摘 要 ：本文通过对海河流域土壤中磷及其形态含量的分析结果，计算出该流域土壤中磷的库存量为6.4210¹⁰kg。并以成土母质、人畜粪、化肥施入量和径流带入量、大气降尘及植物的残留量等因素为对土壤中磷的贡献；同时以径流的带出，大气的飘尘及植物体茎叶等因素为磷的迁出部分，计算出海河流域土体中磷的进出量分别为4.2410⁸kg/a和3.6610⁸kg/a，以此来研究其通量关系。

Abstract:he amount of phosphorus reserved in soil in the Haihe River basin is estimated at 6.6210¹⁰kg,based on a computation of the analytical results for all the species of phosphoruspresent in soil. The input of phosphorus is 4.2410⁸kg/a which was calculated from the con-tributions of earth-forming parent material . human and animal wastes applied as manure ,chemical fertilizers , surface runoff, air dust deposition and plant residues ,to the phosphorusin soil. And the output of phosphorus is 3.6610⁸kg/a...
