摘要

以马鞍山西北坡土壤作为研究对象

利用不同时间不同海拔高度土壤的试验数据

分析了坡面土壤氮磷含量的时空变异特征和次降雨前后土壤颗粒组成与氮磷含量的变化特征

进行了坡面土壤及氮磷元素移失量的估算。结果表明

速效磷含量由1月到7月呈增加趋势;土壤全磷含量随着时间变化而逐渐降低

在空间上随海拔高度降低而逐渐增加;土壤的全氮与水解氮在季节上表现出春季较高

而夏季较低的特点

在空间上呈从山体下部向上逐渐降低的趋势;降雨后

坡地表层土壤氮磷含量会有一定程度的降低

其中速效磷和水解氮降幅明显高于全磷和全氮

土壤颗粒组成呈现出粘粒和粉粒含量减少

砂粒含量相对增加的趋势;坡面土壤的平均流失厚度为0.41 cm/a

平均流失量为5 412 t/(km2.a)

氮素和磷素的平均移失量分别为9.12

2.30 t/(km2.a)。
