Research in the translocation and transformation of phosphorus in soil - water system is of importance to environmental p management and controlling the eutrophication . a series of experiments and investigations in this paper were conducted to study the changes of p pool by a long - term applying fertilizer p , the translocation and transformation of phosphorus between interface of soil and water in relation to their environmental effects , using the upland fields from yellow soil area of guizhou province 在贵州中部地区，通过对有代表性的黄壤旱地进行采样分析和盆栽试验，对其磷库变化及其环境影响进行了研究，同时采用无界径流小区试验、野外坡面径流小区试验以及模拟降雨径流试验对坡旱地地表径流中磷的含量水平、形态特征、生物有效性、迁移规律、磷流失量及其影响因素进行了研究。
