摘要

在复杂的山地环境中，探索土壤酸碱度的变化规律对于准确管理土壤酸碱度和土壤的可持续利用具有重要价值。在本研究中，我们采集了 394 736 个田间表层土壤样本，并记录了贵州省的成对环境条件。采用空间自相关、半方差模型和地理检测器分析了土壤 pH 的空间结构特征和分布格局。结果表明，地表土壤 pH 值在 3.11 至 8.99 之间变化，变异系数为 17.14%。土壤 pH 呈斑块状镶嵌分布。气候、母质和地形等结构因素在控制 pH 值分异方面起着决定性作用。地理探测器分析表明，环境因子对土壤 pH 值分异的解释力依次为母岩（0.0976）>海拔（0.0144）>土壤温度制度（0.0112）>土地利用（0.00503）>土壤水分制度（0.000812）。母岩和海拔的相互影响非常明显。

Differentiation of Mountainous Soil pH and Its Influencing Factors in Guizhou Province, China

In the complex mountainous environment, it is valuable to explore the variation rule of soil pH for accurately managing soil pH and the sustainable use of soil. In this study, we collected 394,736 field surface soil samples and recorded the paired environmental conditions in Guizhou Province. The spatial autocorrelation, semi-variance model and geographical detector were employed to analyze the spatial structure characteristics and distribution pattern of soil pH. The results showed that the surface soil pH varies from 3.11 to 8.99, with the variation coefficient of 17.14%. Soil pH shows a patchy mosaic distribution pattern. The structural factors of climate, parent material, and topography play a determinant role in controlling pH differentiation. Geo detector analysis showed that the explanatory power of environmental factors for the soil pH differentiation is in the order of parent rock (0.0976) > altitude (0.0144) > soil temperature regime (0.0112) > land use (0.00503) > soil moisture regime (0.000812). The reciprocal effect of parent rock and altitude is noticeable.

期刊介绍： One of the most important challenges facing the contemporary scientific world are problems connected with environmental protection. Intensive development of industry and agriculture has led to a rise in living standards on one hand, but an increase in environmental degradation on the other. This degradation poses a direct threat to human health and life. Solving these ever-increasing problems which seriously endanger our civilization require the united efforts of scientists and field researchers of many branches. The "Polish Journal of Environmental Studies" publishes original papers and critical reviews on the following subjects: -Basic and applied environmental pollution research, including environmental engineering -Pollution control of atmospheric, water (marine and fresh), soil and biological materials -Determination of harmful substances, including their metabolic breakdown patterns -Analytical methods for metabolic breakdown patterns or other chemical degradation patterns in the environment and in biological samples -Development of new analytical methods, instruments and techniques for controlling pollutants -Circulation of pollutants in the environment and their effect on living organisms -Environmentally oriented catalysis -Hazards to human health and safety -Waste utilization and management -Land reclamation -Conference reports, scientific and technical reports and book reviews
