摘要
为探讨不同坡地汇水区内磷元素流失特征及差异,本研究在柴河小流域选取了4个有代表性的汇水区,测定了旱季、雨季表层土壤磷含量。结果表明,雨季表层土壤全磷含量高于旱季,有效磷含量除了人为影响较大的汇水区外,都是雨季低于旱季。
In order to explore the characteristics and differences of phosphorus loss in different sloping catchment areas,four representative catchment areas were selected in the small basin of Chai River.The phosphorus content of surface soil in dry season and rainy season was determined,respectively.The results showed that the total P content of surface soil in rainy season was higher than that in dry season,and the available P content was lower in rainy season than that in dry season except for the catchment area with great anthropogenic influence.The results of initial and intermediate rainfall runoff samples showed that the phosphorus loss concentration in the No.4 catchment area was higher than that in other areas.
