Abstract

Exploring the changes in microbial characteristics of soils in North China's plantation forests and the soil indicator measurement methods commonly used today can provide a certain degree of understanding of the current status of soils in North China's plantation forests. This study collected information on forest soil microbial laboratory testing methods and conducted mathematical statistics to get the current technical hotspots and development trends of microbial testing of forestry soils. Also organized overview of soil physicochemical properties and microbiological indicators of plantation forests in North China. The results show: 1) Current testing methods for forest soils could be broadly categorized as purely manual, combined manual and instrumental, and purely instrumental. Among them, the soil's physical properties were mostly detected by simple manual detection methods, and the detection of microbial indicators was more complicated; 2) According to statistics, some soils in North China were alkaline, which was the main factor affecting the physical and chemical properties of other soils in the region. In addition, the forest management measures and management methods of plantations will also have a greater impact on the soil.
