We have used Finite Population Sampling and Lot Quality Assurance Sampling (LQAS) in a field survey of "immunization coverage rate" for EPI in three villages (towns) in Lanxi Zhejiang Province. The results showed that there was no significant difference (P > 0.05) between the rates of two samplings and between the rate of sampling and population. These results indicated that both Finite population Sampling and LQAS are cheap and simple, and can represent the immunization coverage level of population.
我们在浙江省兰溪市三个村（镇）的扩大免疫规划“免疫接种率”现场调查中采用了有限总体抽样和批质量保证抽样（LQAS）。结果显示，两种抽样方法的接种率之间以及抽样接种率与总体接种率之间均无显著差异（P>0.05）。这些结果表明，有限总体抽样和批质量保证抽样成本低廉且操作简单，能够代表人群的免疫接种覆盖水平。
