From May 2 to 4, 2019, the annual meeting of the Chinese Geographic Society (East China) in 2019 was held in Ningbo, sponsored by the Chinese Geographic Society. With the theme of “Geography and Green Development”, the conference invited the academicians of Xiajun College of Wuhan University, Professor Jiang Guojun of Zhejiang Normal University, Professor Lu Huayu of Nanjing University, Professor Yang Xiaoping of Zhejiang University, Professor Liu Min of East China Normal University, Professor Yuan Linwang of Nanjing Normal University, Professor Chen Xing of Institute of Geographic Science and Resources of Chinese Academy of Sciences and other famous experts and scholars from China to Meeting.The conference attracted more than 1000 delegates from universities, scientific research institutes and relevant departments of geography, exchanged frontier theories and research hotspots in the field of geography, shared new trends in academic research and major needs of national macro-decision-making, and provided practical basis for the green development of geography.

Professor Yuan Linwang and his doctoral students Gao Hong, Zhou Xinxin and several graduate students jointly attended the meeting. On May 2, Professor Yuan Linwang, as an invited guest, gave a report entitled “The Theory and Method of Scene GIS Construction”, introducing the theoretical research of Scene GIS from the aspects of the subject ownership of Geographic Information Science and the demand of social services, and planning and thinking about the future of Scene GIS.

Following the invitation, 12 parallel conference sessions with different themes were set up. On the afternoon of May 3, Dr. Zhou Xinxin presented a report on “the Accessibility of Comprehensive Urban Service Facilities based on Multiple Modes of Transportation” at the Theme Conference of “High-quality Integration and Urban Agglomeration Development in the Yangtze River Delta”. On the morning of May 4, Dr. Gao Hong gave a report on “Pulse Response of Vehicle Flow to Air Pollution on Ring-shaped Expressway in Coastal Cities” at the Theme Conference of “Resources, Environment and Sustainable Development in the Eastern Coastal Region”. Both reports were widely concerned and discussed by experts, scholars and students.

2019年5月2日-4日，由中国地理学会主办的“2019年中国地理学会（华东地区）学术年会”在宁波召开。大会以“地理学与绿色发展”为主题，邀请了武汉大学夏军院士、浙江师范大学蒋国俊教授、南京大学鹿化煜教授、浙江大学杨小平教授、华东师范大学刘敏教授，南京师范大学袁林旺教授、中国科学院地理科学与资源研究所陈明星研究员等国内著名专家学者参加会议。会议吸引了来自国内高校、科研院所、地理学相关行业部门的1000多名代表，交流了地理学领域的前沿理论与研究热点，分享了学术研究的新动向与国家宏观决策的重大需求，为地理学绿色发展提出了切实可行的依据。

袁林旺教授及其博士生高鸿、周鑫鑫和多名研究生共同参加了此次会议。5月2日，在特邀报告环节，袁林旺教授作为特邀嘉宾作了题为“场景GIS构建的理论与方法”的报告，从地理信息科学学科归属、社会服务需求等方面介绍了场景GIS的理论研究，并对场景GIS的未来作了规划与畅想。

特邀报告之后，设置了12个不同主题的平行会议分会场。5月3日下午，周鑫鑫博士在“长三角高质量一体化与城市群发展”主题分会场中作了“基于多种交通方式的城市综合服务设施可达性研究”报告；5月4日上午，高鸿博士在“东部沿海资源环境与可持续发展”主题分会场中作了“沿海城市环状布局高速公路车流量对空气污染的脉冲响应”报告，这两个报告都受到与会专家学者、学生的广泛关注与热烈讨论。

June 23-24, 2018, the symposium “Remote Sensing of Resources and Environment and Geospatial Information Applications”, hosted by the School of Tourism and Geography, the Key Laboratory of Resource and Environment Remote Sensing of Yunnan Province, and the Geospatial Information Engineering Technology Research Center of Yunnan Province, was held at Yunnan Normal University. The conference focused on the theme of “Development of Remote Sensing Technology in the New Age Resource Environment”.

Professor Linwang Yuan was invited to attend the symposium and gave a report “Geometry Algebra and GIS: Mapping and Construction”, which analyzed the relationship between different disciplines and GIS from the point of view of mathematics and physics, and analyzed the application in GIS software.

June 4-5, 2018, at the invitation of Professor Lin Li, Department of Geographic Information and Map Science, Professor Linwang, Yuan went to the School of Resources and Environmental Sciences of Wuhan University for academic exchanges and made an academic report entitled “Geometry Algebra and GIS: Mapping and Construction”.

In his report, Professor Yuan introduced the basic methods and characteristics of the application of geometric algebra to geospatial data modeling and spatial analysis from the perspective of geospatial features, and particularly introduced his research achievements and progress in this direction in recent years. Show the application prospect of geometric algebra in multidimensional modeling and analysis of geospatial data.

September 21, 2017, Professor Linwang, Yuan and Professor Tao, Wang and others went to the Northwest A&F University to have discussions with the leading group of the Institute of Resources and Environment and some teachers. Professor Yuan and Professor Jialong, Lv, dean of the School of Resources and Environment, respectively, introduced in detail the history of the development of the college, the teaching staff, the professional setup, the discipline construction, scientific research, and so on. And they also discussed and communicated the ideas of talent training, discipline construction and scientific research about the two colleges.

May 13, 2017, Jiangsu colleges and universities Geography Graduate Forum held at Hehai University，There are about 300 experts, scholars and representatives of graduate students. from Nanjing normal University, Hehai University, Nanjing Institute of Geography and Lakes of Chinese Academy of Sciences, etc. attended the forum.

The purpose of the Forum is to provide a wide range and multi-field academic exchange platform for graduate students in order to broaden academic horizons, activate scientific research thinking, stimulate research enthusiasm, and improve innovation ability. To realize the organic coordination and benign interaction among the graduate students in various colleges and universities. Professor  Linwang, Yuan gave a presentation on the topic of Mathematics and Geography: Mapping and Reconstruction.
