摘要

摘要: 为了解广西钦州典型农业区表层土壤中Se含量水平和空间分布特征,系统分析Se含量分布的影响因素,为富硒土地的规划利用提供科学依据,在钦州市新光农场采集348件表层土壤样品,利用多元统计分析、冷热点分析、地理探测器等方法,讨论不同因素对Se元素分布的影响。结果表明: 研究区表层土壤中Se含量为0.07~2.56 mg/kg,平均值为0.91 mg/kg,89.38%的土壤样品符合富硒标准; Se含量在空间上呈聚集分布状态,热点区域主要位于研究区西部和西北部; 数理统计分析表明,以泥盆纪碎屑岩、碳酸盐岩为成土母质的土壤具有较高的Se含量,Al₂O₃和Fe₂O₃与Se含量相关性显著; 地理探测器分析表明,Al₂O₃、Fe₂O₃、成土母质和有机质含量对Se含量的空间变异能力解释能力较强。综合分析表明,成土母质和土壤理化性质是土壤Se含量空间分布的主要影响因素,研究对钦州富硒土地调查与利用有较好的参考价值。

Abstract: In order to analyze the content level and spatial distribution characteristics of selenium in the surface soil of typical areas in Qinzhou of Guangxi, and the influencing factors of selenium content distribution, and provide scientific basis for the planning and utilization of selenium rich land, the authors in this paper collected 348 surface soil samples from Xinguang Farm to discuss the impact of different factors on the distribution of selenium element, through multiple statistical analysis, cold and hot spot analysis, geographic detectors. The results Xinguang show that selenium content in the surface soil of the study area was 0.07-2.56 mg/kg, with an average value of 0.91 mg/kg, and 89.38% of the samples met the selenium enrichment standard. The spatial distribution of soil selenium content was aggregated, and the hot spots were mainly located in the western and northwestern part of the study area. The statistical analysis shows that soil derived from Devonian carbonate rocks and clastic rocks has higher selenium content, and there is a significant correlation between Al₂O₃, Fe₂O₃ and selenium content. Al₂O₃, Fe₂O₃, soil parent material, and organic matter content have strong explanatory power for the spatial variability of selenium content, by geodetector analysis. The comprehensive analysis shows that parent material and soil physicochemical property are the main factors affecting the distribution of soil selenium content. This research has good reference value for the investigation and utilization of selenium rich land in Qinzhou.
