Geoarchaeology has played an important role in a series of important issues such as the origin of agriculture, climate change and cultural adaptation, the strengthening of land use, and the complexity of society. On the afternoon of November 9, our school specially invited Dr. Huiru Lian from the University of Science and Technology Beijing to give a wonderful academic report to our teachers and students on the topic of "Water and the Development of Early Cities: A Case Study of the Geoarchaeology of Liangzhu Ancient City".
Dr. Huiru Lian graduated from the Department of Archaeology and Anthropology at the University of Cambridge, focusing on the interaction between humans and the environment. Usually the main research method is geoarchaeology, and various geological methods such as soil micromorphology and particle size analysis are used. She mainly studies the formation process of the site, climate and hydrological changes and its impact on ancient human activities, the transformation and management of the landscape surrounding the site by prehistoric humans, and the origin and development of complex societies.
First of all, Dr. Lian Huiru introduced the impact of fluctuations and changes in the water environment around the world on early cities. Studies on civilizations such as Maya civilization, Mesopotamia and Nile River basin have found that there are different paths to civilization. However, there are few studies on the hydrological environment of the early societies in East Asia. Dr. Huiru Lian then introduced the basic situation of Liangzhu Ancient City, the existing problems in current research, and the research methods, sampling and sample preparation methods of geological archaeology. Finally, Dr. Lian Huiru introduced the study of soil micromorphology based on multiple sections in Liangzhu area, and then reconstructed the history of the changes in the hydrological environment of the ancient city of Liangzhu, and further discussed the process and history of Liangzhu people constructing terraces and dredging rivers.
Based on the geo-archaeological research of Liangzhu Ancient City, Dr. Lian Huiru focused on several important change nodes in the development of Liangzhu Ancient City, such as early to late Liangzhu, early to late late, and late late to Qianshan Yang. Research suggests that changes in hydrological conditions have a certain impact on the development of the ancient city of Liangzhu, especially in the dry climate and the construction of the ancient city, transgression events and the disappearance of local settlements, the site selection and eventual demise of the ancient city of Liangzhu, etc.
After the report, Dr. Lian Huiru also gave detailed answers to the questions raised by the teachers and students, and the whole lecture ended with warm applause. The lecture was hosted by Associate Professor Jia Xin of our school. More than 20 people, including teachers, graduate students, and undergraduates from Nanjing Agricultural University, the School of Geographical Sciences, and the School of Social Development of Nanjing Agricultural University, attended this lecture.
