Abstract
In order to study the impact of snow disaster on the construction and operation of PV power generation project in Inner Mongolia region,this paper uses observation data from 119 national meteorological stations in Inner Mongolia region,through GIS spatial analysis,applies meteorological disaster risk assessment theory and analytic hierarchy process to establish a snow disaster risk zoning model from the perspectives of three evaluation factors:risk of disaster causing factors,exposure of disaster-bearing bodies,and vulnerability of disaster-bearing bodies.The snow disaster risk zoning of PV power generation projects in Inner Mongolia region is studied.The research results show that the snow disaster risk distribution of PV power generation projects in Inner Mongolia region is gradually increasing from southwest to northeast.The low-risk areas are mainly distributed in Alxa League,the northern and southern parts of Bayannur City,the western part of Ordos City,the eastern part of Chifeng City,and most areas of Tongliao City.The sub-low risk areas are mainly distributed in the western eastern and central western part of Inner Mongolia region,parts of Chifeng City and Tongliao City,and the central part of Xing'an League.The medium risk areas are mainly concentrated in the northern part of Hohhot City,a small part of Baotou City,the central and western parts of Ulanqab City,and most of Xilingol League.The sub-high and high-risk areas are relatively concentrated,mainly distributed in a small part of Xilingol League and Hulunbuir City.For PV power generation projects in Inner Mongolia region,it is necessary to strengthen the pre assessment of snow disasters,incorporate snow disaster related parameters and reports into the influencing factors of the pre feasibility study evaluation of PV power generation projects,and improve the ability of the project to defend against snow disasters.Establish corresponding emergency plans for snow disasters,combine meteorological warning information or corresponding warning products from meteorological departments,improve emergency response mechanisms,and minimize the impact of snow disasters.关键词
