China's urbanization has exceeded 64% and a large number of small and medium-sized cities are the key development areas in the new stage. In urban planning, it is very important to reveal the influence of environmental comfort on urban vitality to improve the life quality of residents in these towns. Thus, the study investigated the impact of environmental comfort on urban vitality using ordinary least squares regression in Wuxi County. Environmental comfort was assessed through a comprehensive analysis of a built-up area and urban vitality was represented by vitality intensity. In addition, the influence pathways were identified and model validation was verified. The conclusions are as follows: (1) Environmental comfort and urban vitality are distributed spatially similarly, and both gradually decline from the center to the periphery. It is high in the east and low in the west, high in the south and low in the north. (2) Population density, POI mixing degree, building density, and road network density have significant positive effects on urban vitality. Population density has the greatest impact on urban vitality. Building height, building age, and river buffer have significant negative effects on urban vitality. (3) The impact of comprehensive environmental comfort on urban vitality is positive, and in terms of time, the order of impact is afternoon > morning > evening. Finally, a method for assessing the impact of environmental comfort on urban vitality was constructed, and the promoting effect of environmental comfort improvements on the vitality was verified. These findings will fill the gap between urban physical space and social needs in planning practices and provide reference to improve vitality for urban planning in small and medium-sized cities.
中国的城市化率已超过 64%，大量的中小城市是新阶段的重点发展区域。在城市规划中，揭示环境舒适度对城市活力的影响，以提高这些城镇居民的生活质量非常重要。因此，本研究使用普通最小二乘法回归法，在无锡市研究了环境舒适度对城市活力的影响。通过对建成区的综合分析来评估环境舒适度，并用活力强度来表示城市活力。此外，还确定了影响途径并验证了模型验证。结论如下：（1）环境舒适度和城市活力在空间上分布相似，两者都从中心向边缘逐渐下降。东部高，西部低，南部高，北部低。（2）人口密度、POI 混合度、建筑密度和路网密度对城市活力有显著的正向影响。人口密度对城市活力的影响最大。建筑高度、建筑年龄和河流缓冲区对城市活力有显著的负向影响。（3）综合环境舒适度对城市活力的影响是正向的，从时间上看，影响的顺序是下午>上午>晚上。最后，构建了一种评估环境舒适度对城市活力影响的方法，并验证了环境舒适度改善对活力的促进作用。这些发现将填补规划实践中城市物质空间与社会需求之间的差距，为提高中小城市的活力提供参考。
