依据陕西省生态农业干旱相似区,将陕西省干旱预测预警划分为8个分区;利用中期或延伸期天气预报、土壤相对湿度观测值、地面植被等信息,分别建立了综合气象和综合农业干旱预测模型,开发了陕西省干旱预测预警系统平台,可逐日对全省97个气象站点未来的干旱演变进行滚动预测,在此基础上结合干旱预警条件分析及等级判识,进一步判断是否发布以及如何发布干旱预警信息.与实际出现的旱情相比,2007年的干旱预测准确率达88%~96%.
依據陝西省生態農業榦旱相似區,將陝西省榦旱預測預警劃分為8箇分區;利用中期或延伸期天氣預報、土壤相對濕度觀測值、地麵植被等信息,分彆建立瞭綜閤氣象和綜閤農業榦旱預測模型,開髮瞭陝西省榦旱預測預警繫統平檯,可逐日對全省97箇氣象站點未來的榦旱縯變進行滾動預測,在此基礎上結閤榦旱預警條件分析及等級判識,進一步判斷是否髮佈以及如何髮佈榦旱預警信息.與實際齣現的旱情相比,2007年的榦旱預測準確率達88%~96%.

Based on the ecological and agricultural drought similar regions, 8 sub-areas for drought forecasting and early warning in Shaanxi province were divided. By using the information of medium term or extended weather forecast, soil relative humidity observations, ground vegetation, etc, integrated meteorological model and the integrated agricultural model for drought forecasting were set up and a drought forecasting and early warning system platform was developed. The daily drought evolution of the 97 meteorological stations in Shaanxi province could then be rolling forecasted. Whether and how to release drought early warning information could be determined based on these records, the analysis of drought early warning conditions and identified grades. The accuracy rate of drought prediction in 2007 was 88% to 96% as compared to the actual situation.
