以关帝山文峪河上游3种典型河岸林为研究对象进行了外源氮磷输入试验。通过对土壤定期取样、试验室化验分析，对不同河岸林外源氮磷加载前后土壤属性进行分析，结果表明：外源氮磷输入前土壤全氮和硝态氮含量、土壤pH值及土壤含水量在不同类型河岸林之间的差异都达到极显著水平（p＜0．01），土壤全磷、速效磷和铵态氮含量差异不显著；外源氮输入后土壤全氮、硝态氮、速效磷、含水量在不同类型河岸林之间表现极显著差异；外源磷输入后3种河岸林土壤全磷含量差异不显著，而其它属性指标均表现出极显著性差异。

Taking three types riparian forest of upstream in Wenyu river as study object , the test studied the influence of ni-trogen and phosphorus inputs .Through regularly collecting , testing and analyzing the soil , it analyzed the soil properties before and after exogenous nitrogen and phosphorus inputs in different riparian forests .The results were as follows:before exogenous nitrogen and phosphorus input , difference of soil total nitrogen and nitrate content , pH and the soil moisture con-tent in different riparian forests reached extremely significant level (p<0.01), soil total phosphorus and available phos-phorus were no significant difference;after exogenous nitrogen input , soil total nitrogen , nitrate nitrogen , available phos-phorus, water content showed significant difference between different riparian forests ; after exogenous phosphorus input in three kinds riparian forest soil , total phosphorus content was not significant difference , while all the other property indexes showed significant differences .
