城镇化是农村人口向城镇集聚、农村生产生活方式转变、农村地域向城镇地域转变的过程。县域城镇化是以县级城乡区域为空间单元、以县城为重要载体的城镇化。党的二十大报告明确指出县域城镇化是全面推进乡村振兴的重要助力。推进县域城镇化是我国国民经济结构战略性调整的重要抓手，也是我国乡村振兴和新型城镇化的必然选择。21世纪以来，随着经济发展和社会进步，贵州省城镇化水平快速提升，2000年至2020年贵州省城镇化率由23.96%上升至53.15%。本文利用2000年、2010年、2020年中国人口普查分县数据，借助ArcGIS 10.6软件平台对贵州省县域城镇化水平进行可视化分析，揭示贵州省县域城镇化发展格局及时空演变特征，采用地理探测器模型探讨贵州省县域城镇化格局的主要影响因素。研究结果表明：

（1）2000年至2020年，贵州省县域城镇化水平不断提高，县域城镇化水平的差异呈现出逐渐缩小的趋势；

（2）2020年，贵州省县域城镇化水平呈现出北高南低、东高西低的分布格局，县域城镇化水平高值区分布在贵阳市周围县域和贵州省北部地区，低值区分布在贵州省边缘地区；

（3）2000年至2020年，贵州省县域城镇化水平增长最快的区域是毕节市中西部地区、遵义市和铜仁市接壤地区。

（4）人均地区生产总值、二三产业产值占比、城镇居民人均可支配收入、人均社会消费品零售总额、平均受教育年限是贵州省县域城镇化发展格局的主要影响因素。

Urbanization is the process by which the rural population is concentrated in towns and cities, the rural mode of production and life is transformed, and the rural region is transformed into an urban region. With economic development and society progressing since the 21st century, the level of urbanization in Guizhou Province has increased rapidly, the urbanization rate in Guizhou Province has increased from 23.96% in 2000 to 53.15% in 2020. This study utilizes data from the 2000, 2010, and 2020 Chinese Census by county to conduct a visual analysis of county urbanization levels with the help of ArcGIS 10.6 software platform, revealing the development pattern and spatial-temporal variations characteristics of county urbanization in Guizhou Province, and exploring the main influencing factors of county urbanization patterns in Guizhou Province by using the geodetector model. The main results are summed up as follows:

(1) From 2000 to 2020, the level of county urbanization in Guizhou Province has been increasing, and the regional differences in county urbanization development have shown a trend of progressively decreasing.

(2) In 2020, the county urbanization development in Guizhou Province shows a distribution pattern of high levels in the northern and eastern regions and low levels in the southern and western regions. The high-value areas of county urbanization distributed in the counties around Guiyang City and the northern part of Guizhou Province, and the low-value areas distributed in marginal areas of Guizhou province.

(3) From 2000 to 2020, the fastest growing regions in Guizhou province in terms of county urbanisation levels are the central and western areas of Bijie, Zunyi and Tongren bordering areas.

(4) The development pattern of county urbanization in Guizhou Province is influenced by several key factors, including the per capita GNP, the proportion of output value of secondary and tertiary industries, the per capita disposable income of urban residents, the per capita total retail sales of social consumption, and the average years of education.
