摘要
文章讨论了氮磷在土壤中的赋存形式,及其迁移转化规律,即氮磷从土壤圈向其它圈层特别是水圈扩散的过程;并讨论了氮磷的积累与流失的关系,认为磷主要是受累积平衡影响,而氮则受生物控制程度更大。同时也说明了土壤氮磷流失对水体污染和水体富营养化的影响。
The forms of existence of nitrogen and phosphorous in soil are discussed. The transferring and transforming of nutrients, namely, is a process of that nitrogen and phosphorous diffuse from the hydrosphere to the geosphere. To recognize the relationship between the accumulation and the loss of N and P is very important for control nutrients. The predominant effects to phosphorous is accumulation balance, while to nitrogen is microbiological processes. The paper mentions the loss of N and P from farmland, the water pollution and the effect of water eutrophication. Then it will threaten the health of people.
