摘要：

为明确河北省巨鹿县农用土壤肥力状况，指导区域农业可持续发展，本研究系统采集土壤样品1628份，分析土壤有机质、全氮、有效磷、速效钾、pH等关键肥力指标，利用隶属度函数计算土壤综合肥力指数，进行土壤质量综合评价。结果表明：巨鹿县农用土壤普遍呈弱碱性（均值pH 8.24），有机质含量偏低（均值9.97 g/kg）、有效磷不足（均值11.62 mg/kg），是土壤肥力的主要限制因素。巨鹿县各乡镇土壤综合肥力指数介于0.58~0.62，空间分布呈西高东低、中部向南北递减趋势。全氮、有效磷、有机质、有效锰和有效铜的变异系数较高，分别为0.36、0.33、0.35、0.45和0.41，表明其空间异质性显著。研究结论强调，提高巨鹿县土壤肥力，应重点关注有机质和有效磷的提升。建议采取有机物料增施有机物料和磷肥配施的综合措施，有效提高该地区土壤综合肥力状况，推动该地区农业的可持续发展。

Abstract:

In order to clarify the status of agricultural soil fertility in Julu County of Hebei Province and guide the sustainable development of regional agriculture, 1628 soil samples were systematically collected in this study. The key fertility indexes such as soil organic matter (SOM), total nitrogen (TN), available phosphorus (AP), available potassium (AK), and pH value were analyzed. The membership function was used to calculate the comprehensive fertility index (SCFI) of soil, and the soil quality was comprehensively evaluated. The results showed that the soils in Julu County were generally weakly alkaline, with an average value of pH 8.24. Specifically, SOM content was relatively low (average: 9.97 g/kg), TN was relatively abundant (average: 1.36 g/kg), AP was insufficient (average: 11.62 mg/kg), AK was enriched (average: 203.83 mg/kg), available iron (Avail-Fe) was at an appropriate level (average: 7.88 mg/kg), available manganese (Avail-Mn) was abundant (average: 23.15 mg/kg), while available copper (Avail-Cu) (average: 16.50 mg/kg) and available zinc (Avail-Zn) (average: 50.72 mg/kg) exceeded the standard limits. Among these indicators, the coefficients of variation (CV) of TN, AP, SOM, Avail-Mn, and Avail-Cu were relatively high, being 0.36, 0.33, 0.35, 0.45, and 0.41, respectively. The SCFI of soils in various towns and townships of Julu County ranged from 0.58 to 0.62, and their spatial distribution presented a pattern of being higher in the west and lower in the east, and decreasing from the central area to the north and south. Soil fertility was mainly affected by SOM, AP, and TN. Appropriately increasing the application of organic materials and applying phosphate fertilizer in a certain proportion could effectively improve the comprehensive soil fertility of this region, thereby further promoting the sustainable development of local agriculture.
