    Analysis of Distribution and Influencing Factors of Three-Nitrogen in Groundwater of the Liuxi River Basin by PANG Yuan, ZENG Hui, ZHANG Mingzhu, ZHUO Quanlong, GUO Zhengguo

    Published 2021-01-01
    “…Based on the monitoring data of 28 sampling points in the study area from 2012 to 2018,the distribution characteristics and influencing factors of groundwater three nitrogen in Liuxi River Basin were analyzed.The results showed that the mass concentrations of ammonia nitrogen,nitrate nitrogen and nitrite nitrogen in groundwater in the study area showed a downward trend with time,and the annual decreasing ranges were 0.220,0.120 and 0.001 mg/L,respectively;the mass concentrations of ammonia nitrogen and nitrate nitrogen in the middle reaches were 1.1 and 1.6 times higher than those in the lower reaches,respectively;the average mass concentrations of ammonia nitrogen,nitrate nitrogen and nitrite nitrogen in bedrock fissure water were 3.2,0.1 and 0.7 times of that in loose rock pore water,respectively;the correlation degree of ammonia nitrogen and pesticide and fertilizer application was greater,the correlation degree of nitrate nitrogen and nitrite nitrogen and waste water discharge was greater;and three-nitrogen was affected by rainfall to a certain extent,but the correlation was poor;ammonia nitrogen and nitrate nitrogen were closely related to the redox condition and runoff condition of groundwater.…”
