| 摘 要： | 基于1961~2010年47个气象站和5个农气代表站气象资料、干旱灾情资料的收集和整理,分析了油菜生育期土壤相对湿度与降水距平百分率的关系,最终确定青海省油菜不同生育关键期干旱风险评估的实际阈值;并通过海拔、经度、纬度、油菜生育期旱灾发生频次的拟合方程,对青海省油菜不同生育期干旱进行风险区划,区划结果可以为科学、合理地防灾减灾、决策服务提供依据。

| Abstract: | Based on data of 47 meteorological stations, 5 agriculture representative stations and drought disaster during 1961-2010, the correla- tion of soil relative humidity and precipitation anomaly percentage in growth stage was analyzed, and the values of risk assessment of drought haz- ard was put forward. Through the fitting equation of elevation, longitude, latitude and percentage in growth stage, it revealed the risk assessment and division for drought disaster, the results will provide a basis for scare benefits for scientific and reasonable disaster prevention and decision- making service. |
