摘  要:
对渭河(杨凌段)水体的营养水平(主要是以磷为主)进行了调查研究。结果表明,渭河水体TP浓度为0.18 ̄1.47 mg.kg-1;平均为0.63 mg.kg-1,说明渭河水体TP已经开始富集了。在TP中,PP和DOP占TP的百分数明显比MRP所占的分值高。渭河水体的PP含量为0.056 ̄1.28 mg.kg-1,平均0.37 mg.kg-1,占TP的10.92% ̄87.34%;DOP含量为0.033 ̄0.33 mg.kg-1,平均为0.15 mg.kg-1,占TP的2.25% ̄62.64%;MRP含量为0.017 ̄0.39 mg.kg-1,平均为0.12 mg.kg-1,占总磷的3.17% ̄60.75%。

摘  要:
Eutrophication state of Weihe River,especially that of phosphorus state,was determined in the present study.The results showed that TP concentrations of Weihe River are in a range of 0.18~1.47 mg·kg-1,with mean value of 0.63 mg·kg-1,which meant that the content of phosphorus has accumulate sharply.The percentage of PP/TP and DOP/TP were found to be more than MRP/TP,as PP is in a range of 0.056~1.28 mg·kg-1,with mean value of 0.37 mg·kg-1 and PP/TP was discovered to be in a range of 10.92%~87.34%;while DOP was found to be in a range of 0.033~0.33 mg·kg-1,with mean value of 0.15 mg·kg-1;DOP/TP was to be in a range of 2.25%~62.64 %;MRP had 0.017%~0.39 mg·kg-1,with mean value of 0.12 mg·kg-1,accounting for 3.17%~60.75 % of total phosphorus,respectively.
