| 摘要: |
| 选择云浮市 15 个镇（街道）的森林土壤钙、镁、硫含量为研究对象，比较分析其空间变异
性。结果显示：研究区森林土壤交换钙含量在 0.232~0.984 g · kg -1 之间，含量较高的有富林和高村，含量
较低的为云城和河口；森林土壤交换镁含量在 0.048~0.095 g · kg -1 之间，含量较高的有高村和都杨，含量
较低的为云城和高峰；森林土壤全硫含量在 0.126~0.235 g · kg -1 之间，含量较高的有思劳和石城，含量较
低的为腰古和高峰；土壤交换钙、交换镁间存在极显著的正相关关系，交换钙与全硫间存在极显著的负
相关关系，交换镁与全硫间则没有显著的相互关系。 |

| Abstract: |
| The spatial variabilities of soil calcium, magnesium and sulfur were compared in the forest of 15
towns of Yunfu city, Guangdong province. The results are as follows: The forest soil exchange calcium content of
0.232~0.984 g · kg -1 , the higher the content of Fulin and Gaocun, the lower the content of Yuncheng and Hekou. The
forest soil exchange magnesium content of 0.048-0.095 g · kg -1 , the higher the content of Gaocun and Duyang, the
lower the content of Yuncheng and Gaofeng. The forest soil total sulfur content of 0.126-0.235 g · kg -1 , the higher
the content of Silao and Shicheng, the lower the content of Yaogu and Gaofeng. There was a significant positive
correlation between calcium exchange and magnesium exchange, a significant negative correlation between calcium
exchange and total sulfur, and no significant correlation between exchange magnesium and total sulfur. |
