摘要
According to the distribution Weinan, the atmospheric precipitation characteristics of atmospheric precipitation in monitoring station of Weinan and atmospheric precipitation monitoring station of Nanjiao Village in Linwei District were set up. After one year of monitoring and analysis of the atmospheric precipitation in Weinan, the precipitation amount, pH value, and the change characteristics of conductivity of the atmospheric precipitation were obtained. The concentrations of five kinds of cation （Ca^2＋,NH^4＋,Mg^2＋,Na^＋,K^＋） and four kinds of anion （F^-,Cl^-,SO4^2-,NO3） in the precipita- tion of Weinan and Nanjiao Village were determined by ion chromatography. The results showed that the concentration of SO3 and NO3 in atmospheric precipitation of Weinan changed significantly, while there was no significant change observed on the concentration of F^-, Cl^-, Mg^2＋, K^＋ and Na^＋ in a year.
根据渭南地区大气降水量的分布特征,设立渭南市大气降水监测站和临渭区南焦村大气降水监测站。利用长达一年的时间监测和分析了渭南市的大气降水状况,具体得出渭南市大气降水的降水量,p H值,以及电导率的变化特征。同时采用离子色谱法测定了渭南市与临渭区南焦村降水中5种阳离子(Ca^(2+),NH^(4+),Mg^(2+),Na^+,K^+)和4种阴离子(F^-,Cl^-,SO_4^(2-),NO_3^-)的离子浓度。由此得出渭南市大气降水种SO_4^(2-)、NO_3^-离子浓度的变化幅度较大,而F^-、C^l-、Mg^(2+)、K^+和Na^+的离子浓度在监测的一年中变化幅度不显著。
