Prevention of natural disasters in the Winter Olympics area

The Winter Olympics are more susceptible to weather than the Summer Olympics. Only four of the past 23 Winter Olympics have not been postponed or canceled due to weather conditions.

The School of National Safety and Emergency Management of BNU, as the main supporting unit, participated in the special work of the first national comprehensive census of natural disaster risks for the Beijing Winter Olympics. 22 teachers and students of the school participated in the assessment, which lasted for 4 months, forming the Special Assessment Report of the First National Comprehensive Census of Natural Disaster Risks for the Winter Olympics. The report offered the Winter Olympic Organizing Committee the background risk information for relevant regions, and provided data basis and technical support for the formulation and testing of disaster emergency response plans.

The Report has scientifically supported the risk management of the Winter Olympics region. The main authors of the report are Wang Ming, Liu Kai, Zhang Zhengtao and Ni Xiaoyong of the School of National Safety and Emergency Management, Xu Yingjun, Zhang Hua, Wu Jidong and Xu Wei of the Faculty of Geographical Science, and 15 graduate students participated in the writing.

Determination, monitoring and forecasting of snow quality on the Winter Olympic Snow Track

Ice and snow are the soul of Winter Olympic Games, and snowmaking, snow preservation and snow storage are the keys to ensuring ski competitions. Since October 2020, Associate Professor Yin Shuiqing of the Faculty of Geographical Science, together with experts in meteorology, ice and snow management, has led graduate students to form a scientific research team. They undertook the research, development and application of Judgment, Monitoring and Forecasting Technology for Snow Quality on the Winter Olympic Snow Track in the Science and Technology Winter Olympics key special project of the Ministry of Science and Technology (PRC)

In 15 months, the team has completed the research, development and the online application of the first snow quality monitoring-forecasting-judgment integrated system of the snow track in China, referred to as the "Snow Protection System" of the Winter Olympics. On January 27, 2022, the Zhangjiakou Competition Zone, which is supported by the "Snow Protection System", formed the first special report of the Snow Risk Prediction During the Winter Olympic Games in the Zhangjiakou Competition Zone. The system directly provided professional decision-making support for the deployment of the Beijing Winter Olympic Organizing Committee and the management and maintenance of the snow field.

Ecological protection and tracking evaluation of the Beijing Mountain Competition Zone of the Winter Olympics

The ecological protection and restoration for the construction of the Yanqing Competition Zone is the most important component of the Construction Project of the Beijing Winter Olympics. The School of Environment of BNU and other units jointly undertook the Project of Ecological Protection and Tracking Evaluation of Beijing Mountain Competition Zone of the Winter Olympics.

Since 2018, Professors Yi Yujun, Li Chunhui, Li Yingxia and Cui Baoshan of the School of Environment have analyzed and evaluated the ecological environment sensitive areas such as the construction of the venues based on the ecological protection goals. They carried out a survey of the planning and design for the sponge competition area in the Winter Olympic Mountain Competition Zone, and screened out the key technologies for ecological protection and restoration for the construction of the sponge competition area.
