| 摘 要： | 运用灰色关联分析方法,找到影响粮食生产能力的主要因素.经分析,影响湖北省粮食生产能力的主要因素为有效灌溉面积和种植结构,均为水灾害因子,其与粮食产量的关联度平均分别为:0.96和0.91,在所有影响粮食产量的因子中占前两位,故应加强水灾害治理,确保有效灌溉面积和合理调整种植结构,保证湖北省粮食安全.

| Abstract: | The main factors impacting grain production were studied by grey correlation analysis.The results were shown as follows.The main water disaster factors impacting grain production were effective irrigated area and planting structure,the relationship degree of which with grain yield is respectively 0.96 and 0.91 ranking the first two among all the selected factor.It was shown that water disaster influenced the grain yield heavily.So it is important to strengthen the governance of water-related disasters,such as endurance of the effective irrigation area and adjustment of the planting structure. |
