摘　　要：在泸州市2016-2020年大气降水监测数据的基础上,借助聚类分析、多元方差分析等统计分析手段,对原有降水监测点位进行优化研究,并验证优化结果。在遵循《酸沉降监测技术规范》(HJ/T 165-2004)点位布设要求的前提下,建立了降水监测点位评价体系,从原有7个降水监测点位中优化筛选出3个。优化后的点位对监测结果的影响显著性均>0.05,表明优化前后全市降水数据无显著性差异,该优化方案不会影响区域整体代表性。Based on the precipitation monitoring data of Luzhou from 2016 to 2020,the original precipitation monitoring sites were optimized by cluster analysis and multivariate analysis of variance,and the results were verified.In accordance with the requirements in“Technical Specifications for Acid Deposition Monitoring”(HJ/T 165-2004),an evaluation system of precipitation monitoring sites was established,three sites were selected from the original seven monitoring sites.The significance of the influence of the optimized sites on monitoring results was greater than 0.05,indicating that there was no significant difference in the precipitation data in the whole city before and after optimization,and the optimization would not affect the overall representation in the region.
