摘要： 通过分析核酸采样点的空间分布和资源配置情况，探索中心城市社区核酸采样点的可达性和公平性，旨在缓解日益增长的核酸采样需求与核酸采样点设施供给之间的矛盾，提高核酸采样服务的效率和公平性。以南昌市中心城区为研究区域，提出了基于多出行模式两步移动搜索法分析核酸采样点与人口的匹配性的研究方法来探索各种出行方式下核酸采样点的综合可达性，并基于洛伦兹曲线、基尼系数等非空间分析指标，对南昌市核酸采样点与人口的匹配性核酸检测点均等化水平进行评价。结果表明，南昌市整体的核酸采样点可达性较好，但仍处于不公平状态。

Abstract: This paper explores the accessibility and equity of nucleic acid sampling points in central city communities. By analyzing the spatial distribution and resource allocation of nucleic acid sampling points, this paper aims to address the growing demand for nucleic acid sampling, and improve the efficiency and equity of nucleic acid sampling services. The study focuses on the central urban area of Nanchang City and proposes a research method to assess the comprehensive accessibility of nucleic acid sampling points under various travel modes. The analysis includes matching nucleic acid sampling points with the population and evaluating the level of parity using non-spatial analysis indexes such as the Lorentz curve and Gini coefficient. The results indicate that while the accessibility of nucleic acid sampling sites in Nanchang is generally good, there is still an unfair distribution in terms of equity.

Key words: accessibility, nucleic acid sampling point, two-step floating catchment area method, multiple travel mode
