Abstract
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
