On April 12th solstice 15th, 2016, The summary briefing about the major national scientific research project——“The Research of East-central China Extreme Climate Events and Origin of Agricultural Development and Human Adaptation since The Last Deglaciation Period”(Item Number:2015CB953800)which professor Zheng Hongbo bore the chief scientist was held smoothly in International Exchange Center of Nanjing Normal University. This project aimed at the national major scientific research project’s support direction in 2015, that is “Research on the characteristics, mechanisms, trends and adaptation of extreme climate change ”in “global change research”. This research chose the most typical region of climate change as well as agriculture origin and development which located in eastern China, reconstructed the process of climate change since the last deglaciation periods, clarified the origin, development of agriculture and the temporal and spatial patterns of spread, revealed the patterns and strategies for human adapting to climate change. This research not only provided history lessons and scientific basis for responding to future climate change, but also made theoretical innovation in the basic major international issues of   cognizing the relationship of agricultural origin and climate change.

The project’s chaired unit is Nanjing Normal University, participating units include Institute of Geology and Geophysics (CAS), University of Science and Technology of China (USTC), Institute of Vertebrate Paleontology and Paleoanthropology, Institute of Geographic Sciences and Natural Resources Research (CAS), Institute of Archaeology of Zhejiang province. Project tracking expert Wang Sumin, expert group members academician Guo Zhengtang, researcher Zhou Jie, professor Cheng Hai, researcher Yuan Jing, researcher Shen Ji, professor Lu Huayu, professor Liu Jian, professor Zheng Hongbo and more than 70 main members fromeight units of the project team at home and abroad took part in this meeting. In addition, Project tracking expert academician Ding Zhongli and expert academician Chen Fahu did not attend the meeting for some reasons.

Entrusted by ministry of science and technology, professor Wang Sumin  wished this meeting wound be held successfully,and hoped the project could be the wonderful bright spot in science frontiers of china's agricultural origin and history of civilization, meanwhile being fully prepared to welcome the mid-term assessment report which will be held in end of August. Professor Zheng Hongbo who held the post of the project’s chief scientist introduced the project progress first, and made a report from the aspects of project management, research progress, research results , future plans and so on. The project was divided into four topics, researcher Lv Houyuan, professor Zhang Juzhong, researcher Li Xiaoqiang and professor Zheng Hongbo did the report respectively on issues of one, two, three, four’s work progress and research results, and each issue showed 3 or 4 highlight achievement.

This project’s bright points were mainly embodied in the following aspects: First, in term of crop indicators, the research build a distinguishing methods between the wild and cultivated rice thereby providing a new means in the research of rice origin and domestication. Second, in term of agricultural origin, the origin of rice cultivation could be traced back to ten thousand years ago; Plants of the genus tares had ever been collected and processed by human ten thousand years ago. Third, in term of ancient climate quantitative reconstruction, the research  rebuild the change of holocene precipitation in the guanzhong basin on account of millet carbon isotope quantitative. Fourth, in term of paleoclimate simulation, the topic of Global and East Asian monsoon in last glacial maximum (LGM)’s multimodal set simulation methods had been explored and had gotten progress. Fifth, in term of the relationship between environmental changes and the evolution of agricultural origin, the project contoributed to gaining systematic understanding about Hang-Jia-Hu and Ning-Shao region’s sea-level change, land formation, extreme climate and environmental events and the influences of Neolithic settlement resulted from these causes in holocene.

After the end of the seminar, participants conducted for a three-day’s project work investigation (From 13th-15th,Apr.) , the project experts and the major participating members visited Hemudu Ruins Museum, Tianluoshan Ruins Museum, Liangzhu Ancient City Ruins, Liangzhu Dam Site, Kuahuqiao Site Museum and related natural sedimentary section, then got a deeper understanding of the relationship among the Neolithic cultural sites, environment changes and extreme climate and environmental events, which won the highly recognition and evaluation from experts.
