| 摘 要： | 为研究山东省青州市土壤养分元素有效量及其影响因素，通过系统采集分析390件表层土壤样品，获得了N、P、K、Cu、Zn、Mo、B 7种土壤养分元素全量和有效量以及pH和有机质数据，并对其进行了相关性和差异性分析。结果表明：研究区土壤Mo、B元素有效量低，总体表现为缺乏和较缺乏；N元素有效量背景值略高于临界值，分布不规律；P、K、Cu、Zn元素有效量变异系数均大于100%，呈现西低东高的空间分布趋势。相关性分析表明，N、P、K、Cu、Zn、B 6种元素全量与有效量呈显著正相关，测试的7种元素有效量与pH均呈显著负相关，N、K、Zn、B 4种元素有效量与有机质含量呈显著正相关。不同成土母质中，奥陶系和寒武系土壤pH、奥陶系土壤有机质含量显著高于全区，养分有效量在奥陶系土壤中总体较低。不同土壤类型中，粗骨土土壤pH和有机质含量显著高于全区，养分有效量在粗骨土中总体较低。研究区土壤养分元素有效量不仅与元素全量水平关系密切，同时受土壤pH和有机质含量的影响。

| Abstract: | In order to study the available content of soil nutrient elements and their influencing factors in Qingzhou City, Shandong Province, 390 topsoil samples were systematically collected and analyzed. The total and available contents of soil nutrient elements such as N, P, K, Cu, Zn, Mo and B, as well as pH and organic matter content were obtained, and the correlation and difference were analyzed. The results showed that the available contents of soil Mo, B elements in the study area were low, and the overall performance was lack and relatively lack. The background value of N element available content was slightly higher than the critical value, and its distribution was irregular. The variation coefficients of P, K, Cu, Zn elements available contents were greater than 100%, showed a spatial distribution trend of low west and high east. The correlation analysis showed that the total contents of N, P, K, Cu, Zn, B elements were significantly positively correlated with available contents, and the available contents of the 7 elements tested were significantly negatively correlated with pH. In addition, the available contents of N, K, Zn, B elements had a significant positive correlation with organic matter content. In different parent materials, pH of Ordovician and Cambrian soil and organic matter content of Ordovician soil were significantly higher than the whole area, but the available contents of soil nutrient elements were generally lower in Ordovician soil. In different soil types, pH and organic matter content of coarse bone soil were obviously higher than the whole area, while the available contents of soil nutrient elements were generally lower. The available content of soil nutrient elements in the study area was not only closely related to the total content of elements, but also affected by soil pH and organic matter content. |
