2023年台南市遭受严重的登革热疫情,其传播受到复杂的环境因素影响。分析台南市登革热传播的时空特征,并厘清影响其传播的关键气候因子,可为本地化的疫情监测及科学防控提供参考依据。本研究使用标准差椭圆、莫兰指数、相关性分析、多重共线性诊断以及贝叶斯时空模型,对2023年1—12月台南市的月登革热病例数据和气象记录进行了分析。研究发现,台南市2023年全年病例数时间上呈现“上升-高峰-下降”的变化趋势,空间上表现为“散发-随机-聚集-消退”的模式。各气候因子的相对风险排序依次为降雨日数

日照时数,不同区域登革热发病风险差异显著,东区、永康区、安平区、北区为高风险区;降雨日数与平均气温是影响登革热传播的关键气候因子。
In 2023, Tainan experienced a severe dengue fever epidemic, the spread of which was influenced by complex environmental factors. This study analyzes the spatiotemporal patterns of dengue fever transmission in Tainan and identifies the key meteorological drivers, aiming to provide a scientific basis for local surveillance and evidence-based prevention. Monthly dengue case data and meteorological records for Tainan from January to December 2023 were analyzed using a standard deviational ellipse analysis, Moran’s
I
, correlation analysis, multicollinearity diagnostics, and a Bayesian spatiotemporal model. The findings reveal a clear temporal pattern of “increase-peak-decline” in case numbers for the full year of 2023. Spatially, the epidemic evolved through four stages:sporadic occurrence, random distribution, clustering, and eventual dissipation. The relative risks of meteorological factors followed the order: number of rainy days

sunshine duration. The risk of dengue infection varied significantly across districts, with high risk concentrated in the East, Yongkan
g, Anping, and North Districts. The number of rainy days and average temperature were identified as the most critical meteorological drivers. The study provides evidence that targeted interventions focusing on high-risk districts, combined with meteorological early warning systems, can effectively support dengue control.
