为探明鄂北岗地耕地土壤质量及影响因素情况,以湖北省枣阳市为研究区,选择样点240个,以土壤有机质土壤有机质（SOM）含量为研究对象,运用经典统计学、地统计学对耕地土壤有机质含量空间格局进行分析,引入地理探测器Geodetector模型结合佩尔森（Pearson）相关系数法,得出影响枣阳市土壤有机质含量空间格局的显著性因子。结果表明:（1）枣阳市耕地土壤有机质含量分布空间格局呈弱变异,空间变异模型为球状模型拟合,分布格局呈现四周高,中心向东北向偏低的空间格局;（2）对土壤有机质含量单因子影响最强的5种因子均为降水量、土壤类型、NDVI、地表起伏度、公路距离;（3）各因子交互作用解释力均大于...

In order to explore the soil quality and influencing factors of cultivated land in the north of Hubei province, Zaoyang City, Hubei Province was selected as the research area, 240 samples were selected, soil organic matter (SOM) was the research object, and classical statistics and geostatistics were used. Analyzing the spatial pattern of cultivated land SOM, introducing the geodetector Geodetector model combined with the Pearson correlation coefficient method to calculate the significant factors affecting the spatial pattern of SOM content in ...
