消落带土壤温度、湿度、电导率、pH值等属性是土壤物理、化学、生物等特性评估和生态修复的基础，但三峡库区湖北段消落带水淹强度差异对沿岸土壤属性的影响尚不明晰。为解决这一问题，将湖北段各区县消落带划分为无水淹（>175 m）、轻度水淹（175 m）、中度水淹（170 m）、重度水淹（<170）4个梯度，并于2024年5月原位监测不同水淹强度区域的土壤温度、湿度、电导率、pH值，利用统计和空间分析工具，初步揭示了其空间变异特性。结果表明：①三峡库区湖北段消落带土壤温度、湿度、电导率、pH值均值分别为32.45 ℃、12.58%、41.34 S/cm、6.75；②湖北段不同区县消落带土壤属性指标的变异性不同；③土壤属性变异系数大小排序方面，夷陵和秭归一致而兴山和巴东一致，地理位置、空间距离或许是影响其差异的主要原因。研究基于有限数据初步分析了湖北段消落带不同水淹强度土壤属性的变异特性，尚需多频次多指标（碳氮磷等）监测，为进一步揭示其时空变异规律、开展针对性生态修复提供技术支撑。

[Objective] Soil temperature， moisture content， electrical conductivity， and pH in the water-level-fluctuating zone are fundamental to assessing soil physical， chemical， and biological characteristics and conducting ecological restoration. This study aims to clarify the impact of varying flood intensity of the Hubei section of the Three Gorges Reservoir on soil properties in the water-level-fluctuating zone. [Method] This study divides the water-level-fluctuating zones of various counties in the Hubei section into four gradients： no flooding （>175 m）， light flooding （175 m）， moderate flooding （170 m）， and severe flooding （<170 m） zones. In May 2024， in-situ monitoring of soil temperature， moisture content， electrical conductivity， and pH was conducted in different flooding intensity zones. Statistical and spatial analysis were used to reveal their spatial variability characteristics. [Results] （1） The average values of soil temperature， humidity， electrical conductivity， and pH in the Hubei section of the water-level-fluctuating zone of the Three Gorges Reservoir are 32.45 ℃， 12.58%， 41.34 S/cm， and 6.75， respectively. During the monitoring period， soil temperatures ranged from 26.4 ℃ to 43.3 ℃， the average soil moisture content was 12.58%， the soil electrical conductivity showed significant variation， and the mean pH of the soil was 6.75. （2） The variability of soil properties in the water-level-fluctuating zone of different counties were varied. The soil temperature of Yiling exhibited a decreasing trend as the intensity of flooding decreased. The soil moisture of Zigui decreased as the flooding intensities decreased. The electrical conductivity of Xingshan was generally high， with most values exceeding 60 S/cm. The pH of Badong was consistent with other counties and districts， showing no obvious patterns of change， and remained stable between 6.0 and 7.0. （3） Soil temperature exhibited the highest coefficient of variation under moderate flooding. Under moderate， light， and no flooding conditions， the coefficient of variation decreased as flooding intensity decreased， with the lowest variability observed under no flooding conditions. Soil moisture variability was largely consistent under severe and moderate flooding conditions； the variability was basically consistent under light flooding and no flooding. The variability of electrical conductivity did not show a clear pattern with changes in flooding intensity. Under severe flooding， the coefficient of variation was the highest， while under no flooding， the coefficient of variation was the lowest. The variability of pH across different flooding intensities was generally low across counties， with the highest variability observed in the moderate flooding zone. （4） In terms of the order of variability in soil properties， Yiling and Zigui were consistent， while Xingshan and Badong were consistent. The variability of soil properties in Yiling and Zigui was as follows： electrical conductivity > soil moisture > soil temperature > pH， while that in Xingshan and Badong was as follows： electrical conductivity > soil temperature > soil moisture > pH. Geographic location and spatial distance may be the primary factors influencing these differences. [Conclusion] This study presents a preliminary analysis of the variability characteristics of soil properties in the Hubei section of the Three Gorges Reservoir area under different flooding intensities based on limited data. Further monitoring with multiple frequencies and indicators （such as carbon， nitrogen， and phosphorus） is needed to reveal the spatiotemporal variability patterns of soil properties in the Three Gorges Reservoir area and provide technical support for targeted ecological restoration efforts.
