【摘要】 农业非点源磷的输出是造成地表水富营养化的主要因素之一,弄清土壤磷的流失机理可为进一步控制农田径流磷的流失提供理论依据。文章总结了国内外在土壤磷素循环研究成果,并对其加以评述,在此基础上分析了土壤磷素循环对研究土壤磷的径流流失的重要作用。更多还原

【Abstract】 Agricultural non-point output of phosphorus is one of the key factors in acceleration of eutrophication of surface waters. For controling soil loss of phosphorus further the principle of soil loss of phosphorus is need. In this paper the conclusions of study on soil circulation of phosphorus are discribed and discussed. Based on this the effects of the soil circulation of phosphosrus on the soil loss of phosphorus are analysised.更多还原
