| 摘 要： | 应用历年气象、水稻产量资料和冷害指标,分析东北地区水稻低温冷害发生的温度条件、气候频率和风险概率,建立了水稻冷害气候风险度模式,将东北地区分成高、偏高、中等、较低和低风险5级水稻冷害气候风险度区.在气候风险性分析的基础上,考虑各地水稻冷害减产率、总产量和面积比例等经济损失因素,建立水稻生产对低温冷害反应的经济脆弱度模式...

| Abstract: | Applying calendar weather,rice yield data and chilling injury index of Northeast China,this paper analyzed thermal condition,occurrence frequency and risk probability of rice chilling damage,and developed an evaluation model of the climate risk index of the damage.Thus,Northeast China region is divided into five types of rice climate risk areas of highest,higher,medium,lower and lowest levels.In climate risk analysis,based on considerations the rice cold damage cut rates,total output and the area ratio and ... |
