| 通过土壤元素相似度分析，构建名优特选区评价标准，评价葡萄名优特选区的适宜性，优化种植布局并提升土壤资源利用效率。基于河北东部平原区多目标地球化学调查数据，系统筛选25项土壤元素指标，采用最小-最大标准化方法消除量纲差异，构建规范化评估矩阵；结合欧氏距离模型，量化样点与昌黎名优特选区的空间相似度，划分葡萄种植适宜等级。结果显示，河北平原葡萄种植适宜性呈显著梯度分异，最适宜区（占3.7%）、适宜区（占16.7%）、次适宜区（占40.0%）及不适宜区（占39.6%）的面积分别为2 988、13 568、32 500、32 216 km2，其中最适宜区绝大部分分布于秦皇岛—昌黎、唐山滦县交界及石家庄周边花岗岩母质发育的淋溶褐土带，证实成土母质专属性是名优特选区形成的核心控制因素，建立的相似度评价标准可实现平原区土壤物源的精准追踪。研究成果可为名优农业精准区划与特色农产品品牌建设提供可量化的技术支持。 |

| Abstract: |
| This study establishes evaluation criteria for high-quality specialty zones using soil element similarity analysis, aiming to assess the suitability of such zones for grape cultivation, optimize planting layouts, and improve soil resource utilization efficiency. Based on multi-target geochemical survey data from the eastern plain of Hebei Province, 25 soil element indicators were systematically selected. The min max normalization method was applied to eliminate dimensional differences and construct a standardized evaluation matrix. The Euclidean distance model was then employed to quantify the spatial similarity between each sample point and the Changli high quality specialty zone, based on which the suitability levels for grape planting were classified. The results show that grape planting suitability in the Hebei Plain exhibits a significant gradient differentiation. The areas classified as most suitable, suitable, moderately suitable, and unsuitable were 2,988 km2(3.7%), 13,568 km2(16.7%), 32,500 km2(40.0%), and 32,216 km2(39.6%), respectively. The vast majority of the most suitable areas are distributed within leached cinnamon soil zones developed from granite parent materials, mainly in the Qinhuangdao-Changli region, the border area of Luanxian County in Tangshan, and the vicinity of Shijiazhuang. This study confirms that the specificity of soil parent material is the key controlling factor in the formation of high-quality specialty zones. The proposed similarity evaluation standard enables precise tracing of soil provenance in plain areas. The findings provide quantifiable technical support for the precise zoning of high quality agriculture and the branding of characteristic agricultural products. |
