bet365 offers periods is still the focus，The focus is on the changes in surface water bodies during the urbanization process of Shanghai、Compilation of bet365 offers reclamation data on tidal flats along the Suzhou-Shanghai coast and reconstruction of bet365 offers cultivated land in South Asia、Reconstruction of forest and grassland cover patterns in the continental United States，Reflects the transformation of research perspective from domestic to international。In the study of bet365 offers geomorphology and hydrology，Du Longjiang, senior engineer of China Institute of Water Resources and Hydropower, under the framework of digital twin watershed technology，Using multidisciplinary intersection、New method of multi-source data fusion，Quantified the changes in the water system of the Haihe Plain and the urban evolution process、Modeling Research，Discovered the emergent relationship between urban distribution and river geomorphological environment、Spatial coupling relationship between dynamic adjustment and adaptive features，Revealing the urban layout of the river basin since 2000、The adaptation and reconstruction mechanism of water conservancy projects to the river geomorphological environment。Research by Wen Penghui, a lecturer at the School of History and Culture of Northwest Normal University, on the environmental changes in the ancient city of Sancha River in the upper reaches of the Wuding River since the Yuan Dynasty，is a typical case of applying archaeological methods to the study of bet365 offers landforms and hydrology。Also，Research on bet365 offers climate and human society is also valued by participating scholars。Xiao Lingbo, associate professor at the Institute of Qing History at Renmin University of China, conducted a statistical analysis on the impact of floods and droughts in North China on the implementation of the Northeast immigration policy in the early and mid-Qing Dynasties，Think that the Qing Dynasty lasted more than two hundred years，The Northeast immigration policy is constantly adjusted，Tight and loose，Floods and droughts have a great impact on immigration policy。Shi Guoning, a lecturer in the Geography Department of Handan University, analyzed the relationship between the epidemic of animal diseases and climate change in the Qing Dynasty，The above research enriches our understanding of the interaction between climate change and human development。

​​In history and human geography，Because geographic information systems can more intuitively and clearly present the spatial distribution patterns and changing trends of various humanistic elements，Visual analysis becomes mainstream。Research on bet365 offers cities includes the bet365 offers geographical information mining of Miyun Mancheng in the Qing Dynasty by Zhu Yongjie, a professor at the Institute of Beijing Studies at Beijing Union University、Associate Professor Zhao Huanxi of the School of Resources, Environment and Tourism, Capital Normal University, research on the bet365 offers geography of Beijing’s residential space and spatial behavior、Wang Changsong, a researcher at the School of Urban and Environmental Studies at Peking University, analyzed the spatial structure characteristics and influencing factors of the Beijing guild hall during the Republic of China。Also，The time and space changes of the county governance relocation in Anhui’s Kuomintang-controlled areas during the Anti-Japanese War、Spatial distribution of troops and changes in defense strategies in Sichuan during the early and middle stages of the Song-Mongolian War、Recovery of the transportation system in Wei, Jin, Southern and Northern Dynasties、Research on traffic changes and local politics on Guilinfuyi Road in Guangxi during the Ming Dynasty、The evolution of time and space adjusted by the Xinjiang Post Office in modern times、Research on place names of ethnic minorities in Guangxi and Yunnan、The geographical process of the teachings of the Linji Sangha from the 10th to the 12th centuries、History and politics such as spatial distribution characteristics and analysis of the causes of Tibetan Buddhist temples in Kham Tibetan area、Military、Transportation、Problems in multiple directions of cultural geography，All researched and discussed in this salon report。Among them，Kyoto University doctoral candidate Li Wenlong used reconstructed ancient Chinese transportation data、Population data、Social network data, etc.，Building a gravity model and a bet365 offers transportation convenience model，Convenience of transportation in ancient China、General social tolerance for long distance travel、The self-reinforcing effect of social networks and other important issues in the bet365 offers development of relationships were discussed。Li Zehao, a doctoral candidate at University College London, based on the known location of the city site during the Qin and Han Dynasties，Establishing a spatial interaction model，Predicted the location and northern extension of the northern section of Qinzhi Road，It corresponds well with the literature research results，The model shows the potential to explore other transportation routes in the region during the Qin and Han Dynasties。Professor An Chengbang of the School of Resources and Environment of Lanzhou University has passed a large number of field surveys，Combined Archeology、History、Chronological system and the politics of the development of various bet365 offers dynasties in southern Xinjiang、Economic and other characteristics，Using kernel density analysis in GIS、aggregation analysis、Overlay analysis and other methods，An in-depth analysis of the spatial distribution characteristics of human activity sites in southern Xinjiang since the Bronze Age，It is a comprehensive study。Hu Heng, associate professor at the Institute of Qing History at Renmin University of China, also shared his new exploration into the construction of digital humanities infrastructure and the study of the history of bureaucratic politics in the Qing Dynasty。Also，Liu Lei, a master’s student at the School of Architecture, Harbin Institute of Technology (Shenzhen)、Yu Baoyuan established two databases on the life trajectories of poets in the Tang Dynasty and the geographical images of frontier fortress poems in the Tang Dynasty，Use the overall coupling situation model，Preliminarily reveals the relationship and mechanism between the real space of frontier poems and the image space in literature，This is also a main direction of current digital humanities research。

The Historical Geographic Information System (HGIS) Academic Salon sponsored by the Historical Geography Professional Committee of the Chinese Geographical Society has been successfully held for eight sessions so far，It has established a good communication platform to promote the construction of historical geographical information systems and new explorations in the field of digital humanities research。Director of the Historical Geography Professional Committee of the Chinese Geographical Society、Zhang Weiran, professor of the bet365 offers Center of Fudan University, reviewed the holding of the eight HGIS salons，Think that the HGIS salon has twenty or thirty people from the first session in 2015，Today’s conference with more than 100 people，has become a position reflecting the forefront of bet365 offers。At the closing ceremony of the conference，Zhang Ping made a concluding speech。She believes that there are two most outstanding features of this conference: First, the conference papers cover a very wide range of contents，This also reflects that HGIS’s tentacles have penetrated into all directions of bet365 offers。Secondly, topics such as the peak algorithm emerged in conference reports、SegNet model、LoGaRT、GeoAI、Digital twins and other new research methods，All reflect the important driving force of information technology to the new development of bet365 offers。Historical geography informatization moves toward multidisciplinary intersection、Moving towards integration，The development of disciplines is becoming more and more diverse，It also allows us to see the huge potential for the future development of this subject，I feel deeply that the future is promising。
