摘要
选取2021年1月—2022年5月乌鲁木齐市国家基本气象站、2021年1月—2022年12月伊宁国家基本气象站以及2020年4—12月、2021年1—8月、2022年3—5月喀什国家基准气候站的酸雨观测数据共计206条,开展自动和人工酸雨观测对比试验,分析pH值和电导率(K值)之间的差异。结果表明:(1)乌鲁木齐气象站和喀什气象站电导率的一致性明显大于pH值的一致性,乌鲁木齐气象站电导率和pH值数据均具有显著的线性正相关性,喀什气象站的电导率数据显示有较高的线性相关性,pH值的相关性则具有中等线性相关性,而伊宁气象站pH值和电导率的相关性都相对较弱;(2)乌鲁木齐气象站的pH值和电导率的人工观测和自动观测结果具有较好的相关性,喀什气象站的pH值人工观测和自动观测结果的相关性较差,伊宁气象站的降水的pH值和电导率的人工观测结果也与自动观测结果相关性较差;(3)人工观测和自动观测结果之间的差异可能是多种因素综合影响的结果,其中包括采样方式和观测方法的不同,以及观测时间的差异等,人工观测受制于观测人员的经验和操作水平,而自动观测则更加精确和稳定。此外,观测时间的不同也可能导致观测结果的差异,自动观测可以实时监测,避免了漏采或误采现象。
A total of 206 acid rain observation data were collected from the Urumqi National Basic Meteorological Station and the Yining National Basic Meteorological Station between January 2021 and May 2022,as well as from the Kashgar National Reference Climate Station during April to December 2020,January to August 2021,and March to May 2022.Comparative experiments were conducted to analyze differences in pH levels and conductivity(K value)between automatic and manual acid rain observations.This study results indicate that Urumqi and Kashgar meteorological stations have higher conductivity consistency than pH consistency.Urumqi station has a significant linear positive correlation between conductivity and pH,while Kashgar station has a high linear correlation for conductivity but only a moderate correlation for pH.Yining station has a weak correlation between pH and conductivity.In terms of parallel comparison correlation,Urumqi station has a good correlation for pH and conductivity manual and automatic observation results,while Kashgar station has a poor correlation for pH manual and automatic observation results,and Yining station has poor correlation for pH manual observation and precipitation conductivity results with automatic observation results.The difference between manual and automatic observation results may be due to various factors including sampling and observation methods,observation time,and the experience and operational level of observation personnel.Automatic observation is more accurate and stable.Intuitive observation can monitor in real-time,avoiding missed or erroneous mining phenomena.
