摘　　要：为衡量不同种类雨量观测仪器的测雨性能,对5种不同雨量计(称重式雨量计OTT Pluvio2、LTPG1500,翻斗式雨量计SL3-1、JDZ05,压电式雨量计RT型)开展了比测实验。结果表明:在实验设置的所有雨强下(10~260 mm/h),称重式雨量计OTT Pluvio2、LTPG1500测得的降雨量基本在±4%误差控制线范围内波动;翻斗式雨量计SL3-1测得的降雨量普遍低于4%的误差控制线,在雨强较大时,翻斗式雨量计JDZ05大多数能达到有关规范要求;压电式雨量计虽然可以定性分析雨强,但在定量方面测量精度偏差较大。比测结果可为研究人员合理选用雨量观测仪器提供科学依据。In order to measure the rainfall measurement performance of different types of rainfall observation instruments,five different rain gauges(weighing rain gauge OTT Pluvio2 and LTPG1500,tipping bucket rain gauge SL3-1 and JDZ05,piezoelectric rain gauge RT)were compared.The results show that the rainfall measured by the weighing rain gauge OTT Pluvio2 and LTPG1500 basically fluctuates within the range of±4%error control line under all rainfall intensities(10~260 mm/h)set in the experiment.The rainfall measured by the tipping bucket rain gauge SL3-1 is generally lower than the error control line of 4%.When the rainfall intensity is large,most of the tipping bucket rain gauge JDZ05 can meet the requirements of the relevant specifications;although the piezoelectric rain gauge can qualitatively analyze the rainfall intensity,it has a significant deviation in the quantitative measurement accuracy.The comparison results can provide a scientific basis for researchers to reasonably select rainfall observation instruments.
