The invention relates to the technical field of sandstorm
disaster monitoring, and relates to a sandstorm flow real-time monitoring method and
system under regional environment characteristics. According to the method, the
soil moisture content, the soil compactness and the
vegetation coverage are collected, the initial dusting
wind speed threshold value is determined in combination with the real-time
wind direction and the historical log, the dusting
wind speed threshold value is dynamically corrected through the
earth surface wind resistance deviation coefficient, and the dusting
wind speed threshold value is compared with the real-time wind speed collected in the to-be-detected area to judge whether the wind sand flowing risk exists or not. When the wind sand flowing risk exists, the collected surface sand layer height change data and the real-time wind speed are subjected to
coupling analysis to determine the real-time wind sand index, so that prevention and control personnel visually master the wind sand damage degree, and meanwhile, the current wind sand
severity level and the wind sand flowing change trend are determined according to the real-time wind sand index; the prevention and control work is changed from passive disaster response to active prevention in advance, time is won for reinforcing protection facilities in advance and storing prevention and control materials, and the effect of effectively reducing
sand storm disaster loss is achieved.
