摘　　要：采集并分析泉州市耕地表层土壤样品3607个,应用统计分析方法研究耕地土壤有效硼含量空间分布及其影响因素。结果表明:泉州市耕地土壤有效硼含量整体较缺乏,有效硼含量范围为0.01~1.90 mg·kg^(-1),土壤有效硼含量平均为0.33 mg·kg^(-1),79.5%的耕地土壤有效硼含量处于很低或极低水平。土地利用方式、土壤类型、海拔高度、土壤理化性质等均对土壤有效硼含量有不同程度影响,土壤有效硼含量区域差异较大,高海拔地区显著低于低海拔地区。泉州市耕地土壤普遍缺硼,施用硼肥极有必要。A total of 3607 surface soil samples in the cultivated land of Quanzhou City were collected and analyzed.The spatial distribution of available boron content in the cultivated soil and its influencing factors were studied by using the statistical analysis method.The results showed that:the content of available boron in the cultivated soil of Quanzhou City was relatively deficient on the whole.The content of available boron ranged from 0.01 to 1.90 mg·kg^(-1),and the average content of available boron in the soil was 0.33 mg·kg^(-1).The content of available boron in 79.5%of cultivated soil was at a low or very low level.The land use types,soil types,altitude,soil physical and chemical properties had different effects on the content of available boron in soil.The content of available boron in soil varied greatly,and the content of available boron in the high altitude area was significantly lower than that in the low altitude area.Boron was generally deficient in the cultivated soil in Quanzhou City,so it was necessary to apply boron fertilizer.
