| 摘要: |
| 【目的】以白水县为例，针对陕西省苹果膨大期高温热害风险灾害进行精细化风险评估与区划，为县级政府规划苹果产业发展及建立防灾减灾机制提供参考。【方法】利用白水及周边县气象站1971-2010年6-7月逐日日最高气温以及28个区域气象站2010-2012年6-7月逐日日最高气温，建立白水县苹果膨大期高温热害危险性风险评估模型，并对其高温热害风险进行评估与区划。【结果】白水县东北和东南地区处于高温热害重度风险区，县中东部和西部大部地区分别处于中度和轻度风险区，这与客观事实较为一致，说明该风险区划结果能准确反映白水县苹果膨大期高温热害风险。【结论】利用区域气象站资料及高温热害危险性风险评估模型，可得到较为准确的高温热害区划结果。 |

| Abstract: |
| 【Objective】Taking Baishui county as an example,this paper conducted refined risk assessment and regionalization of heat injury during enlargement period of apple in Shaanxi province,to improve apple industrial development and establish disaster prevention and mitigation mechanism for county level government.【Method】A climate risk assessment model was established based on daily maximum temperature in Baishui county and nearby weather stations from June to July in 1971-2010,as well as 28 regional weather stations from June to July in 2010-2012.The model was used to assess and regionalize the risk of heat injury in apple enlargement period in Baishui county.【Result】Northeast and southeast areas of Baishui were in severe risk of heat injury,and the most area of north and central area were in moderate and mild risk,respectively.The result was consistent with the actual values,indicating that the assessment and regionalization were able to accurately reflect the heat injury risk.【Conclusion】Accurate risk assessment and regionalization could be obtained using regional weather data and the established climate risk assessment model. |
