| 为系统查明河北平原区粮食产量的地质影响因子及其影响程度，在总结地貌类型、土壤类型、气候、水文等因子与粮食作物产量关系的基础上，构建地质因子指标体系，运用灰色关联法分析河北平原区小麦产量与各因子之间的灰关联度。结果表明，地质因子与小麦产量的灰关联度排序为气候＞水文地质子区＞土壤类型＞地层＞地貌＞水文地质区，气候对河北粮食产量的影响更大，但各因子与小麦产量的灰关联度相差不大,说明各地质因子均对小麦产量有影响，无单一因子占主导地位。研究成果对提高河北粮食产量、促进区域农业可持续发展具有重要意义。 |

| Abstract: |
| To systematically determine the geological influencing factors and their degree of influence on grain output in the Hebei Plain region, a geological factor index system was constructed based on a summary of the relationships between factors such as geomorphic type, soil type, climate, hydrology and grain crop yield. The grey relational method was then employed to analyze the degree of grey correlation between wheat yield in the Hebei Plain region and each factor. The results indicate that the order of the degree of grey correlation between geological factors and wheat yield is as follows: climate > hydrogeological subregion > soil type > stratum > geomorphology > hydrogeological region. This demonstrates that climate has a relatively greater impact on grain yield in Hebei Province. However, the degrees of grey correlation for all factors are relatively close, suggesting that each geological factor exerts an influence on wheat yield, with no single factor being overwhelmingly dominant. This study is of significant importance for increasing grain yield in Hebei Province and promoting the sustainable development of regional agriculture. |
