摘要:

利用山西省5个酸雨观测站自动和人工测定的pH、电导率等数据进行分析,评估两种观测方法的结果差异。结果表明:平行观测期间5个站降水采样情况正常,自动观测降雨次数缺测率为3.6%,仪器全年无故障运行时间达到99.0%。就pH测量而言,研究期间人工观测的非酸雨(pH>5.6)次数占比为86.9%,低于自动观测结果(91.5%)。人工观测值和自动观测值相对pH偏差在20%以内的观测次数占比为91.25%。电导率K值测量,两种方法相对偏差在20%以内的观测次数占比64.1%。5个观测站中电导率的人工与自动观测线性相关性明显高于pH。总体来说,仪器运行较为可靠,但平行观测期间人工观测值与自动观测值仍存在一定差异,建议延长平行观测时间。

Abstract:

The pH and conductivity data measured automatically and artificially from five acid rain observation stations in Shanxi province were analyzed to evaluate the discrepancy between the two observation methods.The results show that the precipitation sampling of the five stations is normal during parallel observation, the missing rate of automatic observation is 3.6%, and the trouble-free operation time of the instrument reaches 99.0%.In terms of pH measurement, 86.9% of non-acid rain (pH>5.6) was observed artificially during the study, which was lower than that of automatic observation (91.5%).The proportion of observation times with the relative pH deviation of manual and automatic observation values within 20% was 91.25%.For the measurement of the conductivity K value, the number of observations with a deviation between the two methods within 20% accounted for 64.1%.The linear correlation between artificial and automatic measurements of electrical conductivity at the five observation stations is significantly higher than that of pH.In general, the operation of the instrument is relatively reliable, but there are still some discrepancies between the artificial and automatic observations during parallel observation.Therefore it is recommended to extend the parallel observation time.
