The Qinghai-Tibet Plateau (QTP) is a key region with diverse and frequent natural disasters in China. Earthquakes, landslides, mud-rock flows, glacial lake outburst, and snow disasters are widely developed in the region, which have a wide distribution of disasters and huge damage and impact, and have become an important constraint to the sustainable and healthy development of the plateau’s economy and society. The risk levels of natural disasters on the QTP have obvious spatial heterogeneity. The high-risk areas for earthquakes, landslides, mudslides, and glacial lake outbursts generally located in a large area on the southern and eastern edge of the QTP as a whole, which is also the area where multiple disasters occur frequently. Many road networks and pipe networks are located in this area, which has great potential hazards. The QTP has complex topography and landforms, strong spatial heterogeneity of climate change, developed cryosphere, extensive transportation and other infrastructures, and poor economic conditions. These factors have formed the main hazard factors and disaster-generating environment for the development of multi-natural disasters. The QTP is affected by multiple disaster-causing factors, and the multi-disaster-bearing bodies overlap. It is urgent to strengthen the comprehensive management and control of multi-natural disaster risks. The dominant idea of comprehensive risk control is that decision makers use the research results of multiple disasters mechanisms to prevent, mitigate or avoid comprehensive risks of multi-natural disasters through engineering and non-engineering measures with the help of the concept of joint prevention and control of various departments. Specific comprehensive risk management and control strategies include real-time monitoring/observation, information sharing, multi-ministerial consultation, mass observation and mass preparedness, education and training of disaster prevention, disaster insurance, and pre-disaster planning.
