Abstract
Soil properties are crucial in forest ecological management and rare vegetation protection. In this study, Fanjing Mountain, a typical subtropical forest, was used to investigate and analyze the differences in soil properties and climate change characteristics of Fanjing Mountain in 1982 and 2014. Then redundancy analysis was used to analyze the influence of climate factors on soil properties. The results showed that: 1) Compared to 1982, the soil properties of Fanjian Mountain changed significantly in 2014. The soil texture evolved from a silty loam in 1982 to a silty clay loam in 2014. There was a significant increase in soil clay particles. In addition, the soil showed acidification, weakened cation exchange capacity, and relatively stable soil total nitrogen but significant loss of soil organic matter and total phosphorus nutrients. 2) In the past 32 years, the environmental climate of Fanjing Mountain has shown the characteristics of increasing annual average temperature and annual rainfall, frequent extreme temperature, widening the annual temperature range and decreasing annual relative humidity. 3) Soil type and maximum annual temperature have a highly significant effect on the evolution of soil properties, while annual rainfall and slope orientation significantly affect the evolution.
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
