| 摘 要： | 应用统计学的分析技术,对砀山县城内各土属土壤有机质含量及土壤有机质水平分布特征进行了分析。结果表明,砀山土壤有机质平均含量差异较大,最高淤土属有机质含量为1.09%,最低飞沙土属有机质含量仅为0.42%。砀山土壤有机质含量普遍较低,4、5、6级占分布面积的82.59%,平均为5级。相关分析显示,土壤有机质与土壤水分呈极显著正相关关系,相关系数为0.843,与pH值呈中等负相关,相关系数为-0.697,与土壤客重呈显著的负相关关系,相关系数为0.809。

| Abstract: | With the application of statistical analysis,the contents and distribution of soil organic matter in Dangshan County were analyzed.The results showed that the average content of organic matter in Dangshan soils had significant differences.The organic matter was highest up to 1.09%in the silt soil,but lowest with only 0.42%in sand.The organic matter contents of the soil were generally low in Dangshan County,the totsl distribution areas of 4,5,6-class were up to 82.59%with an average of class 5.Correlation an... |
