【Abstract】 The risk assessment and prediction of apple blooming freezing injury is of great importance in promoting the rational planning and layout of apple industry and reducing the meteorological disaster losses.Here the index of freezing injury risk rate was taken as an index to assess the risk of freezing injury in apple base counties of Shaanxi Province.Based on the numerical weather prediction model and GIS technology the medium-term and short-term blooming freezing injury forecast models were developed,which make the temperature forecast areas of freezing injury extend to county level and realize the operational explanation application.更多还原
