Gansu, China, September 25, according to Lanzhou report (sun Li), since this year, major disasters have occurred frequently in our province, with more than 5 million people in 81 counties (cities, districts) affected, causing major economic losses. The Provincial Department of science and technology actively organized the relevant scientific and technological experts of our city to actively go to the disaster areas, and cooperated with the competent departments of disaster prevention and mitigation to do a good job in various emergency response work of disaster prevention, mitigation and disaster relief

as the competent department of science and technology development planning and science and technology project management, the science and technology department is relatively familiar with the situation of experts in various fields and professional strengths. To this end, the provincial and municipal science and technology departments pay attention to playing a good role as a bridge, and coordinate and contact experts in relevant fields of our city in time to participate in the emergency disposal of the disaster after the disaster

on July 12, after the "7.12" large-scale landslide geological disaster occurred in jiangdingya, Nanyu Township, Zhouqu County, Professor Meng Xingmin, head of the flood control and rescue expert group of the Provincial Department of science and technology and professor of Lanzhou University, as a member of the front headquarters and expert group of the Department of land and resources, participated in the rescue and disaster relief work of jiangdingya large-scale landslide geological disaster in Nanyu Township, Zhouqu County, and provided decision-making basis for the disaster relief headquarters and the provincial Party committee and government, It provides technical support for opening up a "second channel" for the diversion and discharge of Bailong River

on August 9, due to continuous heavy rainfall, landslides occurred from Dashaping entrance of the North Ring Road in Lanzhou to the northern slope protection of Tianyuan No. 9, exposing more particles. The road is blocked by falling sand and stones from the landslide, and there is a potential safety hazard of further sliding. After the disaster, our province's geological disaster emergency experts Professor mengxingmin and Professor lizhiheng immediately went to the site of the accident, and used advanced instruments and technologies such as UAV photography and three-dimensional laser scanning to continuously monitor the landslide morphology, judge the stability of the landslide, prevent secondary disasters, and study the safety of road access, so as to provide important scientific basis and technical reference for disaster emergency disposal and road access in this section

on August 24, after a landslide occurred in Hanji Town, Linxia County, Linxia Prefecture, Professor Meng Xingmin, head of the flood control and rescue expert group of the Provincial Department of science and technology and professor of Lanzhou University, rushed to the geological disaster site in Hanji Town, Linxia county to participate in the disaster disposal on August 26, entrusted by the Provincial Department of science and technology and the Department of land and resources. Professor Meng Xingmin's team, together with experts from inside and outside the province such as the China Geological Environment Monitoring Institute, conducted a preliminary investigation and assessment of the landslide situation, and provided expert opinions on disaster disposal to the Provincial Department of land and resources according to the monitoring data and expert consultation opinions

it is due to the timely participation of many experts that the dangerous situation of "7.12" landslide at jiangdingya, Nanyu Township, Zhouqu County can be effectively solved. Because there is no plasticizer to resolve it, the formation of barrier lake in Zhouqu section of Bailong River is avoided, and the potential major dangerous situation is resolved. This fully illustrates the important role of experts in the design of boards and cards for scientific response to natural disasters

in recent years, the science and technology departments of our province and our city have actively supported scientific and technological innovation in the field of disaster prevention, mitigation and relief. Since 2017, our province has approved and supported 18 provincial science and technology projects in the field of disaster prevention and reduction, such as "research and development of Gansu earthquake quick report emergency information release system", "Research on underwater image disaster identification algorithm of reservoirs in the Yellow River Basin in Gansu Province", "intelligent control safety protection lifebed", "development and research of geological disaster monitoring and early warning and information management platform in mine accumulation areas", and then pressed the "drop hammer" key to actively support colleges and universities Scientific research institutions and enterprises carry out scientific and technological innovation in the field of disaster prevention, mitigation and relief. For the urgently needed key technologies of unmanned aerial vehicles such as disaster prevention, mitigation and disaster relief assessment and early warning, 1million yuan was invested to support Lanzhou University of technology to carry out "Research on Key Technologies of unmanned aerial vehicles", and strive to break through key technologies and provide new equipment for disaster prevention, mitigation and disaster relief
