中文摘要:
      以四川农业大学成都校区为监测点,采用大气主动采样法(AA)、大气干表面法(ADS)及大气湿表面法(AWS)3种常用干沉降采集方法做大气磷干沉降通量对比试验。结果表明,3种采样方法获得的大气磷干沉降通量间具有显著的差异性及相关性(P<005),三者间可以进行换算统一;AA法适用于较短采样周期的连续性监测研究,ADS法适用于较长采样周期(5 d)的监测研究,而AWS法更适用于在长采样周期(月)内选取一段时间作为干沉降监测的研究。
英文摘要:
      Taking Sichuan Agricultural University Chengdu Campus as the monitoring site, atmospheric phosphorus dry deposition flux was studied by comparing 3 common sampling methods, i.e. atmospheric active sampling method (AA), 〖JP2〗atmospheric dry surface method (ADS) and atmospheric wet surface method (AWS). The results showed that the 3 sampling methods had significant difference and correlation(P<0.05), and could be converted to unification. AA was suitable for continuous monitoring in a short sampling period, ADS was suitable for longer sampling period (5 days), AWS was more suitable for selecting some time in a long sampling period(month).
