东阿县玉米精细化气象灾害风险评估与区划

The Refined Meteorological Disaster Risk Assessment and Zoning of Corn in Dong′e County

鲁西平原是主要的玉米的产区,同时也是气象灾害的频发区,因此加强鲁西平原地区夏玉米气象灾害风险评估与区划有着重要的意义。以东阿县为例,利用当地气象观测数据,结合GIS技术对夏玉米的干旱、高温、渍涝等气象灾害进行风险性评估与区划。结果表明院玉米综合农业气象灾害风险度为0.25耀0.30,各乡镇综合气象灾害风险度均在轻微灾害风险区。牛角店镇玉米综合气象灾害风险度最小,为0.25;姚寨镇最高,为0.30。全县玉米气象灾害风险较小,适合玉米的种植。

Luxi Plain is not only major corn-producing areas,but also prone areas of meteorological disasters,thus it is very significant to enhance summer maize meteorological disaster risk assessment and zoning in Luxi Plain. A case study of Dong＇e County,using local meteorological data, combined with GIS technology,risk assessment and zoning of drought,high temperature,waterlogging and other weather disasters were conducted. The results showed that integrated agricultural meteorology disaster risk degree of Maize was between 0.25 to 0.30, integrated meteorological disaster risk degree in the townships were slight.Niujiaodian corn integrated meteorological disasters risk degree was minimum （0.25） ;Yaozhai corn integrated meteorological disaster risk degree was maximun （0.30）.Corn meteorological disaster risk in the whole county is small, which is suitable for the cultivation of corn.
