New Method of Measuring Different Sources of Nitrogen Pollution Load in Underground Aquifer

WANG Xi-feng;JIA Yang-wen;NIU Cun-wen;Institute of Quantitative & Technical Economics,Chinese Academy of Social Science;China Institute of Water Resources and Hydropower Research;  
The development of integrated simulation framework( IGESF) was implied to measure the nitrogen pollution source of groundwater environment. Considering the complexity of underground aquifer nitrogen sources of pollution measure,based on the theoretical basis of water cycle and associated processes,we constructed a IGESF with the distributed hydrological model,distributed model of water environment,numerical simulation of groundwater flow and contaminant transport model. In the measurement of underground aquifer source of nitrogen pollution,we also used the measured data ofgroundwater concentration of total nitrogen. At the same time,the north China plain was analyzed as a typical region according to the above method,and the north China plain from non-point source of nitrogen pollution of underground aquifers load is 38400 tons / year from1995 to 2004. The line source pollution from rivers is 26000 tons / year. The conclusion is basically equivalent to the integrated planning data of Haihe River Basin water resources.
