Early Warning of Snow Disaster in Pasturing Areas of Inner Mongolia

Using ground and remote sensing monitoring,and national standards of snow disaster monitoring evaluation standards,quantitative evaluation of snow disaster was realized. Threshold of animal husbandry weather forecast indexes were applied to establish snow disaster early warning for different grasslands in pasturing areas of Inner Mongolia,and make the grade distribution map of snow disaster early warning. The forecast results basically met the real conditions,it proved that this forecast method was capable of evaluating scale and influence degree of snow disaster. However,the snow disaster grade forecast deviated from the real conditions for the influence of weather forecast accuracy rate.
